The Midway, a halfway house for convalescing mental patients where someone is setting nasty little traps that may prove fatal. It seems simple enough at first, just come as a new patient, be one of twenty-five, and then put it all together, stop the "accidents" and go home. So simple, but...five minutes after arriving Mitch Tobin is tripped at the head of a flight of stairs, leaving him with a broken arm, a headache, and no idea of where to begin. His first two clues aren't helpful, the Director's assistant seems to spend his time antagonizing the patients and one of the patients only appears in the early morning hours...and isn't registered. Then the fire escape collapses and the dirty game becomes murder! Now Tobin is responsible for two deaths and the pressure mounts.
