Bulldog Drummond, published in 1920, introduces Captain Hugh "Bulldog" Drummond, a bored World War I veteran who advertises for exciting work and becomes entangled in a battle against foreign conspirators. McNeile’s novel combines action, humor, and patriotic fervor, establishing Drummond as a prototype for later adventure and spy heroes. With its blend of tough heroics and lighthearted escapism, Bulldog Drummond became immensely popular, leading to a long-running series and numerous adaptations in film and radio.
