The Seventh Man by Max Brand, tells part of the story of the larger-than-life western character, Dan Barry, known as "Whistling Dan," and his alter-ego companions, Black Bart, the wolf-dog, and Satan, the indomitable black stallion. It's also the story of Kate Cumberland and the incredible five-year-old daughter of Kate and Dan, Joan. We first see Dan as a gentle, caring man with a deep sense of fairness. But then, after six years of a peaceful life in their mountain cabin Dan, more feral than human, sets out to revenge an injustice by killing seven men. Ultimately, it is his devot.
