The Sacraments of Blackgum Lake - Clint Smith

Cecil Mears joins his father in repairing the old lakefront cabin where he spent his childhood. But Blackgum Lake refuses to be bucolic; its waters are dark and oppressive, holding secrets. Did the infamous gangster John Dillinger trawl the lake for something terrible? The detritus along its bottom is far more than muck. A neighbor insists her late husband comes to her door, asking to be let inside. Troubled by more than his parents' marital problems, Cecil becomes haunted by what lurks below.
