Excerpt: "The three partners, saddle-chums for years, ever seeking mutual employ, known through Texas and Arizona as the "Three Musketeers of the Range," sat on the porch of the ranch-house, discussing business and lighter matters. One year before they had pooled their savings and Sandy Bourke, youngest of the three and the most aggressive, coolest and swiftest of action, had gloriously bucked the faro tiger and won enough to buy the Three Star Ranch and certain rights of free range." J. Allan Dunn (1872-1941) was one of the high-producing writers of the American pulp fiction. He first made a name for himself in pulp magazine Adventure. He was a specialist in South Sea stories, and pirate tales. His main genres were adventure and western, but he also wrote a number of detective stories.
