He closed his eyes, counted to himself for fifteen seconds, then opened his eyes and pointed at the robber's shoes.

"You have mud on your shoes."

“But it didn’t rain today.”

"That means you came from near the riverbank."

"Look at what you are wearing. They are high rain boots specially used to block mud and sand, and they are stained with a lot of dust..."

"When you fired the gun just now, your hands were steady and your arms were extremely strong."

8

"If your back is unnaturally hunched, it means you are doing a job that requires you to bend over all the time."

7

"There happens to be an engineering team near the river. Considering the above reasons, you should be a member of the team."

Sakaki Makoto raised his lips and said, "And he is the worker responsible for piling."

5

The robber's body trembled, and a look of horror appeared in his eyes.

4

“You…you…”

3

He never expected that there was such a hidden talent in such a small business hall.

2

He stood in front of Sakaki Makoto, feeling a sense of fear that he had nowhere to hide.

The smoke alarm was activated.

The sound of the fire alarm drowned out the police bells, urging everyone to take shelter, while a semicircular curtain of water sprayed overhead.

The ground soon became wet.

Of course there was no fire in the mall, and the smoke alarm was activated because of the wet cigarette in Makoto Sakaki's hand.

Sakaki Makoto casually tore off a flyer, wrapped the wet cigarette butt in it, and threw it into the trash can.

Then he said:

"do not be afraid."

“This is the fifth floor of the mall.”

"According to the police's habit, they will come from both the elevator and the stairs."

"This will take two minutes."

"You have thirty seconds to escape through the emergency exit."

Sakaki put his hands in his pockets and smiled: "Want to run?"

"Or should we stay here, take hostages, and fight the police to the death?"

Is it still worth thinking about it?

The robber turned around and ran away without saying a word.

The smooth ceramic floor was full of water. Rain boots should be non-slip....

But the mud under his feet was melted by the accumulated water, greatly reducing the coefficient of friction between the two.

So....

Swish!

Under the dull gaze of the crowd, the robber fell heavily to the ground.

The pistol slid out and was firmly held by a foot.

"Arrest him!"

The policemen rushing out of the elevator rushed forward and knocked down the robber who had just stood up.

Megure Juzo arrived "just in time" with the police.
