Chapter 31 Section 31

Kaoru stopped in front of the door.Although there is still a sign with the words "Apricot Yellow House" beside the door, but according to Kusanagi, the quilting classroom is basically closed now. Seeing this Kusanagi nodded, Kaoru rang the doorbell intercom.After waiting for a while, seeing that no one answered the door, Kaoru stretched out his finger towards the button again, ready to ring the doorbell again.Just then, she heard Yesung "coming".It was Ayane's voice. "I'm Utsumi from the Metropolitan Police Department." Kaoru put her mouth close to the microphone and said, trying her best not to let the neighbors hear.

After a moment of silence, another voice of inquiry came from the room: "Ah, it's Ms. Utsumi? What can I do?" "I want to ask you something, is it convenient for you?" Again there was silence.The scene of Ayane lost in thought on the other end of the doorbell intercom emerged in Kaoru's mind. "Understood, I'll open the door now." Kaoru turned to look at Kusanagi, Kusanagi nodded slightly at her. With the sound of unlocking, the door opened.Ayane showed a little surprise when she saw Kusanagi.Maybe she thought Kaoru was the only one outside the door.

Kusanagi looked down at Ayane and apologized, "I'm very sorry to bother you suddenly." "Mr. Kusanagi is here too?" Ayane smiled on her face, "Please come in, both of you." "No. Actually," Kusanagi said, "we want you to come with us to the Meguro Station." The smile disappeared from Ayane's face: "To the police station?" "Yes. We would like to ask you to go back to the office and have a talk with us slowly. In fact, it is also because the content of the conversation is a little sensitive." Ayane stared intently at Kusanagi, and Kaoru was also affected by her, turning her head to look at the profile of senior.Kusanagi's eyes were full of sadness, regret, and even pity, and Ayane must have felt how determined he was to come here at this moment.

"Really?" Ayane's gaze returned to tenderness, "In that case, I'll go along with the two of you. But I still have to spend a little time to prepare, so I can invite the two of you to come in and wait for a while Is it? Let others wait outside, I will feel bad in my heart. " "Okay, let's interrupt then." Kusanagi said. Ayane said "Come in", and opened the door. The room was neatly tidied up, and she presumably had disposed of some furniture and sundries, but the large table that was originally placed in the center of the room and used as a workbench was still in its original position.

"You still haven't hung that tapestry?" Kusanagi said while looking at the wall. "I don't always find time to hang up." Ayane replied. "Really? The pattern is very beautiful, and I think it is suitable for hanging. The design can be printed on a picture book." Ayane kept a smile on her face, looked at him and said, "Thank you for your compliment." Kusanagi shifted his gaze to the balcony: "Did you bring those flowers here too?" Hearing this, Xun also looked this way, and saw pots of colorful flowers outside the glass door. "Well, part of it was moved here." Ayane said, "I asked the people from the moving company to help move it here."

"Really? It looks like it was watered just now." Kusanagi looked at his feet and found that the huge watering can was still standing by the glass door. "Yes, this watering can is very convenient to use, thank you very much." "It's nothing, as long as I can help you." Kusanagi turned to look at Ayane and said, "You don't have to worry about us, go get ready." Ayane nodded, said "yes", turned and walked towards the next room.But the moment she reached out to open the door, she turned her head and asked, "Did you find anything?"

"What do you mean?" Kusanagi asked. "Some... new facts or evidence about the case. Didn't you two come here to send me to the police because you found something?" Kusanagi glanced at Kaoru, looked at Ayane again and said, "Well, not much." "This is quite interesting. Could you please tell me what you found? Or do you have to wait until I get to the police station to tell me about this?" Ayane's tone sounded bright, almost like It's like urging him to say something happy. Kusanagi lowered his eyes and fell silent for a moment, before speaking again: "We have already found out where the murderer poisoned. Various scientific analyzes have proved that it should be inside the water purifier, which is definitely true. "

Kaoru stared at Ayane's face, her expression was calm, she was still looking at Kusanagi with her water-clear eyes. "That's it, it's in that water purifier." There was no trace of embarrassment in her voice. "The problem is how to poison the water purifier. Judging from the situation at the time, there was only one method. In this way, the scope of suspects was narrowed down to one person." Kusanagi looked at Ayane and said, "That's why we asked you to come with us." Ayane's face flushed slightly, but the smile on her lips did not disappear.

"Have you found any evidence that the murderer poisoned the water purifier?" "After detailed analysis, we detected arsenic. However, this alone cannot be used as evidence. After all, the murderer had already prepared the poison a year ago. What we need to prove now is that the Whether the poison is still effective on the day of the incident. That is to say, whether the water purifier has not been used even once during this year, and the arsenic dropped has not been washed away by the water." Ayane's long eyelashes trembled slightly, and Kaoru was sure that she had reacted when she heard the word "one year ago".

"Then what can you prove?" "You don't seem to be surprised at all." Kusanagi said, "When I first heard the inference that the murderer had committed poison a year ago, I even wondered if I had heard it wrong." "It's because you have been saying some unexpected things, so that I didn't even have time to express my feelings." "Really?" Kusanagi winked at Kaoru, and Kaoru took out a plastic bag from the bag he brought. Until this moment, the smile disappeared from the corner of Ayane's mouth, she seemed to have understood what was in the plastic bag.

"You should know what's inside, right?" Kusanagi said, "This is the empty jar you used to water the flowers, and there is a hole in the bottom with an awl." "Didn't you throw away that thing..." "Actually, I brought it back, and it hasn't been washed yet." Kusanagi smiled slightly, and then his expression immediately returned to seriousness, "Do you still remember Yu Chuan? It's my friend who is a physicist. .I took the empty jar to his university for analysis, and arsenic was detected from it. Afterwards, we further analyzed other components and found out that the water flowed through the water purifier in the house. I have I still clearly remember the last time you used this empty pot. At that time, you were using it to water the flowers on the balcony on the second floor, and then Ms. Hiromi Wakayama came, and you didn’t continue to water it. After that, the empty can was never used again, because I bought the watering can later on. And the empty can was never used, and I put it in a drawer in my desk." Ayane's eyes widened: "Why did you put it in the drawer?" But Kusanagi did not answer her question, but said in a tone of suppressing the emotions in his heart: "From the above situation, we can infer that there was indeed arsenic hidden in the water purifier. The water coming out of the cistern contained a lethal dose of arsenic. Besides, there are indications that the arsenic was hidden a year ago. This can be done, and clean water can be kept from anyone for another year There is only one person with a weapon, " Kaoru nodded, observing Ayane's appearance.At this moment, the beautiful suspect lowered her eyelids and pursed her lips. Although there was still a trace of a smile on her face, the noble and elegant temperament surrounding her gradually faded away like the setting sun. A layer of haze shrouded it. "We'll discuss the details after we get to the office." Kusanagi decided to end the conversation at this point. Ayane raised her head and sighed heavily, looked straight at Kusanagi and nodded. "I see, but can you please wait for me a little longer?" "Yes, you can clean up slowly." "Not just tidying up, I also want to water the flowers again, because it's just halfway through." "Ah...then you're welcome." Ayane said "Sorry" and pushed open the glass door of the balcony.She lifted the human watering can with both hands, and slowly poured water.
