A Killer Workout

Description for A KILLER WORKOUT by Kathryn Lilley:

Welcome to Durham, North Carolina, the diet capital of the world.

After suffering yet another setback in her war on fat, plus-sized TV reporter Kate Gallagher decides that the time has come for a full-on offensive. Taking time off from Channel Twelve, she signs on for active duty at Body Blast, a boot camp-style fitness program. The regimen includes brutal exercise and bland food, and the rules are so tough that Kate's roomie, Marnie Taylor, is almost thrown out for smuggling in candy, and then again for skirting an obstacle wall during a conditioning session.

The next day Marnie is found dead at the foot of the wall, her neck broken. The campers suspect foul play, because it's not the first suspicious accident at Body Blast -- another woman recently fell to her death during a Wilderness Challenge. Kate knows that losing weight is hard, but it shouldn't be mortal combat! If someone is picking off dieters, she'd better kick her investigative skills into high gear...before she becomes a target.

This is #2 in A Fat City Mystery.
