Gray Ghost — William G. Tapply

Stoney Calhoun is a man without a past. Still, pieces of lost memory seem to tantalize his daily life since a freak accident wiped his slate clean. Now part owner of a Portland bait-and-tackle shop, it's just another morning out fishing with a customer when he comes upon a blackened, charred corpse. Soon after, the man who found the body with him is murdered. Stoney suspects his missing past is the reason. But why?

The identity of the torched body turns out to be that of a convicted child molester. And what's missing in Stoney's memory is made up for by survival instincts honed by years as a seasoned cop. As he starts probing the double murder, he rediscovers a profoundly useful skill for going one-on-one against a determined killer.
