Shadow of the Wolf Tree (A Woods Cop Mystery)

"In the seventh installment in the acclaimed Woods Cop Mystery series, another suspenseful crime noir finds Grady Service, a detective in the Upper Peninsula for Michigan's Department of Natural Resources, back in action.  The discovery of skeletal remains sheds troubling light on an eighty-year-old cold case involving racism, gold, and murder.  Combine that with a present-day ecoterrorist whose guerrilla tactics--including a gruesome trap called a "wolf tree" --make Rambo look like a cub scout; a thriving crystal meth industry; and Service's particular brand of grizzled, sexually tense, and action-packed police work.  Death lurks behind every tree, under every rock, an within every raging river in the most action-packed Woods Cop Mystery yet."
