Albert Fish is a brilliant university professor. But he is also a ruthless killer incarcerated in a hospital for the criminally insane. When Fish escapes from his prison, Dr. Joseph Kallinger, the psychiatrist who testified on behalf of Fish's insanity, is called in to help profile him with Detective Van Til, the cop who originally caught Fish.
And then the videotapes start to show up. Fish is capturing distinguished college professors and debates with them. As Fish dismantles their reasoning, he proceeds to dismember his victims. Fish's murders are a forensic argument, proving himself to be guiltless and sane. Catching the killer is not enough to win this debate. Both heroes will have to face their inner demons. Cruel Logic is a story about human nature, the problem of evil, and one man's attempt to regain his sanity in a reality turned upside down.
