Lorelli and Ovid Thornthwaite have been trying to kill each other for so long that they have no idea who struck first. Haunted by the tragic death of their parents, they have been raised by their servants in the isolation and sobriety of their family manor. On their sixteenth birthday, the twins agree to a truce. The arrival of the family lawyer and his son, however, turn their worlds upside down. What is the police inspector up to? Does the lawyer have another agenda? What secrets are the servants hiding? Who has broken the truce and restarted the murder attempts? And who, in the end, will be the one to walk away with the Thornthwaite Inheritance?
