When Kim Prescott comes home to her Spanish villa on night, she finds a young man has moved into her home-claiming to be the brother she believed had died in an automobile accident in South Africa. The man manages to dismiss Prescotts household staff, replacing them with his own, to convince people that he is Prescotts brother and to plant seeds of doubt about Prescotts sanity... seeds that begin to grow with the local townspeople, the police and within Prescott herself in this taut thriller.
