Watch THE CALENDAR KILLER on Amazon Prime now - a gripping adaptation of Sebastian Fitzek's bestselling novel WALK ME HOME.

A missing child. A desperate father. A terrible secret.

Guido T has already confessed to two horrific child murders. Berlin police are sure he also murdered six-year-old Max, who disappeared without a trace a year ago.

But now the killer is staying silent. Without any certainty, Max's parents are unable to say goodbye to their son.

Everything changes when one investigator makes an unbelievable offer: he can place Max's father, as a fake patient, inside the maximum security psychiatric hospital where Guido T is imprisoned.

Max's father agrees. He plans to force the child killer into a confession. Because nothing is worse than uncertainty.

Or so he thinks.

international bestselling author Sebastian Fitzek sends you on an ingeniously disturbing journey with THE INMATE. Perfect for fans of John Marrs and Chris Carter.
