From the author of Child 44, soon to be a major film starring Tom Hardy, Noomi Rapace and Gary Oldman, comes an intricately-knitted thriller in the vein of John Le Carre's APerfect Spy.

Daniel believed that his parents were enjoying a peaceful retirement on a remote farm in Sweden, the country of his mother's birth. But with a single phone call, everything changes.

Before Daniel can board a plane to Sweden, his mother calls: Everything that man has told you is a lie. I'm not mad... I need the police... Meet me at Heathrow.

Presented with a horrific crime, a conspiracy that implicates his own father, Daniel must examine the evidence and decide: who is telling the truth, his mother or his father? And he has secrets of his own that for too long he has kept hidden...
