Hours before he is due to set off on a long-delayed and much-deserved vacation with his wife and son, Det.-Sgt. Malcolm Ainslie takes a phone call he would have been better off ignoring. The caller is the chaplain at Florida State Prison, delivering a message from Elroy Doil, the serial murderer Ainslie helped put on the prison's death row. On the eve of his execution, Doil has asked to make a confession. But there is a condition: he will deliver it only in person to Ainslie.

Ainslie has no choice. Doil was convicted of a double murder, but he was suspected in ten more. No homicide detective could turn down the opportunity to close ten murder cases in a single night. What Ainslie learns from the condemned man, however, propels the ex-priest-turned-cop into an investigation that reaches into the most elite levels of his own department and the Miami city government. And it tests as never before his skills as a cop and his character as a man.
