A professor of abnormal psychology, Jeffrey Clayton struggles with a dark past. Twenty-five years before, Jeffrey and his mother and sister fled his tyrannical father - a man who was later suspected in the heinous murder of a young student. Though the father was never charged, he committed suicide. Or so it seemed. Since then Jeffrey's mother and his sister, Susan, have concealed themselves in the remote tangled swamps of the Upper Keys, where Susan creates word games for Miami Magazine. But someone has sent her a cryptic note. Once deciphered, it carries a terrifying message: I have found you. At the same time, a serial killer has invaded a community whose citizens seek a haven of old-fashioned values. And one new-fashioned guarantee: unconditional safety. But no one is safe from this intruder - who murders young girls in unspeakable ways. Is Jeffrey Clayton's father the source of this latest killing spree? The authorities think so - and they present Jeffrey with an ultimatum: Find the butcher responsible for the newborn spate of carnage. Find your father.
