The man with no past / Pete B. Jenkins.

In the wilds of Arizona a man wakes up to find that not only does he have a nasty head wound, but amnesia as well. Unaware of who he is, or even where he is, all he has to go on is a name in a bible in the saddlebags of a lame horse grazing nearby. The name is Zachariah Thompson, and an inscription inside the bible says it was presented to him by the grateful citizens of Helena in Montana. Believing himself to be this man, he carries on his way, eventually collapsing and being found unconscious by a rancher and his daughter who nurse him back to health. But when the ranch is attacked by an Apache band, the father is killed, leaving Zach and the rancher's daughter to flee for their lives. But Zach begins to question his identity when he is mistaken for a notorious outlaw.
