"Died from being pierced through the chest, the murder weapon was the big iron nail, the murderer nailed her directly to the door, the lung lobes and stomach leaked, and the death was very painful." Grageson pointed to the nail in the deceased's chest and said, "Then the murderer nailed her hands and feet to the door as well, but the door was so narrow that one of the limbs was nailed directly to the wall."

That's the obvious situation

Oh, I think it should be emphasized that the door to this room is still locked, the key is hanging around the neck of the deceased, and there is no window in the whole room, of course, such an old building, there can't be any secret passages or anything like that, the only way to enter and exit the room is this door. ”

Gregson's description of the murder scene is not like Hopkins, he just said the most critical points once, and then spread his hands very weakly:

"So, how did the murderer get out after all of this?"

Sherlock didn't answer the question, but walked over to the corpse, then lifted up one of his drooping arms and looked carefully at the large hole in his hand that had been pierced by nails:

"I'm more concerned than how the murderer gets out, if the deceased is nailed to the other side of the door, then how do you get in?"

"Kick it open." Gregerson said very simply and directly: "At that time, in order to find the deceased, we traced all the way to this building, caught a few homeless people in the building, and asked if anything unusual happened in this building in the past few days?

The homeless people said that something was wrong with one of the innermost rooms on the seventh floor, and a large nail had poked out of the door.

However, the people who live here are all poor people at the bottom of the city, as well as a large number of addicts who have some brain problems due to the use of hallucinogens, so there is a big nail on the door, maybe someone sucked high, and the people in this building have not been careful.

Then, I came with a ticket of people, and when I knocked on the door and there was no response, of course I kicked the door open. ”

Sherlock nodded, admiring this almost unreasonable style of handling cases.

"So, you only saw this corpse after you kicked it open, right?"

“.” Gregerson frowned, not quite understanding what Sherlock meant, but nodded anyway.

He thinks this is nonsense, because there is no one here who can 'see through the wall', of course, he only sees the corpse after opening the door, besides, as long as the murder happens indoors, don't they all see the corpse after opening the door?

Sherlock seemed satisfied when he saw the other man's affirmative nod, then turned his head and shook the door a few times.

In fact, this is a very old wooden door, which is estimated to date back to before the second demonic invasion, and after more than 30 years of decay, as well as the perennial fog and damp erosion of the city of London, the upper and lower edges of the wooden door have retracted slightly, resulting in a gap of a few millimeters between the door frame and the doorframe. Fortunately, the position of the door lock has not changed with the years, which makes this door still have the function of [only with a key, can the door be locked outside].

But the key is hung on the chest of the deceased, and the deceased is nailed behind the door panel, that is, it is not only a secret room, but also a double secret room. Unless the murderer can crush himself into a meatloaf less than half a centimeter wide and get through the crack in the door, no one will be able to get in, let alone get out.

It was late at night, and in the courtyard of Nightingale's villa, in the makeshift barracks, Hopkins's mood became more and more anxious.

The body of the stage actor had been found, but he did not follow it, for the safety of Miss Nightingale was more important than these people, and he had to keep watch over it.

After midnight, the day is over.

In two days, Nightingale will face an imminent murder, and no one knows what form her murder will take, let alone how it should be avoided.

Sealed rooms don't work.

You can't hide in a place where no one knows.

In fact, Hopkins had thought about recruiting a group of third-order combatant contractors from the Adjudication Division to surround Nightingale, so that people would not be murdered.

But I thought about it again, this way of guarding is not a disguised convenience for the Ripper, in case he blends in with these contractors, that stretch out his hand, he can kill Miss Nightingale, and at that time, he will not become a sinner for the ages.

The more I thought about it, the more annoyed I became, the more anxious I became, and I subconsciously wanted to pick up the coffee at hand and take a sip, but I found that the coffee cup was already empty.

He was about to call Natasha to pour herself another glass.

The barracks curtain was lifted, and Sherlock, Watson, and Gregerson walked into the makeshift office.

"You're going pretty fast." He said with some confusion.

"The room is very small, just like a coffin, and the process of collecting evidence is handed over to the people below to deal with, and we will come back." Gregerson let himself sink into the sofa tiredly, and then threw a folder on the desk: "Inside is the scene photo I just took, if you think you haven't been exhausted so soon, you can take a look and help think about how the murderer disappeared out of thin air after killing someone." ”

Hopkins picked up the file bag on the table, pulled out the photos inside, and looked at them one by one. The investigators of these royal investigation teams are quite professional, and each photo is even affixed with a small note with annotations, so that even if you don't go to the scene of the crime, you can roughly piece together the situation of the crime scene.

Of course, after looking at it for a while, he threw the picture on the table in frustration and leaned back in his chair. It can be seen that the previous case has brought his energy to the brink of collapse, and he can't support it at all when he studies this new case.

That's when it happened

"Well, something suddenly occurred to me." Without warning, Sherlock turned his head, looked at Hopkins and asked, "I remember, you said the other day that the Inquisition was escorting a man who was about to be murdered on the list on a steam train to transport him to a safer place, and you were sitting across from his seat.

But in the process, passing by a lake, you are shaken by the light reflected by the setting sun.

In less than half a second, you subconsciously close your eyes and open them again. The throat of the person in front of him was cut. ”

Hopkins didn't know why Sherlock asked the question out of the blue, but he nodded in response, "yes, right in front of me, the murder was done in an instant." ”

"I still remember when you said that there were six other heavily armed soldiers in the carriage at that time."

"Yes, although everyone thinks that on the high-speed train, the ripper should not sneak in quietly, but some people are still arranged to keep an eye on the carriage, and even in the two carriages in front and behind, there are some deacons from the adjudication department squatting, in case the murderer really appears, it will be just right to capture him."

Sherlock listened to the account he had heard on the first day, and slowly lit a cigarette: "Maybe I forgot, but you don't seem to have said that you were going to transport this dead man from where." ”

"I don't know if you remember the results of the Darwin resuscitation experiment when you participated in the Darwin resuscitation experiment."

"Oh, that's where it is, it's safer than in the city of London." Sherlock muttered to himself, then threw the cigarette butt on the ground and stepped on it, "So, did you find a strange problem?" ”

This understatement made several other people in the office stunned: "What problem?" ”

Several people asked almost in unison.

"That's it. Ripper, his killing habits seem to be changing all the time."
