If you refuse to believe me, I will no longer consider you my son.

Daniel believed that his parents were enjoying a peaceful retirement on a remote farm in Sweden. But with a single phone call, everything changes.

Your mother...she's not well, his father tells him. She's been imagining things - terrible, terrible things. She's had a psychotic breakdown, and been committed to a mental hospital.

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.

Caught between his parents, and unsure of who to believe or trust, Daniel becomes his mother's unwilling judge and jury as she tells him an urgent tale of secrets, of lies, of a crime and a conspiracy that implicates his own father.
