Trespasser by Paul Doiron

Young Maine game warden Mike Bowditch is called to a car/deer accident, but when he arrives the female driver has disappeared. Despite having a bad feeling about the situation, Bowditch hands the case over to state trooper Curt Hutchins. The next morning, though, he decides to try and find the driver, Ashley Kim. That evening, Bowditch and his friend, retired warden Charley Stevens, discover her dead. The manner in which Ashley was murdered is eerily similar to the death of another woman, Nikki Donnatelli, who died seven years ago. Her killer, Erland Jefferts, is in prison. But some believe Jefferts is innocent and have been petitioning for his release. With a myriad of suspects and questions about whether there is one killer or two, Bowditch cannot stop trying to uncover the truth-- even though it's not his job and despite the toll it takes on him. In Trespasser, Doiron has succeeded in writing a mystery that's even better than the first (I was definitely lukewarm about The Poacher's Son). I'm anxious to continue with Bowditch on his journey through rugged Maine. For people who enjoy C.J. Box, Steve Hamilton, and William Kent Krueger.
