This September is different from previous years, the temperature is very low.There are not many people in the swimming pools in Tokyo; but most of the young people who come back from swimming in other places have very tanned skin. In recent years, the range of activities for young people has expanded.Most of them left the Japanese mainland to play in Ryukyu, Guam and Hawaii, and sometimes even went as far as Tahiti to enjoy the bright sunshine there. Yumiko Hashida of RS Trading Company is one of the girls who travel abroad.She has worked for the company for three years after graduating from technical school with a monthly salary of 120,000 yen.There is also a bonus of five months in winter and summer each year.She lives with her parents, saves the rent, and enjoys all the income by herself. She can be called a single nobleman among Japanese youths.

Not long ago, Yumiko took five days off to travel alone to Cebu Island in the Philippines.Cebu Island is a hot tourist destination recently, where the waters full of coral reefs are very beautiful.During her travels, she played love adventure games with Filipino youths and Japanese youths who lived together in tourist hotels. The strong sun tanned Yumiko's skin to a dark brown. It was the end of August when she returned to Japan.She was young, tall and slender, in harmony with her dark brown skin. A gold necklace gleamed across her breast-baring brown breasts, making Yumiko even more sensual.

“Single nobles are awesome!” The middle-aged men in the same department are very envious of her.In addition to Yumiko, there are six other single female employees who have also traveled to Guam and Hawaii and got a deep tan. Yumiko's parents, especially her mother, want her to get married as soon as possible.But she still wants to enjoy the celibate life for another two or three years.If married, the husband must also be an office worker.Yumiko once said while chatting with her unmarried female colleagues: "If you want to get married, you'd better marry someone from a rich family, so that you can travel overseas at least once a year. Otherwise, what's the point of getting married?"

However, she knew in her heart that her object must be an ordinary office worker.Thinking of traveling overseas is purely a dream. So she decided to spend another two or three years living alone, and next year go to Tahiti to have a good time. Yumiko can drink a little wine, and she likes to joke with her close friends while drinking. After get off work on September 5, she and three friends from the junior college days went to Ginza for a small gathering, drinking and chatting.One of the three is about to get married, and this party is also for her congratulations.It was past 10 when the party ended.Yumiko's house is 12 or 13 minutes walk from Luhua Park Station.This is the favorite place of Tokutomo Roka, a famous Japanese poet in the past.After she broke up with her friends in Shinjuku, it was past 11 o'clock when Yumiko arrived at Luhua Park by car.

Recently, many buildings have increased rapidly in this area, but most of the shops in front of the station are closed and lights are turned off late at night.Her father told her: "If you go home at night, you must call, and I will pick you up at the station." But 24-year-old Yumiko always felt embarrassed to disturb her father.She didn't call today either, and walked home boldly. There are many old farmhouses in this area, with long continuous wooden walls and dim and sparse street lights.Yumiko raised her eyes and looked at the lights of her own house not far away, feeling much more at ease.

At this moment, a black figure suddenly jumped out of the dark alley. "Ah!" Yumiko yelled in shock.At the same time, her neck was tightly strangled from behind.Her body was dragged involuntarily to a dark and dark corner. Yumiko struggled desperately, but it was useless, only a man's voice whispered in his ear: "If you move again, I will kill you!" At 6:07 a.m. on the 6th, the criminal police of the Setagaya Police Station received a report of a homicide: a young woman's body was found in a miscellaneous forest near Luhua Park.Interpol Yasui and Tajima rushed to the scene immediately after hearing the news.

Yasui just celebrated his 42nd birthday three days ago.Tajima, who rushed to the scene with Yasui, was in his early 30s. He was slender and handsome, but his life was not going well. He divorced his wife of five years at the end of last year.Alimony of 5 million yen was paid by loan.The purpose of Tajima's divorce is also to enjoy a free celibate life again. The scene of the murder still retains a strong sense of Musashino in the past.However, due to the expansion of construction projects, the original green trees gradually decreased.The miscellaneous woods where the corpses are buried are one of the few places that are left with greenery.The maple leaves were not yet red, and the corpse was lying under the slightly yellowed leaves, completely naked.Yasui thought she was wearing a bikini, because the young girl was so tanned that the traces of the swimsuit were so distinct that it looked like she was wearing a white bikini.

Tajima squatted down and turned the corpse on its back.This female corpse is very sexy, with slender thighs, face up, covered with mud. Yasui looked at the female corpse, and muttered: "Are you twenty-four or five years old?" Tajima said regretfully: "It's a pity that such a young girl was killed." The medical examiner set out to examine the body.Yasui meets the man who found the body. It was an ancient and rare old man who found the female body.He likes to run in the morning. He started to go out at 5:30 this morning. He found the body when he went to the miscellaneous woods to relieve his urge to urinate.

