Nobody really knows Whistling Dan Barry, not even old Joe Cumberland, who found him as a boy wandering alone in the desert, and raised him as a son. Slight of build, mild of manner and voice, the only man who can ride his wild stallion or tame his wild wolf-dog, Dan is known to be deadly with a six-gun or his hands. And it's definitely a bad idea to make him angry, no matter how many of you there are.
