Murat is very young when his mother and father separate. He left his father's mansion with his mother and never saw him again. However, this distance does not prevent him from suspecting his father's suicide. As far as he knows, his father is not one to commit suicide. He thinks there is a secret behind this business. The old man lost his last property, the mansion, at the gambling table where he sat for the last time before his suicide. Before he died, he wrote four names on three cards and left question marks behind. Murat will follow this clue, which he does not know what it means.
