Trouble at Moon Pass

Moon Pass was a pleasant enough place.. .until they starting putting a railroad through. Then all hell broke loose. Finally they had to call in Dan Doran, the best troubleshooter in the west. Doran was a man who knew only one way to to do the job...and his philosophy was that a singing .44 usually had the right answer. But Doran forgot one thing: it makes a difference which end of the barrel you're looking down.
