Everyone has secrets. Some of them may kill you.

When a Delaware real estate mogul is murdered, newspaper journalist Brian Wilder wants the scoop on the killing, including the meaning behind the mysterious loaf of bread left with the corpse. Reverend Candice Miller, called to minister to the grieving family, quickly realizes that the killer has adopted the symbolism of sin eating, a Victorian-era religious ritual, as a calling card. Is it the work of a religious fanatic set to punish people for their missteps, or something even more sinister?

As more victims fall, Brian and Candice follow a trail of deceit and blackmail, hoping to discover the identity of the killer-and praying that their own sins won't catch the killer's attention.
