"What clues?"

Sato involuntarily straightened up at this time, his eyes were blazing at Kurosawa Gin, and his eyes moved slightly. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The rhythm of the topic was obviously completely grasped by him.

Kurosawa Silver didn't deliberately sell it, and after taking a sip of the mineral water that was placed not far away, he still confessed his thoughts in the tone he had just said.

"The murder weapon was a wire with Toda's fingerprints on it. ”

"The most basic way of getting the murder weapon is to ask Mr. Higashida to go to his house to help repair the wiring, and then intercept the wire to commit the crime - I think this is also the most flawless and easiest way, I won't say more. ”

When Kurosawa Silver said this, he didn't forget to turn his head to look at Higashida, and pouted: "Mr. Higashida, you should be very good at repairing this kind of thing, right? Even if you don't, I think you often do this kind of work, because you can clearly see certain scratches on your fingers." ”

"That's right. Dongtian was stunned for a moment when he heard this, and then nodded his head in agreement, and in the process, he suddenly had a flash of inspiration and added, but his voice was inevitably a little low.

"I remember not long ago, I helped Beichuan get his equipment......"

"At the time, I was still very puzzled why he asked me to come over and pretend when all his things were intact, but now I think about it, hehe......"

"I don't understand why, we are obviously very good friends, why did he choose to do this......"

"Knowing people and knowing faces does not know hearts. Sato silently added a sentence next to him, and then shifted his gaze to Kurosawa Silver again, urging, "Kurosawa, didn't you just say that in your eyes, the murderer actually has two methods of committing crimes, what is the method of committing crimes?"

"The two methods I have mentioned are far more difficult to carry out than the methods I have just deduced, although the probability of not being discovered afterwards is close to zero. Kurosawa shrugged his shoulders, first selling a small pass, and then smiling and conveying his thoughts.

"Now that the murderer has been determined to be Kitagawa, I will start with Mr. Kitagawa's actions, so that you must know more deeply and thoroughly. ”

"One of the key points in this case is that the time period of the case actually happened before you, that is, Mr. Higashida and Mr. Kitagawa supported each other back to the apartment. ”

"It stands to reason that you can't commit a crime, and it is impossible for Beichuan who is traveling with you to commit a crime, but Beichuan's blame is a complete success. ”

"There may be an objective reason for this—that is, the police are focusing their search on you, Higashida, and it is also an indispensable, subjective reason—that he went to Miss Muranishi's apartment to strangle you when he went out of the tavern with you and went home. ”

"The reason why Kitagawa chose such a troublesome back-and-forth twist is also very simple, that is, if Miss Muranishi is still alive when you are brought to Miss Muranishi's room, then the success rate of the case will plummet to close to zero, so Mr. Kitagawa will act in advance. ”

"But there are advantages to doing it early. ”

Kurosawa Silver paused deliberately when he said this, and the corners of his lips rose slightly in a faint arc.

"For example, he can get the key from Miss Muranishi and enter and exit the room without any problems, so that the secret room trick will be self-defeating. ”

"Wait a minute, that's not right. Sato frowned slightly at this time, and abruptly interrupted Kurosawa Gin's words, "If the key is at stake, our police found it on the washstand next to Miss Muranishi in the bathroom, so your assumption is not valid." ”

"Detective Sato, there's one thing I want to emphasize solemnly. Kurosawa Silver turned his head sideways and smiled at Sato, "You must know that the first discoverer is always the first discoverer, and they have access to the case faster than the police, so it is only appropriate to do anything during this time period." ”

"You mean, after entering the bathroom, Mr. Kitagawa threw the key back again?" Sato raised his eyebrows, muttering to himself, but he couldn't help but clasp his chin and move his eyes slightly, "That's exactly what I said...... However, it is still not true. ”

"What's wrong?" Kurosawa asked rhetorically.

Sato simply conveyed the truth he knew.

"Mr. Kitagawa used the phrase 'I found out that my boss and colleagues didn't come to work in the morning' as an excuse to go to the scene of the crime, and he asked the administrator of the apartment to go with him to Miss Muranishi's room to check on the situation, and if necessary, open the door and break into the room. ”

The caretaker of the apartment didn't want to do this for no reason, he just wanted to use the key to unlock the door and push the door open a crack to say hello, but in the process, he saw Mr. Higashida, who was not supposed to be on the bed in the room, so he pushed the door in. ”

At that time, the anti-leeching chain was strong and well, which was obvious to both men. ”

Sato looked at Kurosawa Gin: "How do you explain?"

"Well, just by what you just said, I can turn my guess into conviction. Kurosawa Silver inevitably let out a loud laugh.

Sato was stunned: "What do you mean?"

"It's simple. Ordinary anti-leeching chains, under the premise of locking, push the door open to the maximum, no matter what, you can't see the bed in the bedroom, if you add a chain buckle, naturally it's a different matter. ”

"It's really possible for Kitagawa to knock the drunken Mr. Higashida unconscious, and then use the key to enter and exit the room, and then directly reach out and hang the chain outside the door, and leave the room as if nothing happened, and when he comes back the next day, he throws the key next to Miss Muranishi's body, and completes a secret room crime. ”

"I think that in the case of the discovery of the body, the administrator who was traveling with him had no time to care about what Beichuan would do, so if Beichuan wanted to do this, it would be easy. ”

When Kurosawa Silver said this, he couldn't help but pause slightly, tilted his head to look at Sato, and pushed his glasses on the bridge of his nose again, and a faint faint light suddenly crossed his eyes.

"However, if according to what you said, Beichuan did not use the key, then there are other ways to commit crimes. ”

"It's just that you need to be prepared in advance, and it's impossible to do it if you commit an impulsive crime. ”

"If you want to do it, it's also very simple. ”

"The simplest way, that is, Beichuan only needs to purify the medicine like sleeping and prepare it into a very concentrated solution, and give it to Miss Muranishi with a little disguise, and the other party can paralyze the respiratory muscles and suffocate in a short time after taking it. ”

"Of course, this method is easy to be verified by the police, and there are too many unstable factors, plus if you use this method, there is no need for wires and blame, so it can be ruled out. ”

"It's a little more complicated...... All it takes is a little more investigation, and Miss Muranishi just agrees with what she expected. ”

"For example, suffocation may also be a symptom caused by allergies, and in order to make this suffocation to the point of death, the murderer may only need to pack a certain ordinary food and send it to Miss Muranishi for use, then she will definitely die after taking it. ”

Similarly, as long as the work is done well in advance, the police will definitely not have any clues, and Miss Quan Dang Muranishi suffocated to death by eating the food she was allergic to, and the case was handled hastily. ”

And if the wire with Mr. Higashida's fingerprints is thrown next to it, and Mr. Higashida reappears at the scene of the crime at this time, then it can be explained by the sentence that Mr. Higashida used food and wires to kill people twice. ”

“...... Well, this time Mr. Higashida will go in, and Kitagawa doesn't need to let him misunderstand that this is his room, and he doesn't need to be stunned, he just needs to casually tell him that Miss Muranishi wants to discuss tomorrow's work with him alone and invite him to have a glass of wine by the way, then Mr. Higashida will also go in and fall into the trap. ”

"That's it, I know, three ways to crack the chamber. (To be continued.) )
