Chapter 18 Section 17

For example, let us consider the situation when the murderer went to the Banqiao branch of Yasuda Bank to collect a check on the 27th (Tuesday).According to the general situation, the murderer always wants to cash the check as soon as possible before the notice comes down; therefore, it is safer to go in the morning than in the afternoon.But in fact the murderer did not show up until 3:30 in the afternoon.That is to say, he could only be free in the afternoon on Tuesday.Then it can also be imagined that since the murderer is going to commit such an important case, maybe he will ask for leave to do it?But if you ask for leave on the day of the crime, the suspicion is even greater.

Secondly, the murderer chose a remote small bank near which many houses were destroyed by air raids.There are only twenty or thirty employees in this kind of bank, that is to say, it is probably just right in terms of the number of people.His range of action is from Itabashi in the north to the vicinity of Shinagawa (Ebara) in the south; Shiinamachi and Nakai are in between.He also appeared in Ginza for custom business cards.It is true that his scope of action can be said to be all over the north and south of Tokyo.Of course, he went on a different day.But if he can leave his post only in the afternoon (and he always arrives at the scene after three o'clock), and he can't get out before then, a kind of mobility can also be seen from here.

Especially when he went to the Shiinamachi branch of the Imperial Bank to commit crimes, it had just snowed and the road was difficult to walk. Defenders of Hirasawa said that Hirasawa was not at the scene because it was impossible for the 57-year-old Hirasawa to arrive at the scene in such a short time wearing rubber boots.This kind of argument is also worthy of reference-that is to say, I think the murderer probably used a jeep to have this kind of mobility. The murderer made a careful plan and committed the crime in the bank.He must also worry about whether someone will come in from the outside while the crime is being committed.For example, even though work is over, there may be a customer who comes in through the wicket because of business, or someone who is away from work returns.At such a time, as long as someone broke in from the outside and saw the staff fall one by one, everything would be over.The man would have run out immediately to call the police, and the murderer would be in trouble.In view of the delicacy of the murderer's plan, it would be unreasonable that he should not have thought of what to do on such occasions.He must be prepared and not just rely on fluke.

For example, is it possible to assume this?The murderer was a senior employee of the occupying army. He came near the bank in a jeep, parked the jeep in an inconspicuous place, and then walked into the bank.As long as he puts a light overcoat on the outside, people don't know what he's wearing underneath.In fact, although the bank clerks could not remember the killer's attire, they said he was wearing a coat.In case anyone was chasing him, he immediately ran into the jeep and drove away.At that time, the jeeps of the occupying army used yellow license plates, and the Japanese police could not easily check them; and from the 22nd to the beginning of the 23rd year of Showa was the period when the occupying forces were at their most powerful.

However, according to the investigation outline, the authorities initially looked for clues to the car, but then gave up.Probably because only Japanese cars can be used as targets of investigation, and jeeps of the occupying army are of course not within the scope of investigation.
