Shadow of the Wolf Tree

Joe Heywood has a good thing going, and in his new installment, Shadow of the Wolf Tree he keeps it going.
Conservation officer Grady Service and his military buddy Tree are after a bit of r and r on the banks of a remote upper peninsula river when their tranquility is blasted by the work of what appear to be militant eco-warriors. With the discovery of two long dead bodies, the brutal murder of an out state fisherman, and the prospect of a long forgotten gold mine, Shadow of the Wolf Tree quickly catapults Service back to the front lines of environmental law and order.
After recently losing the woman he loved, Maridly Nantz, the aging woods cop now finds himself pursued by his new partner, Tuesday Friday, a new mother and a state trooper. When he figures he has the expectations worked out, he finds his perspective turned sideways, providing for some tension that is neither professional nor imagined.
Tramping through the north woods once again, Grady Service makes his way along the trail of loose ends, piecing together the clues of more than one eco-mystery.
Along for the ride are a host of regular Heywood characters, including the lovable but despicable Limpy Allerdyce, perhaps the Yoop's most notorious game violator. Back too are many of Service's allies, including Captain Lorne O'Driscoll and Simon Del Olmo.
Before its conclusion, Shadow of the Wolf Tree finds Service in typical Heywood form, angling through a messy swamp of convoluted clues, intent on once again restoring order.
