The electrifying thriller from the writers of BBC4 Swedish TV drama SEBASTIAN BERGMAN and the creator of the hugely successful series THE BRIDGE.

The massive Swedish international bestseller and the first in the Sebastian Bergman series. Now a hit BBC4 TV drama starring Rolf Lassgård, the original WALLANDER, as Bergman.

Sixteen-year-old Roger has vanished. Days pass and Västerås Police do nothing, blaming his disappearance on teenage antics. Then Roger's pale, mutilated body is found floating in a shallow marshland pool, his heart missing, and the experts descend.

They need Sebastian Bergman: widower, psychologist, top criminal profiler and one of Sweden's foremost experts on serial killers. Since losing his wife and child Sebastian has become numb to the outside world and has no interest in taking on the murder case - until he is blindsided by a secret from his past. Desperate for access to confidential police files, he agrees to join the investigation and it's not long until the brittle web of lies and deception seizes his full attention...

A page-turning, atmospheric thriller to rival Jo Nesbo, Henning Mankell and Stieg Larsson.
