Murat was very young when his parents separated. 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 the type of person who would commit suicide. He believes there is a secret behind this. The old man, before his suicide, had lost his mansion—his last remaining asset—at the gambling table where he sat for the last time. Before dying, he wrote four names on three gambling cards, leaving behind unanswered questions. Murat will set out to uncover the meaning of this clue, whose significance he does not yet understand.
