Bree Taggert, a member of the Philadelphia Police Department, has spent more than twenty-five years trying to forget that terrible evening when her father killed her mother and then committed suicide, leaving Bree, her sister Erin and brother Adam orphans. But years later, terrible events repeat themselves and Bree’s sister is found murdered in her own home, and her husband, Justin, now the main suspect, disappears. Justin’s best friend, former investigator Matt Flynn, does not believe that he is capable of murder. Bree and Matt work together to find clues and gradually grow closer. Trying to find clues and track down the killer, they turn to everyone who knew the couple. But the closer Bree and Matt get to the solution, the clearer it becomes that the criminal will stop at nothing to keep his secret.
