Able Gate — Douglas Hirt

Ruthless badman Barrister McClain has sworn to avenge his brother's death - and that means nailing the hide of Able Gate to the barn wall. But big-name gunfighter and secret Cavalry agent Gate is laying low up Montana way, undercover as the mild-mannered artist Abernathy T. Gatelatch. Even as McClain thunders into town with pistols smoking, the army sends Gate away on a special mission.
