Gray Ghost

Seven years ago, Stoney Calhoun woke up in a VA hospital with no memories. He still remembers nothing from before then, except that he has a few unexplained skills—a gift for angling, an ability to read French—and recently it's been made clear to him that it would be best if he never does.
Working as a guide on Casco Bay, Maine, Stoney is out with a client on an early morning fly fishing expedition when they find the charred remains of a recent corpse on a small, uninhabited island. A couple of days later, Calhoun's client turns up in the driveway of Stoney's cabin in the woods—shot dead in the front seat of his SUV.
In the midst of a couple of inexplicable murders, both of which clearly have something to do with Stoney, past or present, it's up to him find out the truth...or risk becoming the next victim.
