Lannigan's Revenge — Mel Marshall

He was Texas Rough-And Texas Ready
He'd begun as a cowpuncher, a loner who traveled the Texas plains from Red River to the Concho. But once he threw in with China Slim, he had a new name...and a new profession. Now he was Lobo Lannigan. And he was what few men had the patience or nerve to be-a wolfer.

Lannigan was hard on the wolves that ravaged longhorn cattle, but he was harder still on anyone rash enough to cross him. Because the fuke shotgun he carried did more than kill a man-it cut him in half with a blast from its twin barrels.
