Bulldog Drummond's Secret Police is a 1939 American country house murder mystery film directed by James Patrick Hogan, based on the H. C. McNeile novel Temple Tower.
Francis Gerard Luis Fairlie (1 November 1899 – 31 March 1983) was an English author and scriptwriter on whom Sapper (H. C. McNeile) based the character of Bulldog Drummond.
Bulldog Drummond, the hero of the stories by "Sapper", was an officer in the Loamshire Regiment (in this case the 'Royal Loamshires') during the First World War, as was one of the characters in The Life and Death of Colonel Blimp.
