[Scene of the crime: Subject A has obvious strangulation marks on his neck, a room key to 1081 hanging from his waist, the water on the table contains sleeping pills, a pen under the sofa, and a small amount of breadcrumbs under the corpse. 】

[Survey Results:

A: The owner of a company of the deceased's husband was very fond of drawing, and he and B are currently in a state of divorce, before that, he said that he had been staying at 1018, and it did not take two minutes from the time K went to the front desk to get the pen to the time he came back. 】

[C: A's employee was in room 1017 and had no special hobbies, and was publicly humiliated by B in the company before, and found a matching room 1081 in his room drawer, the key matched the key on the deceased's waist, claiming that he was having breakfast in the restaurant at the time of the crime. No one has proven it. 】

[D:A's employee is in room 1082, and he likes to draw very much, and he is also having an affair with B, but he has been getting into a lot of trouble lately.] Because B often uses fame to blackmail D not to leave her. Found a bottle of sleeping pills under the couch in room D. Claims to be drawing in the room at the time, and it was A. No one has proven it. 】

[Hotel surveillance has been broken for a long time, so no one knows who got into B's room.]

Who is the murderer? What was the modus operandi? What is the flaw? Come on, detectives!

[PS: Dear detective, don't try to quit the little dark room, you can try it.] It cannot be scribbled, and it is detected by professionals. If you really can't write, press the back button in the bottom right corner, and you'll be automatically exited from the test. You will be ordered to abstain. 】

[And each test detective case is different, so you can only rely on yourself to solve the case.] 】

[Come on, dear detective!] 】

Strings of words appear on the interface.

It's like a complicated magic book.

After Xu Qing finished reading everything, he was silent for a while.

OK, the latter means that she can't check on Baidu, she can't ask others, she can only rely on herself.

She understood.

She looked at her phone screen and half rang.

Room key for 1081.

Hypnotic drugs in a glass of water.

Bread crumbs on the table with pens under the table.

Pen......

Strangulation ......

That proves the preliminary judgment that it was not a suicide death, but homicide.

When K and A first met, Mr. A was drawing. Pen in hand.

Another employee of Mr. A's company, Ms. B, had an affair. When Ms. B was killed by the others, he was also drawing with a pen in his hand.

What is the relationship between the two?

And the rooms of these two employees are so close to each other.

Is there a coincidence?

Or is it deliberate?

K said that it took less than two minutes when he took the pen and came back, so Mr. A can preliminarily judge that his wife was not killed by A.

So the key suspect was on two of Mr. B's employees.

One is an affair with his wife, and the other is an employee with whom he has a personal vendetta.

Among Mr. A's two employees, his wife's affair also said that she had been in trouble recently, and often used her reputation to blackmail D not to leave B.

Plus a paintbrush and a bottle of sleeping pills.

D can be said to be the key suspect.

Plus a series of pushes.

Xu Qing understood!

She sends answers by typing on her phone.

[I think: First of all, the order of the hotel number is unreasonable. So I think the hotel number was reversed, and the evidence is that k fell under the sofa in room 1018 of A. 】

[My reasoning: First of all, A has been with K all the time, and it was only 2 minutes before K went to get the pen, so he had an alibi (premise: the autopsy's time of death was when A and K were together)].
