43. The Warrior's Path Louis L' Amour 1980
Although the Sackett series is supposed to be read in a certain order, this one skips back to the first generation born on American soil. 1620 or so, brothers named Yancey and Kin. They spend most of the book breaking up a white female slavery ring, and Kin falls in love with one of the rescued slaves, reputed to be a witch.
Now who among us gentlemen ever thought of a woman as a witch?
