"No, there is another possibility..."

Sakaki Makoto raised his head and spoke in a cold voice:

"The criminal strangled Takenaka Momoe to death in the water."

“Why do you do this?”

"The hot spring water in the hotel is in a flowing state and is completely replaced every 20 minutes on average. If you want to strangle someone to death, it is possible that there will be signs of life, which are the so-called signs of struggle. This is an important basis for the police to solve the case."

After a pause, Sakaki Makoto added:

"But if the victim is strangled in running water, the victim usually has no chance to leave obvious signs of struggle. Even if the victim is incontinent due to suffocation at the time of death, the water will wash it away. It can also prevent the victim from struggling in the dying state and leaving scratches and other evidence for the criminals."

"Scratches?"

Kidd was still a little confused:

"You can't struggle in the water?"

“You can struggle in a river or the sea, but a flowing hot spring is different.”

Shaking his head, Sakaki Makoto replied:

"The mobile hot spring has a water outlet. The criminal can wrap the rope around the outlet to form a lever, wrap one end around the neck of the deceased, push her into the water, and then pull the other end of the rope. In this way, the crime can be committed without contact."

"This was a premeditated murder. The perpetrator was an experienced killer who would not leave any traces."

Kidd constructed the scene of the crime in his mind. The murderer stood at the edge of the hot spring, holding the rope tightly, and watched coldly as Takenaka Momoe struggled desperately at the bottom of the pool. Finally, she lost her strength bit by bit and drowned in front of him.

"This... this is too cruel..."
