When Kay Norris moves into a swanky New York apartment building, she is pleasantly surprised to learn that one of the residents, Peter Hamilton, seems preternaturally attuned to her feelings. The two fall in love, and Peter reveals his secret. He owns the building and each of the apartments is wired with video cameras and listening devices, so he can sit and watch each of the residents as they live their lives. He reveals this secret to Kay, who is at first repelled, then fascinated. The building also has a dark shadow. Several of the residents have died in suicides or accidents, too many. Kay learns that Peter has killed them to preserve his secret. Now she may be Peter's target.
