From the back of the book...
From 9 to 5, she is Fay Colby. A sedate and successful advertising executive.
After hours, she is Ann Decker. A sensually insatiable woman with a compulsive hunger for four ver different men-and a taste for the dangerous borderline that wavers between emotional control and sexual abandon.
But someone unknown to Fay, yet very close to her, is about to envelop her in terror...striking murderously at the men in her double life...standing poised to take her...in the ultimate possession of body and soul.
