Black Diamond Western #13

When greedy opportunists engineer the slaughter of Chief Thundercloud's buffalo herd to provoke an Indian war—hoping the resulting conflict will force the Army to return to Fort Junction and restore their profitable trade—it falls to Bob Vale, the Black Diamond, to uncover the conspiracy before peaceful tribes and desperate soldiers clash. Sent by General Whitcomb himself, Black Diamond must track down the real culprits and convince Thundercloud to hold back his warriors, all within two days before the frontier erupts into bloodshed. With his horse Reliapon at his side and his reputation with the tribes on the line, the marshal races against time to expose the sinister plot and prevent the Buffalo War.

Sheriff Coriolanus Thorpe arrives in Sundown Valley as the first lawman the frontier settlement has ever seen, only to find the town on the brink of open warfare between cattle ranchers and sheepmen led by Jim Scottsbury and his brothers. With his unconventional manner and unorthodox gunmanship, Thorpe must navigate both sides of a brutal range conflict while trying to restore order before the valley tears itself apart. His courage and quick thinking will be tested as violence escalates and the line between justice and survival grows dangerously thin.
