"Detective David Wolf's slow winter in the Colorado Rockies is interrupted by two events: a mountain lion attack in a remote trailer park, and a wealthy man coming into headquarters to report the robbery of three valuable paintings. Leaving the big cat incident to animal control, Wolf follows his duty and pursues the two thieves, even if the victim is a cagey billionaire with his hands in the pockets of an equally shady newcomer in town running for sheriff. The investigation starts off slow, crawling to a halt as the winter ends. But as summer heats up, bones are discovered in a local abandoned mine, and it turns out the story Wolf and his team has been fed is more complicated, and deadlier, than originally thought. Killers are near and in plain sight. It's just a matter of figuring out who. And why?"-- From publisher's description.