After the old man narrated the simple process, he took off the towel hanging around his waist and wiped his sweat while saying: "It's so pitiful for being so young." "do you know her?" "I don't know her, but I seem to have met her somewhere, maybe I met her two or three times in the car..." "A person from this area?" The old man thought for a while and replied: "I think it's probably from around here." The criminal police took pictures at the scene, and the forensic doctor also completed the autopsy.Yasui asked the forensic doctor Ogura after the autopsy:

"How about it?" Ogura held the depth myopia mirror with his hand and said: "It was obviously strangled to death, and the bruises were very obvious. It must have been killed late last night. And... she was raped." "real?" "This is a typical rape-homicide case." "Really?" "What? Is there anything you don't believe?" Anjing said apologetically: "Ah... no, no, no. You worked hard." Ogura-kun has a favorite phrase of "typical".Because it is used in rape and homicide cases, this "typical" adjective greatly stimulated Yasui and made him very sad.

"Anjing-kun." Tajima called him in the miscellaneous forest. Yasui stepped on the fallen leaves, and there was a "rustling" sound under his feet. Twelve or thirteen meters away from the corpse, there was a shallow pit for a bonfire, in which were possibly the victim's clothes, shoes and handbags.Tajima, wearing gloves, was rummaging through the contents of the handbag.Seeing An Jing approaching him, he said: "Here is an ID card. Her name is Yumiko Hashida. She is 24 years old and works in the Accounting Department of RS Trading Company. She lives in Kasuya 2 Lane, Setagaya District, not far from here." "So she was killed by gangsters on her way home from get off work." "Maybe. There may be gangsters who attack young girls often in this area. This is a new community, with open spaces and miscellaneous trees. Hey, come here!" Tajima greeted a nearby police officer and handed him the ID card of the deceased: "You go to this place. If there are family members, ask them to come to the scene." Yasui looked at the clothes of the deceased and asked Tajima: "Where's the wallet?" Tajima checked the handbag again and said: "I didn't find the wallet, maybe after being raped by the murderer, I took it away!" "Is it because of stealing money that led to rape and murder?" "It doesn't matter which one, the result is the same." "No, not at all." Anjing said: "Whether the gangster's original purpose was to rape or rob, although the result is the same, the type of murderer is fundamentally different." Relatives of the victim arrived after hearing the news. After confirming his daughter, the victim's father told the police that his daughter didn't come home last night, so he didn't go to work today and was looking for her daughter's whereabouts everywhere.The victim's mother was short, and when she saw the corpse, she hugged the corpse with a "wow" and cried bitterly. Yasui looked at the victim's mother silently, and felt very sympathetic after hearing their cries.He didn't want to ask them immediately, so Tajima had to do the job of asking the parents of the deceased.Under such circumstances, Yasui felt that Tajima was more suitable as a criminal policeman than himself. The father of the deceased said that at 7 o'clock last night, Yumiko called home and said that she would go to Ginza to meet a friend from the technical school days.At 10 o'clock in the evening, I called back from Ginza and said that I would go home soon. "I said that if it's late, call home from Luhua Park Station, and I'll pick her up..." said the father angrily. The mother wept and stood up from the corpse with difficulty. The body was removed and sent for forensic autopsy. "Do you have only one child?" Yasui began to question the parents of the deceased. "No, there is another eldest daughter who is already married." Mother replied in a low voice. "The victim, Miss Yumiko, is so tanned, where did she go this summer?" "She took five days off and went to Cebu Island in the Philippines." Father replied: "Does this have anything to do with her murder?" There was a sense of reproach in his words, and he felt that it was inappropriate for the criminal police to ask such questions. "have no idea……" Anjing didn't answer clearly.But even though Yumiko's body was transported away, Yasui's eyes still showed obvious traces of black and white on her body, especially when she turned her body upside down, her white and tender lower abdomen was really sexy compared to the healthy black of her whole body .Why did the murderer strip her naked?Is there any purpose here? When checking out the items brought by the deceased, it was found that only the wallet with cash was stolen, and the watch, clothes, handbag and an 18K gold necklace