Gun Gentlemen, by Max Brand (epub/Kindle)
Lucky Bill’s good fortune has just about run out. For as long as anyone can remember, the ornery dude has led a charmed life, but someone has framed him for a hanging offense. He’s wanted by every tin star in the West and by every greedy gunslinger out for the price they can get for his no-good corpse. But Bill is no yellowbelly—he’s aiming to clear his name and he’ll take on any bushwhacker who stands in his way.
