Backtrail — Greg Hunt

"Ridge Parkman thinks he has it all sorted out. Hang up the Colt, turn in the badge, marry the woman, and move to Missouri to breed horses. Then an assignment comes along with his name all over it. Parkman nearly dies on the western slopes of the Rockiesafter a bloody shootout with a fellow marshal gone rogue. While recuperating in a remote mining town, a kind, rough-edged woman convinces him that he'd make a fine husband, and that it's time to give up his badge. Then he gets word that Duff Joseph, a ruthless adversary from years past, in his Texas days, has killed Ray Goode, a close friend and fellow marshal. Joseph and his band are headed into Wyoming territory to sell stolen guns to the hostile Indian tribes to the north, and there is no one but Parkman anywhere close enough to try and stop him. Parkman recalls an old adage that his grandfather used to use. 'If you want to hear God laugh, make a plan'"--
