In this nightmarish tale, a third-rate detective is faced with an impossible crime, as bodies are turning up without their brains and without any indication of how the organs were removed. His only lead—an attractive landlady—becomes more than a lead and drives him into a world of terror, where his sanity is questioned and he must stop the monster before she does more evil. Or should he join her? Does he even have a choice, or will he just be driven by terror?
