No sooner has Montana become a state than Zimmerman launches a diabolical campaign to turn a remote swath of land into an outlaw kingdom. Some of the richest mines in the West are in Zimmerman's sights, and he's rallied allies on both sides of the law to stake his claim.

The corpses are piled high in Halstead's war with the vicious outlaw, but now Zimmerman proves himself as cunning with a pen as he is deadly with a six-gun. When news of his plot reaches the state capital of Helena, U.S. Marshal Aaron Mackey and Deputy Billy Sunday step into the fray.

Halstead is taking no prisoners to prevent Zimmerman from getting filthy rich off land bought with dollars . . . and soaked in blood . . .
