Beautiful Daggett Valley was pitted with waiting danger. It was here that Buck Logan plotted to con a half-witted old man into revealing where he had hidden a cache of jewels worth thousands. But schemes don't always go according to plan, and this one was no exception. Before the end of the day, blood would be shed for the sake of greed. And only one man would live to tell the truth behind the Valley of Jewels.
