Synopsis by Hal Erickson
Despite what you might think by glancing at the title, The Argyle Case has nothing to do with socks. The film's plot is set in motion when the head of the house of Argyle is murdered. In one of his few talking-picture appearances, silent star Thomas Meighan is the detective on the case. Meighan discovers that the culprit is a member of an espionage ring, intent upon stealing valuable state secrets. Based on a play by Harriet Ford, Harvey J. O'Higgins, and William J. Burns, The Argyle Case was previously filmed in 1917.
