DI Sean Fagan investigates the ritual murder of three young women and finds links between each victim and the world's most popular computer game, Princess Kay-ling. When police high-tech units examine hard drives taken from the murder victims' PCs, traces of subliminal hypnosis are found. This induces victims to trust and obey characters from the game. These characters then order the women to remote places or use this trust to gain entry into their homes.
