Oklahoma wildlife photographer Jim Cutter had nothing more in mind than making a decent image of a hungry coyote. Instead, a different kind of predator, a hired killer, appeared in his viewfinder and a cold-blooded murder was captured in startling color on a digital memory card.The assassin had memories of his own, ones that went back more than one hundred and fifty years, memories which drove him to the edge of madness and a never-ending thirst for revenge.
