"Y-What do you mean?"

Director Zhufu's face turned pale: "Could it be that the murderer is among us?" ”

"That's right," Hattori looked at a few people, "Miss Hirara, the director, you and Mr. Daito both disembarked after us, and the last person to leave the ship at that time could take the opportunity to kill the captain......"

"I'm the last to get off the boat," interrupted Uncle Serious, "but after I get off the boat, they can sneak back to the boat, and, brother, have you forgotten something?" ”

Uncle Serious snorted, "Didn't you say it when you found Kume's body before?" The murderer left those strange words before you arrived, how could we possibly do that? ”

"That's right," the man in the vest Ikema nodded, "You said that those words were written at low tide, and they didn't stay long, otherwise they would definitely be washed away by the waves......"

"Also, those words are exactly the same as the bloody handwriting on the ship, the murderer should be the same person, in that case, none of us can be murderers......"

The serious uncle smiled: "The murderer may want to set a trap, so that we think that the murderer is in his own people, and after falling out, he will fall into confrontation, so that he can reap the benefits of the fisherman." ”

Hattori frowned, and did not refute with a calm face.

These people are right......

"Okay," He Ye looked at the solemn atmosphere and hurriedly said, "Now that the ship is back, I see if there is anything to say, let's go back to the main island......"

"I'm afraid I can't go back," Gao Cheng walked from the wheelhouse to the deck, "the fuel on the ship can't last on the island, and the radio has been destroyed, and everyone's luggage seems to have been thrown into the sea......

Everyone looked at Gao Cheng with surprise on their faces: "How can this be?" ”

"It seems that the murderer deliberately wanted to trap us on this island......"

Gao Cheng walked down the ship with both hands, stopped past the captain's corpse and said, "For the sake of safety, you'd better wait for rescue in that house as before." ”

"Joto, what about you?" Hattori looked at Gao Cheng carefully.

"I don't care, find a room to rest first, and wait until dawn to investigate again, it should be rewarding."

"That's all it can be."

Hattori was unwilling to look at the pitch black sea.

……

In the second half of the night, although the weather did not improve, it did not deteriorate, except for the rough sea, there was no storm.

While everyone in the villa was napping, a dark shadow slipped out of the house, avoiding Hattori and Conan, who were hovering near the docks, and walked through the forest to the back of the island.

The undulating sea lapped against the sand, and through the faint light of the water, you could still see the words "I am a messenger of hell" and many messy footprints.

The dark shadow cautiously looked around, sneered, and carefully began to erase the words on the sand.

"Mr. Daito," a flashlight shone on the black shadow, and Gao Cheng and Hattori walked out of the woods, "It's so late, isn't it dangerous to come out alone?" ”

"What?" The black shadow froze, blocking the light that pierced his eyes, and looked at Gao Cheng with an ugly face, "Detective Chenghu? I just wanted to come over and look into it......"

"Really? Erasing the words left by the murderer is also an investigation? ”

Gao Cheng calmly stepped closer, the light shining on the half-erased text.

"What are you talking about, Detective Joto?" Uncle Serious stood up and said with a dry smile, "I just saw that there seemed to be a dark shadow and came to take a look, do you think I am a murderer?" I used to be ......."

"It's impossible to stay on the ship all the time, right?" Gao Cheng interrupted, "But what if these words were written before we gathered at the docks?" ”

The serious uncle was stunned and said, "Before the gathering? If you write it at that time, it will soon be washed away by the high tide, right? ”

"The premise is that the sea can wash it."

Gao Cheng walked to the edge of the undulating waves, chuckled and said, "Actually, when we found out here, there was no low tide at all, but just when the tide was full......"

"Haha," Uncle Serious said with a smile, "Don't be kidding, everyone has seen it, the body is wet one meter above the head, which means that the waves hit where the tide is full, and no matter how much we think about it, what we see is at low tide......"

Hattori shook his head and interjected, "I'm ashamed to say that we were misled by you like this, just because the sand on the beach was wet, we made a wrong judgment, thinking that it was the result of low tide at that time, but ......"

Hattori glanced at Gao Cheng depressedly and continued: "Actually, you just write these words in a place where the waves can't hit when the tide is full, and then it is enough to put the corpse next to it, and it is not difficult for you to do this if you are familiar with this place." ”

"It's funny," the uncle's face turned cold, "even if I use a bucket, I can't make the sand of the whole beach wet like that, right?" ”

"It's not a bucket, you're just borrowing the waves from the boat to make the higher part of the beach wet, and you should have expected the captain to sail around the island before the agreed meeting time......"

Gao Cheng took the sealed box from Hattori's hand and opened it, revealing the golden screen inside.

"You know that the captain will look for this golden screen that was originally sunk at the bottom of the sea, but was washed away by a typhoon, and was called 'Princess' by the bandit group......"

"Princess?"

"Don't say you don't know, the sentence left on the wooden pillar will be incomprehensible if you look at it alone, but if you combine the story of Taro Urashima with this island, you will be able to know the code......"

Gao Cheng looked at the serious uncle quietly.

"Yes, it's Urashima Taro and Sea Dragon Palace that are casually mentioned in front of the house, and the A and B in that sentence are not A and B of A, B, C, and D, but refer to the tortoise shell and the princess Otohime in the Sea Dragon Palace, so the meaning of the whole sentence is that the place where the princess sleeps is not in the sea, but in the tortoiseshell-like forest of this Ghost Turtle Island......

"Back then, the bandit group sealed the golden screen in a box and sank it into the sea with an anchor along with a small boat, but it was hit ashore by a typhoon, and the most obvious evidence is the small boat that is now hidden in the forest, the broken anchor is still on the seabed near the pier, and only a piece of iron chain is left on the hull of the ship......"

Seeing that Uncle Serious frowned and didn't speak, Gao Cheng continued: "When the typhoon hit, one of the robber groups ran to this island to check the situation because he was not at ease, and found that the boat sunk in the sea was washed up on the island, but before he could inform his companions, the boat he was on was blown away by the typhoon, and he was trapped here before he wrote those words for his companions......

"Later, if you notice the meaning of the text, you will use the opportunity of the start of the filming of this mystery show to take revenge on the bandit group that may come, because if they still want to find the screen, the best chance is to disguise themselves as staff members and infiltrate this island......"

"Really?" Uncle Serious laughed, "It's quite an interesting reasoning, it seems to be true." ”
