The cook is wanted by the police for committing a crime in China. Desperate, he had to board the passenger ship and wanted to go to a foreign country to escape the government's pursuit. However, in the communication with others, the chef found that there is an international law between the foreign country he is going to and the country he fled, that is, he will be detained by the customs when he arrives.
As the saying goes, people get wisdom quickly. As a chef, he often makes all kinds of platters. He thought of a terrible and very possible way to save himself: kill all the people on board, take their limbs and make fake bodies, and then burn the passenger ship, leaving his own things on the patchwork fake bodies to mislead the salvage team, thus forming the illusion that [the passenger ship has an accident and the passenger ship committed suicide].
The chef's first goal is blind people with limited mobility. He knocked on the blind man's door, took him to the deck, killed him in cold blood and cut off his head. However, when he returned to the cabin with the blind man's head, he unexpectedly met a college student.
College students didn't know that the chef was holding a blind man's head [it must be wrapped in cloth]. As an otaku, he just instinctively felt that the chef at that time smelled dangerous, so he wrote a 4 1 page diary.
College students and unemployed people were killed one after another as planned, and the whole passenger ship was in a panic. Everyone is wondering who will die next and who will be the murderer. The chef's mind is quite meticulous: the passenger ship has been sailing for four days, and if it continues to sail, it is too far from the coastline, which is very unfavorable for him to burn the ship and escape. After killing the old captain, he thought that the fisherman would probably sail a passenger ship, so he killed the fisherman, too. This is why there are two victims at a time: the murderer's plan is not careful, but forced by the situation. At this time, let's pause and analyze the diary again.
The key point of the diary is that the person who wrote it didn't know that the murderer would be a crab, and thought it was just an unfortunate incident that happened to him [maybe college students witnessed the crime scene]. Who knows that the murderer then killed him, so the owner of the diary is most likely a college student. Moreover, he wrote in his diary that [the man he met today] should be a college student who likes to stay in the cabin, and because he almost stays in the cabin, he rarely meets other people. So what else can be analyzed in the diary? The detective's eyes popped out when he saw a page in his diary. This is very clever. He knew the murderer even before he saw the contents of the diary, 4 1 page! The author puts this unimportant factor here, which should imply the age of the first 8 people, 4 1 year, chef! The detective turned and ran away. He guessed that the murderer would not let anyone on board go, so he ran out of the cabin before the chef could react. As for the missing body on the deck, it was a trap set by the author. The detective committed suicide by jumping into the sea. Whoever found a missing body was undoubtedly the engineer and chef who followed him. The missing body should be a college student, and the body was thrown by a detective. Then leave the blood number of [19] to remind the engineer, because in the cabin, if he reminds, then he can't escape, so he has to give the engineer one last hint before jumping into the sea in this way. Finally, my explanation of [19] and the reason why the body disappeared is a college student.
College students are 22 years old, and chefs are 4 1. 22+ 19=4 1. If the author reveals that the missing body is a college student, readers can easily associate it with two [4 1]: the age of the chef is 4 1, the page number of the diary is 4 1, and the age difference is 19. Moreover, engineers can be excluded. Generally speaking, the professional strength of chefs is greater than that of engineers. It takes a lot of effort to cut off people's limbs, especially their heads.
