A dark and twisted early thriller from the dark master of suspense, Alex North Every year Detective David Groves receives a birthday card for his son - even though he buried him years ago. His son's murder took everything from him, apart from his belief in the law, even though the killers were never found. This year, though, the card bears a different message- I know who did it. Meanwhile, a woman who died in a car accident is claiming to be back from the dead - with a terrifying account of what she's been through. The answer to both lies with the kind of people you want to run from - and uncovering the truth means going through hell . . .
