Sam Berger is accused of a murder he didn't commit, and his partner Molly Bloom lies in a coma. Sam hides on a remote lost island, awaiting instructions from security and conducting his own investigation. Meanwhile, Stockholm is under threat of a terrorist attack; a ruthless killer continues to operate at large. It’s just unclear what role Berger plays in this story. Is he the key to the solution - or the main danger? In this tense thriller, Dahl again demonstrates his skill as a storyteller and writer, showing us a shaky, unstable world where there are no guidelines and supports. Together with Sam Berger, the reader will find himself in the depths of the water, helplessly floundering and desperately trying to swim to the light.
