Because he turned aside from the trail a moment to look into a pair of dazzling, feminine eyes, Dan Riley, Ranger, allowed wanted men to escape. How he took the trail after four outlaws, to either capture or slay them and vindicate himself, how he met them, one by one, how those same feminine eyes aided him and righted the wrong they had done, is told in The Blocked Trail -- a trail blocked by intrigue, by violence, by gunplay, hard riding and hard fighting, but over which Dan Riley traveled, hurdling all obstacles. Some men called him "Romance Riley" in derision. Then he became known as El Sombrero, because on the leather band of his hat the names of the four were carved, to be burned off one by one as he got them. And then he found real romance when he least expected it, and won his heart's desire after he had accomplished his mission and could look his superior officers in their faces again. The Blocked Trail is a dramatic chunk of life in the raw, swift in action, rich in humorous moments.
