Seeing this, the old Kohler next to him whispered:

"So you're a detective."

He said as he took out a few pieces of paper from his inner pocket of his clothes and spread it on the table in the cafe.

Klein glanced:

"This is too troublesome. I think it can be divided by location. Better apartments, apartments with five or six people crowded together, corners of the street shelter, benches in the park, bars, and workhouses."

“In addition, you can divide work hours and rest hours.”

Mike listened carefully and nodded:
