Mercy Dogs

For sixteen years, Ben Shepard loyally served the Long Beach Police Department. Then he took a bullet to the head, and his life was shattered. No one expects much of anything from him anymore--except his father, an old man receding into a fog of his own. And except maybe his tenant, Grace, who's been a warm and friendly constant in his and his father's bleak lives. Until the day she vanishes. After an official investigation stalls, Ben moves forward on his own. But stepping into Grace's past--and all she was hiding--is a dangerous move for a man who can't trust his memories from one day to the next. The deeper he gets, the more he has to question whether he's being driven by the gut instincts of a suspicious former cop or by paranoia. Recognizing what'sreal can save Grace's life. If only he can trust himself to do it... -- Amazon.com.
