AN OVERWHELMING majority of Oppenheim’s pulp output were aviation stories, many featuring our intrepid trio, The Three Mosquitoes. In 1933, when the Mosquitoes were winding down their adventures in Popular Publications aviation magazines, Oppenheim tried his hand at a new genre that was very popular at the time—detective fiction. Over the next fourteen years oppenheim would produce eighteen detective stories for the some of the leading magazines in the field—Dime Detective and Dime Mystery Magazines, Popular Detective, Thrilling Detective, Thrilling Mystery, Black Book Detective, Detective Fiction Weekly, Strange Detective Mysteries and Phantom Detective—as well as even ghost writing a Phantom Detective story (”Murder Calls the Phantom” March 1941).

Oppenheim had five stories in the pages of Thrilling Detective—the first two in 1936 and 1937 featured Dave Rogers. Dave Rogers was a motorcycle riding state trooper. In this second of the two published tales, a former state trooper, young Bob Hall, has returned to the station as a Federal Agent investigating a counterfeiting ring that is believed to be operating in the area. Rogers says he’s seen one of the three counterfeiters in the area, but is asked to give Hall a wide berth in his investigation. However, when young Bob Hall turns up frozen solid just a short time after Rogers has seen him speeding by on the other side of town, he throws himself into the case!

From the February 1937 issue of Thrilling Detective, it’s Dave Rogers, State Trooper in Ralph Oppenheim’s “Cold Steel!”
