The Poison Tree

Karen Clarke takes her little girl to welcome her husband Rex, who has just been released from prison after twelve years. Driving to their seaside home, Rex wants to stop and look at the house where, twelve years earlier, they lived after being introduced by Rex's extroverted, drug-taking sister Biba.

Karen resorts to desperate measures to protect her family from Rex's former cellmate, but she soon begins to suspect that he's not the only person who has tracked them down. As her paranoia grows, the truth about Biba's disappearance all those years ago comes to light.
