A headless mystery writer is found in a locked room that no one could have left without leaving the door unlocked. When the room is broken into, there is no head, no weapon, and no murderer. The only way the killer could have left the room is through the door that has just been forced open. And the late decapitated mystery writer, George Zimaresh, has left a note with cryptic clues for Dr. Imogene Chaplin, the pathologist on the scene. The only problem is that Chaplin didn't know Zimaresh, and Zimaresh couldn't have known her. And yet... It's not enough that Imogene Chaplin is a diagnostic pathologist who doesn't like doing autopsies or forensics. She is only doing this job on a temporary basis, . Now she is sucked into this investigation. She must solve this apparently impossible murder before she ends up being a victim herself.
