About the author
Robert Sidney Bowen (1900–77) also wrote under the name James Robert Richard. He had an incident-packed life; he left school when aged only 14 to drive an ambulance for the French Army in World War One. He survived this experience, and enlisted with the British to fly, having lied about his age, as he surely must have done to get into the French Army. After the war, he worked for the Daily Mail in London, and went on to become editor of Aviation magazine.
He started writing fiction for various pulp magazines, and with the outbreak of World War II, was commissioned to write an aviation series. The Dave Dawson series was the result, followed by another war series, Red Randall. He had a phenomenal work rate, being capable of completing a novel in ten days. After the war, he continued writing, producing boys’ stories featuring sport and adventure. He used the pseudonym James Robert Richard for horse stories (and some on American football).
