Hoping to shift her chances of a promotion in her favor, Evie Bloomfield heads to Mackinac Island to assist her boss’s father. Rudy Randolph has broken his leg and operating his bike shop, Rudy’s Rides, is too much to handle by himself. But Evie’s good turn only leads to more trouble. After Evie’s arrival, wealthy resident Bunny Harrington dies in what looks like a freak bike accident. Upon closer inspection, Bunny’s brakes were tampered with, and now the prime suspect in her murder is also Bunny’s number one enemy: Rudy. So if Evie hopes to stay on her boss’s good side, she’ll need to steer Rudy clear of jail. Now she must quickly solve this mystery so she can put the brakes on the real killer’s plan.
