Head Case was nominated for the 2022 Shamus Best PI Novel award. Chicago private investigator Sam Kelson uncovers more than he bargained for when he investigates a series of suspicious deaths at the Clement Memorial Hospital. "My friend, this place is killing people." While in the hospital recuperating from a gunshot wound, Chicago PI Sam Kelson is approached by a nurse who's troubled by three recent deaths. No pattern, no connection - except that three patients died when they shouldn't have. Initially skeptical, Kelson starts asking questions - and the more he uncovers, the clearer it becomes that something isn't right. What exactly has been going on at Clement Memorial Hospital? Has someone been killing patients? If so, why? As Kelson digs deeper, he comes to realize that someone is determined to prevent him finding out the truth. Whatever it takes.
