It's being released soon, according to the William Gay Archive and I think many of you will be interested. Here's the description.
John Stoneburner, a jaded detective, has abandoned his office in Memphis to live on the banks of the Tennessee River. There he meets retired sheriff, Cap Holder, who made a small fortune after Hollywood produced a movie based on his exploits cleaning up the drug dealers in his rural county. Holder hires Stoneburner to hunt down his young girlfriend and a suitcase full of drug money after they disappeared at the same time. The investigation brings Stoneburner in contact with a figure from his youth, Thibodeaux, now an unpredictable town drunk. Enslaved to their past indeed, the intertwined trajectories and motives of Stoneburner, Holder, Thibodeaux and the young woman eventually collide in a crazed chase across Tennessee, Mississippi, Alabama, and Arkansas.
It's out of stock at Amazon right now because of last-minute changes, I've heard, but will be available again soon.
