Trouble's Messenger — Max Brand

Peter Messenger was made for trouble. He was specially trained in the art of death, even though he'd never killed anyone. But his skills with his hands, a gun, or a knife were undeniable. And there was only one person he planned to use them on: Summer Day, the wily medicine man who had tortured and killed a defenseless white. But to get to the one he seeks, Peter will have to take on the whole Blackfoot nation...and hope his extraordinary talents are enough to stay alive against the wrath of an entire tribe.