just bought were not lost. "What a mystery!" Anjing lowered his head and thought. "Do you mean the watch?" Tajima asked. "Yes, and the necklace." "Well, the reason is very simple. Cash is not easy to trace. Watches and necklaces are easy to find, so the murderer didn't take them. He thought it was very thoughtful." "I don't think so!" "The murderer stripped her naked because he raped the victim. If his purpose was just to rob her, he didn't need to take off her clothes! His purpose was to rape, and he took off her watch and necklace so that she had nothing on her. Do you think Thinking, here is a mixed forest, there are houses around, the murderer should finish the rape as soon as possible, but he even took off Yumiko's bra, doesn't that explain the problem?" "According to what you said, the murderer might want to appreciate the nakedness of the young girl. Because the moonlit night yesterday was bright and Yumiko's body was curvaceous, the murderer stripped her naked?" "But why did you take off your watch and necklace?" "So, I think the murderer took it off because he wanted to rob. But he thought the watch and necklace were easy to find, so he threw them away. The murderer is really not simple!" Is it really as Tajima thinks?Watches are for women, and it's a fact that sometimes they're hard to sell.The necklace is different. Recently, men often wear gold necklaces. This is just an ordinary necklace with no special features. That being the case, why did the murderer throw away the gold necklace he got? An autopsy proved that the deceased was indeed suffocated due to neck compression. The autopsy report presumed that the deceased was injured at 11:00 p.m. to 12:00 p.m. on September 5.The autopsy report also confirmed that the victim's vagina contained semen from a male, which revealed that the man's blood type was B. According to investigations near the station, Yumiko did get off the tram at 11:06 last night.At the same time, people who lived near the scene with such previous convictions were also checked. In the Setagaya Police Precinct alone, there are fifteen or sixteen frequent troublemakers: repeat rapists, perverts who steal women's underwear.They will repeat offenses even if they are arrested multiple times.When the underwear thief was arrested, a section chief of a large company was caught.He has passed his forty years, and he still has a wife and children at home.But he couldn't help himself when he saw women's underwear hanging out to dry.In the end he was fired from the company and his wife divorced him. All those with previous convictions were taken to the Setagaya Police Station, where the search headquarters is located, for the purpose of interrogating their alibi.As a result of the interrogation, people with type B blood had an alibi; those whose blood type was not clear at the scene were not type B.Therefore, all those with previous convictions are innocent. Yasui and the others didn't conclude that it was done by someone with a criminal record, or it might have been done by another murderer. Yumiko has two close friends at the RS trading company where she works.These two people are not her lovers, just boyfriends.Despite this, the police still went to investigate their "alibi".The investigation of the 30-year-old blood type B chief was more thorough.However, when Yumiko was killed, the section chief was playing mahjong with his friends, which has been confirmed. The rest is the boyfriend Yumiko met in Cebu Island.According to Yumiko's girlfriend, she once said that she played a love adventure game with two men when she was in Cebu Island.One is a Filipino youth and the other is a Japanese youth.When searching Yumiko's room, she did find photos taken during her trip to Cebu Island.There are two young men in the photo.The Filipino youth can not investigate for the time being, the key is the Japanese youth.The young Japanese in the photo is tall and tall, with long hair, about 27 or 28 years old.Although slender, he appeared to be muscular and strong.In swimming trunks, he stood shoulder to shoulder with a smiling Yumiko in a bikini. Following this clue, the search headquarters contacted the hotel in Cebu Island to learn some details of the occupants of the hotel at that time, and a week had passed unconsciously. September 12.Neither Yasui nor Tajima, who searched the headquarters, realized that this was a special day. For Shinsuke Miki, who works at the Ministry of International Trade and Industry, September 12 is not a special day.This day is neither his birthday nor a gathering of friends. Although he is 25 years old, he has no specific girlfriend yet. When he got off work that day, he suddenly wanted to go to the movies, so he went to a theater in Ikebukuro to watch an American sci-fi movie.Therefore, when he got off at Higashi Nagasaki