Who Killed Mr. Cartwheel?

Burke goes cowboy at a tourist-style Old West town, after the hanging of Emerson Cartwheel at a coin auction. The clue is a valuable rare coin used to kill the victim, but before Burke can investigate, he's tossed in the hoosegow by the local honorary (and very lovely) female sheriff of Epitaph Flats. After a dramatic jail break, with an assist from Henry, Burke and his crew question the town drunk, one of the ""gunslingers"" in the Wild West tourist show, the victim's business rival, the lady blacksmith and a very Brooklynese ""Native American"". Soon real bullets start flying and the whole case ends in a barroom free-for-all.
