Looking at Kirigiri's suddenly hesitant expression, Uzuki Yuyue understood what she was thinking.

But she wasn't going to get to the bottom of it. Regarding that guy Sawada, Kirigiri would definitely explain it to her later.

Therefore, she just sighed in response to the purple girl's affirmation.

"It would be great if it were like this..."

After all, if you ask yourself, she is really just running around with a key card.

"Speaking of which, Mr. Toriyao has a doll in his room... How did he put it in the room? The size of the doll cannot pass between the iron bars."

"First, I took the doll apart, passed it through the iron railings, and then reassembled it. I took off the doll's clothes and looked at them. There were traces of splicing everywhere."

"The reason why we specially prepared such a puppet is to make us think that the prisoner has been in and out of the secret room. It is precisely because the prisoner had plenty of time that night that he deliberately arranged such a scene."

The mysteries of the two secret rooms have been solved.

The remaining question is which room window the prisoner exited through.

"Sister Kirigiri, who is the culprit?"

The core part was finally close, and May Yuyue couldn't help but ask the doubts that had been in her heart for a long time.

"Narrowing down the scope based on the conditions met will naturally determine the identity of the prisoner."

Kirigiri raised his index finger and said.

This action made May Yuyue seem to have a glimpse of the style of a little detective.

"First of all, the size of the prisoner must be relatively small so that he can pass through the narrow window. I'm afraid it's impossible for men. At least there are currently no men here who are smaller than women."

——The prisoner is female.

"Then there is the first disappearing technique. To achieve this technique, the prisoner must use the room located in the blind spot of your sight, Sister Yu, that is, the room behind '307'."

On the first night, the room was after room '307'.

"As for the window used to enter and exit the rooftop, I don't know which room it is in...but I think only one room out of ten rooms should have such a window."

"After all, if there is such a mechanism in more than one room, it may be discovered by others. Only the iron bars on the window of this specific room can be removed to let people out."

"Do you know which room this is?"

"It's very simple. The prisoner carried out murders for two consecutive days, which means that the prisoner used the room with the window mechanism for two consecutive days, right? That room is the entrance and exit to the rooftop."

People who stay in the same room for two consecutive days.

The window in that room is the secret entrance and exit.

May Yujie opened her notebook and checked the room allocation for the day.

There was only one person who stayed in the same room on the first night and the second night.

"Yes, the culprit is Ye Hezhen."

"How could it be!... It's actually that very nervous widow lady..."

She lives in Room No. 307.

It was she who strangled two men to death with her two scarred slender arms.

[It feels unbelievable...]

But at the same time, May Yuyue vaguely felt that she could do such a thing.

"Huh? Wait a minute...Isn't it just a coincidence that she stayed in Room 307? She didn't choose this room by herself."

"And sister Kirigiri, let's not talk about the second day. On the first night, we used playing cards to determine the room allocation. Ms. Yehe should not be able to choose room '307' by herself... Could it be that she moved in by chance?
