"So the main problem now is the secret room technique?" Mizumatsu confirmed.

The tape has been taken for inspection. Now the main problem for the police officers is in the cracking room. Although the cracking room cannot cracking the room and will not delay the accusation of the murderer, the murderer was given an excuse during the prosecution process.

The crime scene was the deceased's study room. When the body was found, the door was locked, and the only key was pressed under a notepad at the scene.

The officers estimated that the key was taken in from under the door after the murderer locked the door, on the grounds that there was a brand new scratch on the floor, and it was a straight line from the door to the notepad. At present, it is speculated that the most likely thing is the trace of the key being scratched.

However, the problem is how to get the key under the notepad. The police officers found a similar key and used various methods to try it out, such as rubber bands and thin bamboo sticks. As a result, the keys were all 108,000 miles away from the notepad.

"Let me try it." Wei Xinghu, who had been watching the fun, suddenly spoke out, picked up the key and placed it on the ground, neither using rubber band nor thin bamboo sticks. Just flicked his fingers and the key flew in through the crack of the door.

A burst of exclamations rang out from the door. When I opened the door, I saw that the key really flew to the same place as before.

However, Mizumatsu picked up the notepad and found that the key was not under the notepad but inside the notepad, because the opening of the notepad was facing the door.

"Uh, can I try it once?" Wei Xinghu was dissatisfied.

"Even if you happen to bounce it down, it won't mean anything." Mizumatsu hit: "Look at the opening side, there are several pieces of paper damaged at the edge of the opening. This is caused by the key bounced into the notepad. Even if you bounce under the notepad, it will leave such damage on the back cover." The notepad covered on the key at the crime scene has no such trace.

"I have a way." Wei Xinghu walked out the door with the key again, and Shui Jianyue stayed.

After a few seconds, the key flew in through the crack of the door, hitting both walls in succession, and placed it in opposite directions from the opening of the notepad to the bottom of the notepad. Because the other section was sealed, the key bounced into the bottom of the notepad without any trace.

Wei Xinghu came in arrogantly, "Is there any problem this time? Just scratch the scratch in advance and you can reappear on the scene."

"It just has no reference value." Mizumatsu continued to break the cold water channel. "If the murderer has the ability to do it, no one will deliberately leave scratches."

"Tsk." Wei Xinghu curled his lips and continued to watch. Mizumatsu said that there was news from the Black Organization that he had just arrived, but he could only stand here stupidly. He was actually a violent law enforcement job in the Interpol, so he couldn't get involved in solving the case.

"But if I talk about it, I remembered a device." Kawasaki Hideki suddenly said, "When I was a child, I often used a basket and bamboo sticks as a trap. When I put down the bamboo stick basket, I would be locked off. Could it be such a mechanism?"

"It's possible." Kenichi Nakamura touched his chin and said, "Although there is no bamboo stick, the chess pieces next to the notebook seem to be able to use them."

"By the way, the situation is a bit like the American case that Fujiwara explained last time, right?" Kodenmi, forensics, suddenly said.

"Well, the clues are not clear yet, and you can't draw conclusions." Fujiwara Sakagi of the Forensics Department thought for a while, shook his head and said.

At this moment, the identification results of the tape have come out. The fingerprints of the deceased and the deceased’s wife were found on the surface of the tape, and an unfamiliar fingerprint was found on the tape. Now three people who appeared at the scene of the crime need to cooperate to collect fingerprints and compare them.

PS: The question about the tape running into the backyard instead of lying obediently in the answering machine like in the original work is because the body of the original work was discovered by Conan, and the reason why Shirakura Yang came back was to be the first person to secretly take away the tape with his fingerprint. Now Conan did not come. Assuming Shirakura Yang successfully stole the tape, the police came soon. In order to avoid being discovered, Shirakura Yang threw the tape into the grass in the backyard, he was finally found by the forensic department. Shirakura Yang did not take the opportunity to wipe off the fingerprint on the tape first because time was limited.
