Back of Beyond

"Twilight falls on a cold, wet spring day in the mountains of Montana. A cabin smolders in the forest. In the remains of the kitchen, a table set for two; next door, the remains of a single body. Alerted by hikers, Detective Cody Hoyt is called to the scene. The victim is none other than his friend and AA sponsor Hank Winters, although it looks like suicide, Cody knows Hank better than that. He is convinced it is foul play. 'One of today's solid-gold, A-list, must-read writers' Lee Child."