Station on the Seibu Ikebukuro Line where he lives, it was past 10:30 pm.On the way home, I passed the stadium of N University.This is a shortcut, he often takes it when returning home at night.Today, Miki walked into the sports field through a gap in the barbed wire fence. He stopped to light a cigarette as he approached the players' lounge and the sports equipment room under the moonlight. Suddenly, a black shadow rushed out of the house.Miki yelled in surprise, then was knocked down by the black shadow, and the smoke from his mouth flew out. "asshole!" Miki cursed and got up from the ground.He felt severe pain in his left arm, and when he touched it, blood dripped down his finger.He was stabbed by the man who knocked him down. Miki quickly ran into a nearby police station, asked for a hemostatic bandage, and reported the situation to the police.Upon hearing the news, the police immediately picked up the flashlight and came to the scene with Miki. The policeman turned on the flashlight, and while looking at the place where Miki fell, he asked: "Did you see the other person's face clearly?" "No, because I stopped to light a cigarette, there was wind, I covered my head with my hands and lowered my head to light the fire, so I was knocked down without looking at the other person's face." "Did the murderer cut your wound?" "yes." "How tall is the murderer?" "I don't see clearly, maybe it's similar to me." "What is your height?" "1.70 meters." "How old is that man?" "Judging from his strength, he couldn't be an old man. I weigh 130 kilograms, and he knocked me down all at once." "Ok." "In the middle of the night, what is he doing in that room?" The police walked through the room while shining a flashlight on it.Miki followed suit. The door lock of the house was broken and fell to the ground.The door was ajar, and the policeman and Miki walked in back and forth. Under the light of the flashlight, sports equipment was piled up in disorder in the room. "Nothing." The policeman said something and continued to walk in.Suddenly, he yelled "Ah!", and the light circle of the flashlight stopped on a naked woman in the shape of "big" lying on the ground.It was a young woman, completely nude, the white streaks of her bikini standing out against her tanned skin. Miki watched from behind the policeman holding his breath. The policeman bent down to feel her pulse, and put his ear to his chest to listen carefully. "died?" Miki asked with a trembling voice. The police didn't answer Miki's question, they were still examining the body, and finally stood up and said to Miki: "Please wait here." As he spoke, he handed the flashlight to Miki. "what happened?" "It's a homicide. I'll report it to the police immediately." The policeman said and walked out of the house.Miki had no choice but to shine the aperture of the flashlight on the corpse, feeling extremely frightened.After Miki's expression settled down, he carefully observed the female corpse, thinking: "What a beautiful figure!" This female corpse swimsuit has clear traces, plump breasts, white and delicate lower abdomen, thick and thick pubic hair, giving people a strong sense of intuition and sexiness.Her legs were spread apart, she must have been raped too. Just as Miki was thinking, the siren of the police car sounded. Detective Shiraishi of the Ikebukuro Police Station quickly thought of the murder that happened in Setagaya a week ago after observing the corpse.Because the victim's tanned skin and white marks on the swimsuit were too similar to that case, and even attracted his attention more than the marks of strangulation. "It's too hateful!" The detective Aoki who came with him said angrily. The pain of tightening the neck made the victim's face distorted: the tongue was sticking out, the teeth were bared; the eyeballs were round and protruding from the eye sockets.There were stripped clothes and shoulder bags scattered in one corner of the room.Shiraishi immediately checked the contents of the leather bag.Among the cosmetics, handkerchiefs, and pocket money purses, I found a commuter ticket holder, which contained a student commuter ticket from Tocho to Ikebukuro to Ochanomizu.The victim's name was Qingmei Tanimoto, 20 years old; she was a third-year student in the English Department of S University, and her address was the Fushouzhuang apartment nearby. In order to confirm the victim, Aoki immediately called the management personnel of the apartment.During this time in the administrator's future, the medical examiner performed an autopsy.The investigators were busy taking photos at the scene.The killer may have worn gloves, but no fingerprints were found at the scene.Only a hole where a dagger had been inserted was found in the floor.The victim's underpants showed signs of being cut by a knife, which may have been