The Stranglers — Loren D. Estleman

Between your last prayer and the snap of the rope there's no time for mercy...

The first victim was cut down from a limb outside Fort Benton. The second, bound and strung up in Bear's Paw. Now, Deputy Page Murdock has discovered two more men swinging from a hanging tree among the aspens along the Missouri River. They aren't drifters. They aren't bandits. They're the law. And like every man with a badge, they're wanted -- by a renegade posse who live by their own cold-blooded rules.

The Montana Territory is their new killing ground. And Murdock has just crossed the border.
