Ke Xue: Shinichi and I are childhood friends

Yuya shook his head: "Of course not. Mr. Sakano, what kind of fish do you think can pull a grown man into the water?"

Daigo Sakano thought for a while and said: "Mr. Urata has rich fishing experience. It is impossible for ordinary fish to pull him into the water. No, even a fish weighing dozens of kilograms can't pull him into the water, right?..."

Yuya agreed: "Yes, it was raining heavily at the time. The murderer knew that Mr. Urata was very good at fishing in bad weather. Therefore, when he saw Mr. Izu and Mr. Sakano return empty-handed, he would definitely volunteer to go fishing."

"But how did the murderer get Mr. Sakano into the water?" asked Daigo Sakano.

Yuya suddenly realized that Inspector Shiratori was not there, and this Sakano Daigo played the role of the supporting actor very well. He has a future~

Yuya said: "I'm afraid he used an underwater propeller. I found it in the warehouse of the hotel. It should be what Aunt Kirio usually uses to fish?"

Kirio nodded: "Yes, I'm old, and I need a propeller to go into the water to fish."

"That's it. The murderer grabbed Mr. Urata's fishing line and used the underwater propeller to pull Mr. Urata away."

Sakano Daigo laughed and said: "It's ridiculous. In that case, wouldn't it be enough to just let go of the fishing rod?"

Yuya shook his head: "Even if Mr. Urata wanted to let go, he couldn't. I'm afraid that there was super glue on his gloves or fishing rod. The murderer should have put the super glue in a container like a capsule that would break if squeezed hard.

When the fishing line was pulled, Mr. Urata would naturally think that the fish was hooked, and he would subconsciously hold the fishing rod tightly. In this way, The super glue will leak out of the capsule and stick the gloves and the fishing rod together.

Mr. Urata's gloves have anti-slip Velcro on the wrist, which will not come off easily, but there are no gloves on Mr. Urata's body.

If he really drowned accidentally, how could he have the opportunity to take off his gloves?

As for the gloves and fishing rod, I am afraid they have been disposed of by the murderer and cannot be found.

However, his recovery of the gloves and fishing rod also made me suspect that Mr. Urata's fall into the water was not an accident, and later, I found evidence that could incriminate the murderer in the video taken by Ms. Ishida. "

Sakano Daigo asked anxiously: "You talked for a long time, so who is the murderer?"

Yuya slowly raised his hand and pointed at someone slowly and firmly: "The murderer who set up a careful plan and committed three murders is you, Izu Takeshi!"

"Mr. Izu?"

Others looked at Izu Takeshi in shock, but Izu Takeshi was indifferent and looked at Yuya with a calm expression.

"Stop talking nonsense," Izu Takeshi sneered, "Why do you talk nonsense?"

Yuya didn't care at all, took out Ishida Nanami's camera and said, "Don't worry, this is just the beginning. You can watch this video first and then make a judgment."

Yuya played the video of him and Shiratori Renzaburo returning to the hotel for help, and then paused the video. The screen showed Izu Takeshi's profile.

"Take a close look at Mr. Izu's face."

Others came up and took a closer look, and made a puzzled sound: "There seems to be a red mark on the face?"

"Is this, the indentation left by the goggles?" Kiriu suddenly spoke, and everyone looked at her.

Kiriu was a little nervous, pinching her fingers and explaining, "Didn't I just say that I occasionally use the propeller to go into the water to fish, and I would wear goggles at that time, so I am still very familiar with this mark."

Everyone suddenly realized.

"That's right," Yuya agreed, "After Mr. Urata and we went out, you pretended to go back to the room, but you actually sneaked out and dived to drown Mr. Urata.

Then you went back to the hotel and pretended to have just taken a shower. When you came out, you should have confirmed that there was no mark from the goggles on your face, right?

Unfortunately, you didn't expect that the sea water temperature was relatively low. After returning to the room and taking a shower, the body temperature rose, and the blood circulation also recovered faster, and the mark from the goggles also appeared."

Izu Takeshi looked a little dazed. He suddenly came to his senses and said, "Wait, you said this as if you were sure that I was the murderer."

"When Miss Hanye and Mr. Wuying were killed, I was with you all the time!"

Yuya glanced at the time and said, "It's almost time, so let's first solve the method of Miss Hanye's murder."

Bringing everyone to the outside of the hotel, Yuya pointed to the window of the salon and said, "Everyone, please look over there."

A crossbow was fixed on the railing, and the arrow was pointing into the room.

Sakano Daigo was the first to run over, and Yuya quickly reminded him: "Be careful not to touch the wires above, it will be troublesome if you get hurt by mistake."Sakano Daigo was startled and quickly stepped back.

"String?" Ishida Nanami walked forward carefully and found a string, one end of which was tied to the trigger of the underwater crossbow, and the other end was fixed to the wall with a pin.

Yuya squatted down and came to the other side of the crossbow, pushed open the window of the salon, and inside was a chair facing the window, on which a temporary dummy was tied with pillows and quilts.

"Everyone, look carefully, there is more than one string on it." Yuya reminded.

Everyone then discovered that there was another string connected to the trigger of the crossbow, extending all the way down and tied to a small boat.

"This first string is a safety device to prevent the trigger of the underwater crossbow from firing prematurely due to the floating of the boat..." Yuya explained.

Nanami Ishida suddenly realized, "This second line is used to pull the trigger by using the boat, right?"

Yuya nodded in appreciation, "Yes."

He suddenly raised his head and listened for a while, and said, "It's time."

The siren cry from the sea surface changed.

"Everyone stay away." Yuya said.

Everyone hurriedly stepped back.

After a while, the boat began to slowly move away from the shore.

Yuya began to explain synchronously, "Using the ebb tide of the sea water, the boat will slowly move away and pull the fishing line at the same time..."

As the boat pulled, the first line as a safety device was pulled off, and then, as the boat got farther and farther away, the second line wrapped around the trigger became tighter and tighter, until it reached a critical point...

"Swoosh!"

With a sharp sound of breaking through the air, the crossbow arrow was fired from the crossbow, almost reproducing the scene that night, and shot straight into the dummy's head.

"... Just like that, the murderer doesn't need to stand outside to kill Miss Han Ye."

"Then, due to the recoil and the pull of the boat, the underwater crossbow will fall into the sea, and the murder weapon will be hidden. We just need to find time to recover it later."

Everyone stared in amazement at the crossbow arrows that automatically fired to "kill" and then automatically hid the murder weapon, their faces full of shock.

You also looked at Izu Takeshi and said slowly: "Mr. Izu, this is the automatic killing device you designed that uses the receding tide of the sea water!"
