you investigated the case, your detective Koenig told about Fischer who killed children. this investigation has been going on for more than a month, but there are no results.
After a while you were walking with Koenig in the park, it was already quite dark. You sat down on a bench, discussing something. And suddenly the topic turned to Fischer. Koenig noticeably fell silent and spoke lightly about him, changing his position, he took out a cigarette and lit it. Silence fell.
After a couple of minutes he said.
— I can’t tell anyone, but I can’t remain silent either.
he mumbled, exhaling smoke from his cigarette.

• I didn't see Fisher, I invented him. I wanted to be a detective.
  he said and looked at you, after a pause you answered.
• Fuck..

After a while the murders were repeated. One cloudy day, when Koenig burst into the office with a pistol, all wet, a grin played on his face as he looked at everyone and stopped at you.
— have you heard about Fischer?)
Everyone nodded slowly, looking at Koenig with distrust.

• Well, here it is, it's me.)
  he said and pointed the gun at one of the detectives.
