Boneflower

A bachelor party camping trip takes an unexpected turn when the participants discover they are sharing their mountain campsite with a skeleton – a biologist who was murdered three decades earlier. Glen Russell had been on the trail of some extremely rare flowers, and someone was determined he shouldn't find them.
As the R&P staff – Rob, Phil, Ellis, Virginia and Mitch – are reluctantly drawn into the ensuing homicide investigation, witness after witness disappears, reputations are smeared and they begin to wonder if some things would be better left buried.
