The Canyon O’Grady series ran for 14 books between 1989 and 1992, following a frontier agent whose government assignments take him into dangerous situations across the American West. David Robbins uses the spy-meets-Western premise to combine the two genres, with O’Grady tracking counterfeiters, assassins, and conspirators through frontier towns and open wilderness.
Starting with Dead Men’s Trails, the series delivers steady action with the added wrinkle of O’Grady’s dual identity as both a gunfighter and a covert operative. Titles like The Lincoln Assignment and Assassin’s Trail lean into the espionage angle, while others like Comstock Crazy and Rio Grande Ransom emphasize traditional Western confrontations. The series is a solid example of the genre-blending adventure fiction Robbins was producing in large quantities during this period.
