This traditional-style murder mystery takes place in the unlikely setting of a hospital where an innocuous game, which medical staff play to hone their professional skills, provides the stimulus for murder.

When Katlin's long-time friend dies mysteriously just as she is to be discharged from the hospital, Katlin and her colleague Palmer start stalking clues. Soon, they become convinced that a killer is taking advantage of the hospital environment to cover up deadly crime and using techniques that might have been learned during the game. But why would a medical professional, trained to alleviate physical and mental health, decide to murder seemingly random hospital patients? And why is this hospital the killer's target? Is the killer cold-blooded or suffering from some sort of delusion? With the whole hospital's staff as potential suspects, this whodunit is sure to keep the amateur sleuths guessing.
