The Traveling Undertaker — J.R. Roberts

Traveling through Wyoming Clint Adams encounters a man in a huge wagon, being drawn by two Clydesdales. The diminutive Brit is accosted in a saloon, and after Clint steps in to save him, the man asks Clint to join him on what is a new business venture. He tells Clint that he is a traveling undertaker. Although he's dubious about the undertaking, Clint agrees to travel for a short time with the man, to see just what he does. As it turns out, something else is going on, and after they part ways, Clint must find out what that something is--if he can stay alive to do it.
