Ben Harris's sister died of cervical cancer more than three years ago... his best friend and her husband, Roger Keswick, disappeared the day before the funeral. For the next six months everyone from the local police to the Department of Defense searched for him but to no avail... it was as if he had simply fallen off the face of the planet only to reappear at work as if nothing were out of the ordinary.
Then by the purest of coincidences Ben finds himself pulled back into Roger's life only to discover he has remarried... to Jessica... a woman the looks, sounds and acts just like his dead sister. To complicate things Roger is insistent his home, his car, his life is infested with tiny elf like creatures he calls the Katoy. He claims they run massive machines under his house and watch his every move... every move that is until Jessica is found bludgeoned to death in his living room and Roger is nowhere to found . . . again.
