What it's about
The story.
Your case begins on a Sunday morning: caretaker Kaya Persson lies dead in the hallway of his apartment. The door is locked, and there are no signs of a break-in. Whoever was with him must have had a key.
The police find Kaya's key ring in a man's jacket. Now he is in custody. He says someone pressed the key ring into his hand. Four people had the key ring before him, but their statements about the handovers contradict each other. Which of them holds up against the clues?
Your task: Reconstruct the path of the key ring and find out what really happened to Kaya and who did it. At 6 p.m., a judge decides whether he stays in custody.
