Justice of the Mountain Man — William W. Johnstone

IT TAKES A TOUGH MAN TO PUT SMOKE JENSEN BEHIND BARS...
On the Western frontier there was no lawman more feared and respected than U.S. Marshal Bill Tilghman. But now Tilghman has found the body of a man left outside a Texas saloon. And with more than a strong hunch who the killer was, Tilghman starts tracking down a man just as legendary as he is: Smoke Jensen, Mountain Man.

Jensen was drawn into a fist fight by a slick-talking thief named the Durango Kid. But when Jensen walked away, nobody was dead. It isn't long, though, before Tilghman has the Mountain Man arrested for the murder of one of Durango's gang and headed for a hanging judge in Arkansas. That's when Smoke knows that, legend or no legend, he's going to have to bust out of Tilghman's jail, hunt down the Durango Kid, and find the truth behind a brutal murder. But there are two things Smoke never counted on: saving Marshal Bill Tilghman's life -- and fighting him again.