cut with a dagger because the murderer thought it was troublesome to take them off. The apartment manager rushed to the scene with a pale face.He identified the deceased as Kiyomi Tanimoto herself.He also introduced that Kiyomi Tanimoto came to Tokyo from Fukui and lived alone in an apartment. "Her family runs a big hotel in Fukui. The family sends 150,000 to 60,000 yen every month." The admin added at the end. After listening to the administrator's narration, Shiraishi thought that if she had such a sum of money every month, she could lead a fairly affluent student life, but there was only change in her purse, and the murderer must have stolen the purse. The autopsy report was delivered the next afternoon.The cause of death was determined to be strangulation, and the presumed time of death was from 10:00 p.m. to 11:00 p.m. on the 12th. The victim was indeed raped.The murderer's blood type can be identified from the semen remaining in the vagina.It is quite similar to the case that happened in Setagaya Ashika Park.Therefore, a search headquarters was established in the first search section of the Metropolitan Police Department. The headquarters is presided over by the Totsugawa Police Department of the First Investigation Division, and the veteran Kamei detective will of course participate.In addition, the Setagaya Police Station sent Yasui and Tajima two criminal police officers, and the Ikebukuro Police Station sent Shiraishi and Aoki to assist. On the first day of the formation of the search headquarters, Totsukawa called a five-person investigation meeting. "Let's confirm what these two cases have in common, shall we?" Totsukawa said facing the blackboard.This seems to allow the image of the murderer to emerge. "The first is the murderer's blood type." Anjing said. "The murderer's blood type is B." Totsukawa wrote these words on the blackboard. "Perhaps by chance, both incidents occurred on Friday." Shiraishi from the Ikebukuro Police Station said. "I've noticed that too." Totsukawa said: "Let's just call this killer 'Black Friday.' Maybe there's something to Friday. Anything else?" "Also..." Yasui said, "In both cases, the murderer stripped the victim's clothes. In another recent rape and murder case, the murderer only exposed the victim's lower body, which is completely different from these two cases. Tajima said It's a motive for the murderer to rob, I don't think that's the case." "You think that reveals the character of the murderer?" Totsukawa asked Yasui with interest. "Although it is not necessary to say so, it is also worth noting. In the first case, perhaps as Tajima said, the murderer wanted to rob and take off the watch after the murder, but because it was a female watch, he was afraid of being traced and threw it away. It seems that there was no murder Robbery. I think the killer's motive was to get the woman completely naked." An Jing shared his views. "Why would the murderer do this?" Totsukawa asked. "have no idea." Anjing replied honestly. "Do not you know?" "Sorry." "Besides, is there anything suspicious about the murderer?" "From the victim's point of view, both were very tanned with very visible swimwear marks." Shiraishi added a little more. "It seems so." "Both women are young, and both have suntanned skin on the beach. This may be a natural thing, and it may not have anything to do with the murderer's proclivities." "Did the second victim, Kiyomi Tanimoto, also go to sea in summer?" "I went. She and her friends went to Public Opinion Island for a two-week vacation. It is an island near Okinawa. There are tropical fish swimming around. Young people are willing to go." The young detective Aoki looked at his notebook and reported. "Have you been there too?" "Haven't been there, but I read about it in a travel magazine and hope to go someday." Aoki said with a smile. "Two weeks is enough!" Kamei sighed enviously. The six detectives here said it would take two weeks, but they didn't even have three days.Their faces were also very tanned, but it was all caused by walking in the sun for investigating materials. "Is the friend who went to Public Opinion Island together female?" Totsukawa asked Aoki. "Three men and three women, all college students." "Is there any boyfriend of the victim?" "She seems to be very close to Adachi Junichi, a student of S University. After investigation, his blood type is AB, and there is also an alibi." "What about the other two students?" "For the sake of caution, I have also investigated. The blood types of these two people are A and B respectively. The student with blood type B drove his girlfriend for a ride on September 10, had a car accident, and is still in the hospital , the alibi is very obvious. The student with blood type A is from another university. He said he was watching TV at home from 10:00 