Evan Miller is a member of, and provides security for, an exclusive, adults-only swingers' club. When he discovers a woman, badly beaten and unconscious in a private room, he must identify and apprehend her attacker before he escapes. But how do you find one man among scores in a building full of people focused on their own pleasures? The club is crowded, most members are too involved in their own affairs to be of any use as witnesses. They also value their anonymity and won't appreciate being questioned. Worse still, he has no idea who he's looking for—but Evan is not going to let him get away with it.
