The Gunsmith series, written by Robert J. Randisi as "J.R. Roberts," is already in the CU. In the novel Death Times Five, Clint Adams is asked by Judge Parker to apprehend a group of young outlaws. Adams, initially unwilling to get involved, tells Parker, "So send someone to stop them. Send Bass. Or that fellow Murdoch you're so all-fired proud of." Bass is Bass Reeves, a real U.S. Marshal, but "Murdoch" is a reference to Page Murdock, a Marshal featured in books by Loren D. Estleman. Randisi refers to Murdock in two of his other Western novels, the standalone Texas Iron and Bounty on a Baron, which is part of a series featuring a bounty hunter named Decker.