to 11:00 on September 12. The alibi is obviously unclear, but the blood type is different, and the student is very annoying Girls like it, there's no way he's going to rape." "Maybe." Totsukawa said. Was the murderer a loner without a girlfriend, or did he have a special hatred for young girls? Totsukawa spread out the map of Tokyo on the table and drew circles at the two places where the incident occurred. Kamei and the others stared at the map. "The murderer is still at large. Judging from the current situation, the lovers or boyfriends of the two victims have alibi certificates, and their blood types are different. The suspicion can be removed. Who do you think the murderer is?" "I think it is possible that the men who were related to the two victims disguised themselves as passers-by, raped them and killed them to silence them." Tajima raised her voice and said. "The two murder scenes are so far apart, this cannot fail to attract our attention." Anjing said: "If the first murderer can be suspected to be a person with a criminal record near the scene, but after investigation, they all denied it. But why did the second murderer choose to kill in East Nagasaki?" Totsukawa was listening carefully and thinking. "There is another doubtful point, that is, the relationship between the two victims and the murderer, which is worthy of serious consideration. Maybe the service staff of the store the victim frequented is the murderer; maybe the supermarket, beauty parlor, and tea shop are the ones we have arrested. The focus of the murderer; the ticket collector at the station is also suspicious. We can imagine that if a man has seen the victim many times and has an adulterous heart towards her, but the victim ignores her, the man will be punished. What do you think if you get a cold reception and hold a grudge, and even go to the point of rape and murder?" Kamei expressed his views. So everyone talked about it in a hurry. "If the shop's closed day is Friday, Kamei-kun is right." "That's not necessarily true. The two locations are too far apart. This is a fact. It's hard to think that the two stores in Luhua Park and Higashi Nagasaki have one person working as a clerk at the same time, because it's impossible!" The results of the discussion were mixed.The case remains a mystery. Why did the case happen on a Friday?Is there any relationship between the victim and the murderer?Did the murderer meet the murderer by accident, or did he kill the young girl as soon as he saw it?If the purpose is to rape, why do you have to kill the other party after rape? Based on the above questions, Totsukawa had to arrange for the criminal police to continue to conduct reconnaissance near the scene. Since the two cases occurred, newspapers, television and weekly magazines have had news coverage.Totsukawa and the others named the murderer "Black Friday", and the newspaper called it "Friday's Devil", and exaggeratedly wrote that they made the victim completely naked twice, otherwise it would not cause sexual excitement, so the murderer used sex A pervert who is addicted to killing.Newspapers and TVs also sensationally added headlines: "Will the murderer choose a new victim next Friday, September 19?"... Faced with these various news reports, Totsukawa was really heartbroken.He was afraid that some evil fool would actually imitate the murderer.Fortunately, after Sunday, no similar incidents occurred. At 2 o'clock in the afternoon on Wednesday, September 17, a letter was suddenly received at the search headquarters.There is only one piece of letter paper in the envelope.The paper reads: Black Friday September 19th! There was only such a short sentence written on the letter paper.Is this a prank by a cynical guy, or is the killer continuing to challenge the police?Totsukawa looked at the text message and thought deeply. This letter is written in ugly handwriting, but the pen is very strong. It must have been written by the writer with a firm grip on the pen. The writer did not leave his address and name, and the postmark was "Central Post Office".Why is it sent from the Central Post Office?Is it because he is afraid of being traced, or is the sender working near Tokyo Station? While thinking about it, Totsukawa handed the letter to detective Kamei and said: "All four of them went to investigate, and I would like to hear your opinion." Kamei took the letter, looked at the calendar hanging on the wall and said clearly: "September 19 is the Friday of this week." Totsukawa nodded: "yes." Kamei went on to say: "If this letter is the killer challenging us, a third young girl will be raped and killed this Friday." Totsukawa asked: "Don't you think it was a prank by the sender?" Kamei shook his head: "If it was a hoax, he would have caused more shock if he dropped the letter in a newspaper than