Strange Houses 1

A writer specializing in the paranormal receives a seemingly ordinary floor plan, but when his architect friend analyzes it, they perceive a strange space. What secrets does this house hold? Who might have lived there? Why would anyone design a house like this? What purpose could a room that no one can access serve? Through interviews, reconstructed floor plans, and chilling theories, the reader is drawn into an uncomfortable truth: someone has been designing houses to hide things… or people.
