In death, they are purified. Holding his victims under water, he washes away their sins as they struggle for their last breath. Then he stakes their bodies to the ground, exposing them for what they really are: witches, sent to tempt and to corrupt. No one knows about defence attorney Charlotte Wellington's murdered sister, or about her childhood spent with the carnival that's just arrived in town. For Charlotte, what's past is past. But others don't agree. And as a madman's body count rises, she and Detective Daniel Rokov are drawn into a mission that's become terrifyingly personal.
