Tally Whyte has seen a lot of dead bodies in her years with the Massachusetts Grief Assisstance Program, but this is the first time a murder victim has been brought there by the murderer himself. During the night, someone broke into the Office of the Chief Medical Examiner, aka the Grief Shop, and left behind a tragic calling card- the body of a young girl, bearing a message that reads: Sins of the Fathers. The girl's playmate is also missing. Could she be another victim? Or can Tally still save her before the k iller strikes again? As the mysteries multiply and Tally's life is threatened, she scrambles to prevent another child from falling prey to a madman's warped sense of justice.
