According to Plan of a One-Eyed Mystic

When Brent Stoddard, frontier Marshal, discovered the body of Pierre Villers, murdered Southern planter, he found a locket containing the picture of a beautiful girl. That locket led him to Mississippi and a romance; and the fact that he caught Viller's killer in record time led him into a hornet's nest of trouble of the sort that requires plenty of quick thinking and fast shooting to handle. How he quelled a band of river pirates and found a bride at the end of the trail makes one of the most thrilling stories ever to come from Charles Alden Seltzer's gifted pen.
