Brothers In Blood

As young Stubbs 'Sunshine' Shining is riding west, he sees four gunmen firing at a homestead and scares them off. Bethany Bartok, the widowed resident, explains that her son Bart has gone off in search of his fortune, and her daughter Elspeth has travelled east to be educated. Sunshine decides to stay for a short spell - but when he learns that Bart has been kidnapped, and the local Cutaway brothers are determined to get their hands on the property, he starts to untangle threads that lead him into dangerous territory.
