Tony Hill has had a good run. He and detective Carol Jordan have put away scores of dangerous criminals at a rate that colleagues envy. But there is one serial killer who has shaped and defined their careers, and whose evil surpasses all others: Jacko Vance, ex-celebrity and sociopath whose brilliance and utter lack of remorse have never left Tony's mind in the ten years since his imprisonment. Now Jacko has escaped from prison and is even more twisted and cunning than before. He is focused on wreaking revenge on Tony and Carol for his years spent in prison. Tony and Carol don't know when Jacko will strike, or where. All they know is that Jacko will cause them to feel fear like they've never known.
