Charles Willeford: The Difference (UK 2001)

From the Publisher:
Set against the sweeping panorama of Arizona circa 1880, this work has many of the surface trappings of a standard western. However, from the first shocking realisation that the line between good and evil is being overstepped, the author then begins to dismantle the American cowboy myth.
