Bulldog Drummond

Bulldog Drummond was the first Bulldog Drummond novel. It was published in 1920 and written by H. C. McNeile under the pen name Sapper. The following year it was adapted into a play of the same title starring Gerald du Maurier. In 1929, the book was adapted into a film of the same name starring Ronald Coleman.

Herman Cyril McNeile (28 September 1888 – 14 August 1937), commonly known as Cyril McNeile and publishing under the name H. C. McNeile or the pseudonym Sapper, was a British soldier and author. Drawing on his experiences in the trenches during the First World War, he started writing short stories and getting them published in the Daily Mail. As serving officers in the British Army were not permitted to publish under their own names, he was given the pen name "Sapper" by Lord Northcliffe, the owner of the Daily Mail; the nickname was based on that of his corps, the Royal Engineers.
