"That morning a kid reporter from the local newspaper made his way up the stairs to meet me on the retirement home's porch. He wanted my life story, secrets and all, and he wasn't fixing on settling for anything less. After some thought, I asked myself: what could it hurt? All them killers are long gone by now. Ain't no point in keeping it to myself any more…" LAWDOG In the Old West, where a man could be shot for just about anything and the law was that there was no law, Saginaw Bob Magruder hit bottom in the depths of depravity. Known everywhere as the most ruthless of all wanted criminals, Saginaw Bob could kill a child without thinking twice. U.S. Marshal Hayden Tilden was still a growing boy when Magruder curved the path of Tilden's life-and butchered his entire family. Left to fend for himself, young Hayden vowed to exact vengeance on Magruder, if it took his whole lifetime. So began his personal crusade-and the beginning of an extraordinary career. Hailed as the most fearless lawdog of the Old West, at times Tilden blurred the line between U.S. marshal and hired assassin. And in doing so, he etched a name for himself on the pages of American history by saving the West, time and again, from its fiercest enemy-itself.
