The Sandman

In the fourth entry (after The Fire Witness) of the internationally best-selling "DI Joona Linna" series, the Stockholm detective finds himself facing Jurek Walter again. He arrested the psychotic serial killer 13 years ago and always suspected he had an accomplice who remained free. Joona's theory is confirmed when a long-missing victim, Mikael, is found wandering on a railroad track. He has escaped from his kidnapper whom he thinks of as the Sandman, but his twin sister Felicia is still in captivity. Jurek is smart and dangerous, but they need to get him to talk if there's any chance of finding Felicia before it's too late. Joona plans a risky strategy: Insp. Saga Bauer will go undercover as a patient in the high-security psychiatric ward where Jurek is being held and try to draw out information from him. Joona has lost his partner and his family to Jurek and will stop at nothing to end the terror.
