The Lawman Wore Black — Marshall Grover

Boyd was nearing the end of his career, a veteran lawman slowing down and haunted by vengeful ghosts of his violent past. Those ghosts were alive and headed for Darnell, Colorado, to settle old scores. But others were in debt to Boyd. The Texas Trouble-Shooters, Doc Beaumont and a Nebraska farmer's daughter were determined Boyd should die of old age - and they too were headed for Darnell.