if he had sent it to the police, and that would be the real drama." Totsukawa said: "Maybe it was given to the newspaper." As he spoke, he picked up the receiver and called the Central News Agency to find Harada from the social department.After the call was connected, Totsukawa nonchalantly asked if there were any such letters to be sent to the newspaper.Harada replied affirmatively on the phone: "There are no such letters and phone calls." "Really not?" After listening to Harada's answer, Totsukawa asked another question. "I won't make such a joke, have you heard any news?" Harada asked again seriously. "No, nothing, please, thank you." Totsukawa hung up the phone helplessly. From an objective point of view, since the sender only sent the letter to the police, it may be as Kamei said, it can be considered that the murderer is challenging the police.And the murderer didn't write superfluous words, only wrote "September 19 Black Friday".This direct, more worrying.Totsukawa felt that Kamei's opinion made sense, and asked again: "If I agree that this is the murderer challenging us, Kamei-kun, what type of person do you think this murderer is?" Kamei thought for a while and said: "To be honest, the blood type of this murderer is the same as mine." Totsukawa said in astonishment: "Oh, I didn't know you were also type B blood!" Kamei said: "I've heard that people with the same blood type have similar personalities. If this is the case, then the murderer's personality is very similar to mine." Totsukawa immediately answered: "That is to say, the murderer is usually serious and serious, very stubborn and very courageous." Kamei added: "On the other hand, it's rough, unreasonable, stubborn, and crazy." Totsukawa said: "Anyway, you won't kill someone." Kamei replied: "I can't be too confident. I remember when I first became a criminal police officer, I thought I was the guardian of justice and had a sense of mission. Of course, I also have this sense of mission now. But as the cases accumulate, time has passed. Some prisoners also have sympathy. Reflecting on myself, I feel that my position is wrong, and my self-confidence has also been shaken. Let’s take the murder case in Shinjuku last summer. It was a case in which a middle-aged man hacked a bank manager to death with a kitchen knife. .” Totsukawa said: "Yes, I remember this case. The murderer kept borrowing money, and his sister was raped by the bank manager; the wife committed suicide, and the sister became mentally ill." Kamei nodded and said: "At that time, I thought that if I were that person, I would also kill that nasty bank boss! From this point of view, I might also do murder. But I didn't become a murderer after all. I think I am a murderer after all. I'm a cop, I'm the one who arrests people, it's my luck!" Totsukawa said: "You said it very well! I also have the same idea. But this case is completely different from that one, and the murderer this time is not worthy of sympathy at all. He even killed two girls in a row to vent his desire You know, both of them will get married and have children, and they will truly build their own happy and happy families!" While Totsukawa was talking with Kamei, Yasui and Tajima, who visited the area near the first scene, came back.What news did they bring back? Search the office of a Kobundo chief. Section Chief Honda sat in the swivel chair in front of the desk, slightly shaking his fat body and asked Totsukawa: "How? Have you found any clues to the murderer?" Totsukawa replied seriously: "Unfortunately, we haven't found any clues yet. Yasui and Tajima just came back from investigating around the first scene of Setagaya, but they also found nothing." Honda asked: "Is there no one who saw the murderer with his own eyes?" Totsukawa replied: "At present, the only person who saw the murderer with his own eyes is an office worker in East Nagasaki. But this witness only provided the murderer's height of 170 centimeters. This alone is impossible to narrow the scope of suspicion." Honda asked: "And what about that letter?" Totsukawa replied: "We conclude that it was sent by the murderer." Honda asked again: "Is it the murderer's challenge book?" Totsukawa replied: "You can think so." Honda asked: "Should this letter be published in the newspaper? What is your opinion on this question?" Totsukawa said: "If it is published in the newspaper, it may get the cooperation and assistance of the public." Bendo nodded: "But if there is a third victim, the police will definitely be scolded, because the police failed in the murderer's challenge. The murderer has made an announcement. The police can't prevent it, and the news will accuse the police of incompetence. The minister is worried This is why we are told not to publish the letter for the time being. What do you think?" Totsukawa