Year: 1972. ISBN: 0671212826. A new novel of suspense by the author of ""Psycho."" The money it took to become a patient in Dr. Griswold's private sanatorium bought anonymity first and then treatment. Even after the doctor and staff are hideously murdered and five patients escape to terrorize the plush San Fernando Valley, no one is willing to reveal names. But when three of the missing patients are also viciously slain, Karen Raymond must act. For her own husband is either the ruthless killer bent on destroying all who know him-including herself-or the next most likely victim.
