Dead by Dawn by Paul Doiron

Maine game warden Mike Bowditch agrees to a meeting with Mariette Chamberlain, whose father-in-law died four years ago. Mariette believes that the death investigation was closed too quickly by the game service and wants Mike to take another look at the case. As Mike proceeds with his interviews on this late December day, it becomes clear that someone wants to do him harm. The big questions are who and why--and whether Mike will even survive. Dead by Dawn will be published in June.
