With her career in tatters and her marriage receding in the rear-view mirror, ex-RCMP corporal Lacey McCrae trades her uniform for a tool belt and the Lower Mainland for the foothills west of Calgary. Amid the oil barons, hockey stars, and other high rollers living in the wilderness playground is her old university roommate, Dee Phillips. Dee's glossy life was shattered by a reckless driver. Now she's haunted by a nighttime prowler only she can hear. As snowmelt swells the Elbow River, threatening to close the only bridge back to civilization, Lacey must control her fears and find out who has reason to want Dee silenced. A missing hockey player and the strange behaviour of the neighbours throws shadows of doubt on several locals. But just when Lacey starts to put the pieces together, it seems that she may be putting a target on her own back. Someone has a secret, and they'll go to great lengths to ensure it is never revealed.
