"It seems necessary to think about why the door is sealed with rubber bands." Kirigiri walked away from the door.

"I think the key is the gap created when you push the door open like this. Sister Yui, let's not just push one side this time, try to push both doors open at the same time."

The two of them simultaneously put their weight on the two doors of the double door and pushed outward.

The gap in the center of the door has widened, almost big enough for a slim person to squeeze through, but the rubber band is blocking it at a height equivalent to the waist.

If you want to avoid it, you have to squeeze through a narrower gap, which seems to require a bit of skill.

"But this way, one thing becomes clear. There is a gap in this secret room."

As long as you find something stuck in the crack of the door, you can easily enter and leave the room.

At first glance, this secret room seems to be airtight with rubber bands, but in fact there are loopholes that can be exploited.

"But there are no footprints outside."

"Ah... like this..."

This door faces the backyard. When entering or exiting from here, you must pass through the outside. However, when they found the body, there were no traces of anyone walking in the atrium or the backyard. This was a fact that the two saw with their own eyes.

.

"Ah, but!" Yue suddenly thought of something, "What about the outer corridor? If the rubber band on the door over there is looser..."

"When we opened the door, we had to pull it open with all our strength to get the knife in. I don't think there was any way to create a gap for people to get in and out."

"Eh-...then it's really a secret room? Is this an impossible crime?"

"Who knows. The so-called impossible crime is, in the final analysis, 'a crime that feels impossible.' We just think so."

"However, as long as one person firmly believes that it is not impossible, then the illusion of an impossible crime will disappear like a bubble. We are detectives, and even if there is only one person left in the end, we must shoulder this responsibility."

Although Kyoko Kirigiri spoke simply and resolutely, it was obvious that it was impossible for ordinary detectives to have such a consciousness.

This can be seen from previous incidents.

Kyoko Kirigiri is a natural detective. At the same time, for her, detective career is everything in life. As expected, only people like her can achieve this level.

The girl was filled with emotion.

[Perhaps this is the wall that separates me from her. Being with someone like Ayan should be the most helpful to her.]

"I said, Sister Yue, let's take a look outside."

"...Well, that's true."

Although it was faster to go out through the door in front of them, the two of them didn't wear shoes, so they had to go back to the entrance first.

After leaving the murder scene, Yui and Kirigiri walked along the outer corridor to the main house.

There was a large pile of leather shoes on the concrete floor in front of the entrance, which obviously belonged to relevant police personnel. It took the two of them a lot of effort to find their own shoes among them.

Before Kirigiri picked up his own shoes, he first picked up the shoes of the first five people who came to visit and looked inside for a while.

"What are you doing?"

"Check shoe size."

Sumu 28.5

Eight ghosts 27.5

Hakushu 26.5

Duro 24.5

Shuijingshan 22.0

"You've always cared about shoe size. Is this a clue?"

"Well, this may be one of the few clues that can become a killer weapon."
