Three O'Clock's Dark Night. The Number Mysteries

A simple camping trip turns into a nightmare when a dying man taps repetitively on the side of the motor home next door to Samantha Blackwell and her husband. Sam is convinced that the tapping is a message, some kind of code, left by the victim. When the local minister tells her in confidence that he was supposed to meet the victim and had, in fact, been there when the man was murdered, he pleads for her help. What can Sam do? Her friend is in trouble. To observe one of the suspects, Sam disguises herself as a biker mama and enters the depraved depths of the Pigpen, the most infamous biker bar in southern New Hampshire. Disguising herself as a biker mama, she enters the depraved depths of the infamous Pigpen. Before the evening is through, she is challenged by her fear and the roomful of angry, tattooed bikers. Sam escapes from the bar at midnight, and is chased through the back roads of New Hampshire by a shadowy figure on a Harley? in a car? She can't tell which, as her speedometer hits seventy miles-an-hour. Sam has to wonder if her loyalties and curiosity are finally going to be the end of her.