said: "So do I. At least for now I am not fully sure that the third case can be prevented." Honda asked: "Really not?" Totsukawa replied solemnly: "Not really. I think the next time it will be a young girl. But we only know that and the time of the crime. We don't know who the victim was or where, so there is really no way to prevent it." Honda asked again: "Didn't find out the relationship between the two victims and the murderer?" Totsukawa replied: "not yet." Honda asked: "Is there any possibility of running around and killing people?" Totsukawa said: "I think it's very likely." Honda said: "If the murderer's target was only young girls, it is entirely possible that he killed the third victim outside of Tokyo." Totsukawa thought about it and said: "What you said has some truth. But since the murderer has sent a letter to protest, I think he will still carry out his criminal plan in Tokyo. Tokyo, how big Tokyo is, I am also a little desperate." Totsukawa is right.The population of Tokyo is more than 10 million, and there are no fewer than hundreds of thousands of young girls.It is not easy to protect these hundreds of thousands of girls, it is almost impossible! "Then what do you think we should do?" Honda asked. "Please newspapers and television to appeal to all the citizens of Tokyo to ask all the young girls to go home before dark on the 19th. Maybe it will be helpful." Totsukawa said with a half-joking smile. "That can't be done. We will definitely be criticized. People will say that only two girls were killed and make such a fuss. What if there is a third victim?" Honda obviously disagreed with Totsukawa's approach. "Citizens are not friendly to the police. Because we not only wear a uniform, but also have pistols and batons. They are also happy when we get results in our work; if something goes wrong, they will attack it in groups. It is really helpless." Totsukawa said dejectedly. "What else do you think about the case?" Honda asked another question. "People are only afraid of a third victim, but they don't know how difficult it is to prevent it. Our criminal police have swollen feet and are accused of being incompetent in investigating the case. It's really pitiful." Totsukawa's words were full of complaints. "Is today the 17th?" Honda asked. "Yes. There are three days left including today. We will do our best to catch clues about the perpetrator so as to prevent the case from reappearing for the third time, but we should not be too optimistic." Totsukawa expressed his attitude. "Well, please. I don't want any more young girls to die." Honda said. "I will do it seriously." After Totsukawa finished speaking, he wanted to get up and leave. 本多见十津川起身欲走，又叫住他。 “田岛刑警也参加了这次侦破案件？” 本多问道。 “田岛参加了，他怎么了？” 十津川有些惊疑。 “在芦花公园被杀的由美子的父母来抱怨了。查访时，田岛刑警说死者'身材真漂亮'的话传到她父母的耳中了。” “知道了，我会提醒他的。” 十津川告辞走了。 十津川知道，32岁的田岛因妻子有外遇和他离婚了。十津川并不想用这件事来说他。品德方面，警察的确比其他行业的人要高得多。要是一般的上班族，喝醉酒纠缠一下年轻姑娘大概不会算什么事；警察就不同了，会受到报纸的痛骂，处理得不好，还要砸了饭碗呢！ 十津川基于这种认识，觉得只要工作能力强，对女人有点随便也无妨，因为警察毕竟也是有七情六欲的人。但既然科长点了田岛的名，还是应该提醒他注意的。 回到房间后，到东长崎一带查访的白石和青木也回来了。两人都没有掌握到凶手任何线索。十津川听了他们的报告后说了一句： “请把田岛叫来。” 身材高大的田岛来到十津川面前。 "Is there anything you can do with me?" 田岛俯视般地望着十津川问。 “由美子的父母对你有意见了。你说了受害人'身材真漂亮'的话，传到她父母耳朵了。” 十津川开门见山地说道。 "real?" 田岛满不在乎的样子。 “你不相信受害者的父母前来抱怨了？” “由美子是赤裸着被杀的，我又不能闭着眼睛，怎能看不到她的裸体呢？因为她身体确实很美，我才说了那句话，我并没有侮辱的意思。” “可是人家却生气了。下次去拜访时，你要向他们道歉。” “需要道歉吗？” 田岛不服气地瞪着眼睛说道。 “这类案件，我们很需要市民合作。如果被害人的父母疏远我们，对破案是不利的。这不仅是你个人的事情，所有办案人员都将遇到麻烦呀！你想，你一个人能解决整个案子吗？” “要是可以的话，我一个人去解决看看。” 田岛顶撞十津川的时候，他的老搭档安井过来解围说道： “你一个人干？可别忘记我呀！” 田岛沉默不语了。安井拍着他的肩膀说道： “我正好想起了一件事，咱俩去查访吧。” 说着硬把田岛拽走了。过了一会儿安井独自返回来，他向十津川诚恳地说道： “请原谅田岛吧。他虽然有点倔强傲慢，却是很能干的刑警啊。” “我知道他很能干。” “那么，一定要他去向受害人家属道歉吗？” “是的。他必须去道歉！” 十津川以不容商量的口吻说道。 田岛是否真的去道歉了，十津川再没有过问。他对田岛和安井这两位刑警是信得过的。 近日以来，最使十津川头疼的是那可怕的星期五正分分秒秒地逼来。尽管十津川他们已竭尽全力，那个飘忽不定的魔鬼无论怎样查访也找不到新的线索。唯一的目击者——通产省事务官三木也没有提供出很具体、很有价值的证据来。白石和青木已经几次拜访他，让他尽量提供些什么，但终未能奏效。 十津川下令停止了对三木的查访工作。因为如果一再反复讯问，三木有可能会编造出一些证据来，这样反而会使案件人为地复杂起来，甚至导致意想不到的坏结果。 市民们也向警方反映了不少情况。有人在电话中模棱两可地说，自家住宅附近常有一个男人徘徊，用异样的目光打量年轻女人，他们怀疑是强奸杀人的凶手，要求警方去查办。有的人更肯定地说，住在某处公寓的男子就是凶手…… 十津川一一派人去调查了报告人提供的地址，结果都与此案无关，其中还有女人跟男友吵翻，气愤不平打电话指控男友是杀人凶手，真是令人啼笑皆非。 在一无所获中，随着时间的流逝，凶手预告的可怕的星期五——19日来临了。 这一天从清晨就开始下雨。十津川因睡眠不足，红着眼睛注视着窗外濛濛的雨丝，心里暗想，如果那凶手是讨厌雨的人就好了。如果讨厌雨，他可能一整天都闷在家中，这样第三个受害者在今天就幸免了。可天不随人愿，也好像有意嘲笑十津川一样，中午刚过天就晴了。前两件案件都发生在夜里10时到12时之间。十津川仍认为这是个最危险的时间段。因此，东京的各派出所在今晚都增加了巡逻队的次数，还专门派人的在黑暗的巷道里蹲守。 时钟无情地走动着，时间一小时一小时地向前推进着。搜查总部里也越来越不平静了。安井和田岛径奔芦花公园；白石和青木则去了东长崎。 没有任何迹象表明凶手住在第一现场和第二现场一带，也没有任何证明判定凶手仍在上述两个地点作案。但对第一第二现场还是不能忽视的。 留在搜查总部值班的只有十津川和龟井两个人。他俩心似油煎，因为不安的等待比外出走动更令人心焦。 “9时30分了。” 十津川看看手表轻声说道，又点燃了一支烟。他办公桌上的烟缸里已堆积如山了。龟井默默地为十津川倒掉了烟灰。 “谢谢你了，龟井君。” 龟井轻轻摇了摇头，顺手推开窗户，深深吸了一口空气，望着长空说道： “好美的月夜呀！” 十津川心境不佳，凝望着苍白的月光，仿佛看着不祥之物一样。前两个案件发生的晚上，也是这样的月夜呀！尤其是第一件案件，凶手把由美子扒光，可能就是在月光下欣赏她那晒黑皮肤上明显的泳装痕迹的。 今晚凶手是否正在暗夜中到处走动，寻找新的牺牲者呢？ 过了10时，又过了11时，仍没有任何报告传来。 虽然没有报告传来，十津川沉重的心情并没减轻。案件也许已在东京都的什么地方发生了，只是还没有发现尸体而已。 电话铃突然响起来，十津川拿起听筒脸色顿时骤变。 第三起案件终于发生了。
