The Argyle Case was based on a play by Harvey J. O'Higgins and Harriet Ford, which in turn was inspired by the official files of the William J. Burns Agency, an international private detective organization. The head of the house of Argyle is murdered by espionage agents who wish to undermine the well-being of the United States (the film was made the same year that America entered the first World War). Robert Warwick (who also produced) plays the scientific detective who brings the miscreants to heel. The Argyle Case was directed by Ralph Ince, brother of silent-movie mogul Thomas Ince. The film would be remade as a talkie in 1929, with Thomas Meighan in the lead.
