Purgatory

Jon Stanton should have been living the good life: a beautiful fiancé, a successful career, a home in paradise. But his job in Homicide has served up a bad case of insomnia and hallucinations, and just as his body, mind, and spirit are about to break, he begins investigating an intriguing series of merciless murders. As his condition deteriorates, he refuses to turn the case over to his partner, knowing he couldn't rest until justice is served. Unfortunately, justice is what the killers believe they're delivering, and their next delivery comes a little too close for comfort.
