On an ordinary spring day, Special Agent Faith Mitchell of the Georgia Bureau of Investigation returns home to a nightmare. Expecting to find her mother minding her daughter Emma, she is horrified to discover Emma locked in the shed and a trail of blood to the front door. The house has been torn apart and a man lies dead in a pool of blood. She stumbles across two more intruders, and within minutes they too are shot dead. And when the Atlanta police force turns up, Faith has some difficult questions to answer. But she has some desperate questions of her own. With Faith suspended from duty, Will, together with the help of Dr Sara Linton, must piece together the fragments of a brutal and complicated case – and catch a deeply troubled and vicious murderer.
