Bull-dog Drummond: The Adventures of a Demobilised Officer Who Found Peace Dull

Bulldog Drummond was one of the most popular fictional characters of the 1920s and 1930s. Bulldog Drummond, published in 1920, was the book that launched the career of this gentleman crime-fighter and adventurer. In Bulldog Drummond we meet Captain Hugh Drummond, and he's bored. Peacetime does not agree with him. He misses the excitement of the war. So he places an ad in the newspaper, offering his services in any kind of adventure regardless of its legality or of the danger involved. Most of the replies are unpromising but then he hits pay dirt - a genuine damsel in distress. (Goodreads)
