Question 1: Yes

Second question: two

Third question: two

Fourth question: Four (excluding ghosts)

001: The lack of strength in the left hand means that it is impossible to cause a wound, being restrained means that the murderer has enough time to erase the traces of murder, and it is impossible for the murderer to create blood stains by himself, but there are blood stains and have dried up, and there are blood stains where blood stains are impossible, so the only person who can create blood stains is the murderer.

The first murder requires a motive, and the only motive is the ghost, but it is impossible for him to expose himself, so there are three possible behaviors.

1: Deliberately expose flaws to exclude one's suspicions, and let one's injuries be suspicious, but you can rule them out by thinking deeply.

2/ Really injured, have to be misled

3/ Intentional framing

The wounds of greed and concealment are on the left, and only Jane's is on the right.

Not knowing each other before coming to the hotel means that the ghost doesn't know that he is a forensic doctor, and the later article mentions that the bully is a detective, but the bully does not refute the results of the autopsy, which shows that the specialist is really a forensic doctor, not a lie.

As for the ghost who is specialized, she can't divide herself, you must know that the corpse after being divided has been carefully examined, so she excludes it.

Return, that is to say, the ghost is not aware that the left hand can not hurt people to create bloodstains, at this time, if the substitution of possibility 1, then Jane's suspicion is confirmed, because the wound can also be misled by the second wound to mislead the time of injury.

But in the case of possibility 2, the injured greedy and hidden are locked in the room, unable to come out to kill the specialty, and the rest of the people have no reason to help open the door, but Jane's words are not misleading but surrendering.

So it can only be the third possibility, the ghost is not injured, so greed, hidden, Jane, and the three are excluded.

And the cause of seizure is confirmed death, excluded.

So far, there are still suspicions: willing, hypocritical, condensing, and deceiving.

002: There are two marks on the corpse, one is the knife edge of the corpse, and the other is the strangulation mark, since the strangulation mark is a fatal injury, then there is still a mood to split the body after the strangulation, indicating that the time for committing the crime is sufficient.

It is impossible to leave such obvious flaws as kitchen knives and blood stains.

It should be mentioned here that if Zhuan's body has not been found, then there must be a hidden room in the inn, and the ghost has found this room and put Zhuan's body inside.

Therefore, deception is framed.

003: From the vomit, expression, white lips, and stiff limbs, it can be seen that it is puffer fish poisoning, and it can be seen in 005 that there is indeed puffer fish meat in the ingredients, but no one in 003 points it out, indicating that only the pseudo and murderer can identify the puffer fish meat.

The folds on the sheets are large, there are blood stains, and the only thing that can match it is the strangulation marks on the neck, that is to say, the sheets are the murder weapons that kill the specialty, and the room of the bully has two sheets, one of which must be specialized, if it is a ghost, there is no need to take out the murder weapon used before to expose yourself, because in 002, no one pointed out that the strangulation marks are fatal injuries to clarify for the deception.

Therefore, bullying is not killed by ghosts, but by people who are suspected of being ghosts, killed by people.

And in 002, there is no bloody sheet, so it can only be hidden by the ghost and the corpse of Zhuan, and the only person who can get this sheet is the hidden of Zhuan's corpse.

005's prompt said that Ning couldn't eat puffer fish raw, and it was impossible to deceive in the same way, which means that puffer fish meat is cooked food, but the key to the ingredient storage cabinet is held by Pseudo and Hidden, if someone has entered the kitchen and taken out puffer fish meat, it is impossible not to be noticed by them.

Pseudo was locked up, it was impossible to commit a crime, Ning was just sent and didn't know how to cook, so the only one who could get puffer fish meat and cook it for the bully to eat was hidden, so it was hidden and killed.

In addition, chlorine dissipates quickly, and the vents in each room cannot be closed, so it is not feasible for chlorine to kill people, so it is hidden to lie or reason wrongly

004: First of all, it is a reminder that the corpse stinks, but according to the time of Yin's death is less than 48 hours, it will not emit a large smell, only the only corpse that has not been found meets this time period, but the corpse that was hidden does not have a head, and the fake head is easy to find, but the only person who has been in close contact with the corpse has not exposed this, which proves that Ning knows that it is a person and not a ghost who made the fake corpse.

And if the corpse is specialized, then the real hidden is not actually dead, but hidden.

005: Condensation is food poisoning, there are two sources of puffer fish meat, one is the stored food cabinet, and the key to the food cabinet is in the pseudo hand and the other is in the hidden hand.

But Yin has been ruled out a long time ago, and if he appears invisibly, then it is very likely to be exposed, he is not dead yet, and Yin cannot let his fake death be in vain.

Unless Yin believes that Ning is a ghost, but if this is the case, then it is impossible to find Ning to cooperate in 004, there are no other cases between 004 and 005, and the possibility of Yin suddenly discovering that Ning is a ghost is a ghost is also very small, the only possibility is that Yin chose to kill Ning in order not to expose himself.

The second is to eat the leftover dinner plate before.

So let's say the pseudo is a ghost.

Pseudo and hidden can recognize puffer fish meat.

Then she was locked up when she was bullied and killed, which means that pseudo didn't know that anyone else could recognize puffer fish meat besides her, and only Ning knew that she was hiding and pretending to be dead, so she would never choose the most risky puffer fish meat, because if she used puffer fish meat, she would become the only suspect with motives and abilities.

But it is not excluded that as greed said, the pseudo is by deliberately exposing the reason very yourself, and conversely saying that the murderer cannot be so stupid, but so on.

The ghost can only be greedy with the key, but the problem is that greed doesn't know how to cook, this is an objective narrative, we know, but pseudo doesn't know, so in pseudo's view, deliberately exposing oneself is equivalent to one or two next, and it will definitely lose.

So the assumption is not valid.

If you assume that the pseudo is not a ghost but kills Ning, in the same way, it will be mistaken for a ghost, which is also not valid.

Greed has long been ruled out, it's not a ghost, the puffer fish meat in the ingredient cabinet is raw and can't be used, and greed doesn't know the source of the second puffer fish meat, so the murderer is not greedy.

Then there is Jane, Jane knows that Bully vomited before he died, so it is speculated that he may also know that Bully actually died of food poisoning, and Greed has seen Jane go in and out of Bully's room, and being in charge of serving food meets all the requirements for killing Ning.

Finally, let's say that the wish is a ghost.

001 Zhongwan is not injured and is eligible.

In 002, he wanted to frame the biggest threat of bullying because he picked up the murder weapon, but the evidence of the special bullying, that is, this belongs to the unpredictable category of the will, so it should be a mistake to be locked up, or deliberately use someone to kill to confuse the public.

003 was locked up. It has been proven that the murderer in 003 is not a ghost, but a person, so I am willing to make a soy sauce.

004 Zhongyin faked his death, but he didn't get close to observe Yin's corpse, so he didn't know if he was dead.

005 died of puffer fish meat, and since 003 was locked up, he didn't know that puffer fish meat existed in the ingredients, so it was even more impossible to use puffer fish meat to kill people.

To sum up, 005 is still a human killing.

And excludes the greed that doesn't know about puffer fish meat, and can't cook, and knows that it will definitely be regarded as a murderer and impossible to do it.

The murderer can only be Jane, who kills people with puffer fish meat from a deceptive plate.
