[3] Josy, the twelve-year-old daughter of the renowned psychiatrist Viktor Larenz, seems to have disappeared without trace after one of her numerous visits to the doctor.
The investigations remain unsuccessful, Larenz and his wife Isabell live for years without any sign of life from their daughter.
Four years later, Larenz, who is no longer practicing, agrees to an interview in order to come to terms with the past and retreats to the island of Parkum.
At first reluctantly, Larenz begins therapy when Anna tells him about her illness: She is a writer and suffers from schizophrenia; all her novel characters manifest themselves in her life.
Since his collapse, he has indeed been in a psychiatric hospital as a seriously ill person without interruption, and in conversation with a doctor he experiences this bright moment, which at the same time serves as a confession of murder.
Subsequent investigations reveal that Isabell, out of greed, framed her sick, wealthy husband for the murder of Josy, and later went into hiding with her daughter who was thought to be dead.
