There Was Only One Way Out For Shirley
From the back:
When she made an amorous tryst with her handsome young boss at his secluded country estate, pretty Shirley Grey didn’t know he had just slaughtered a man in cold blood.But when he turned her over to sadistic Willard Keep and corrupt Vicky Darracott — plus a man with a whip — Shirley realized she, too, was marked for evil. And when she escaped with Jason, a daredevil adventurer up to his neck in international espionage, Shirley knew she had gone too far –and it was too late to turn back!
