The President's Mystery (1936).

Betty Furness, ca. 1936

FDR, an honorary member of the Baker Street Irregulars, proposed an idea for a mystery novel in a conversation with editor Fulton Oursler: "How can a man disappear with $5 million of his own money in negotiable form and not be traced?" As B. V. Lawson discusses, authors teamed up to write the tale for Liberty magazine: S. S. Van Dine, John Erskine, Rupert Hughes, Samuel Hopkins Adams, Rita Weiman, and Anthony Abbot (the mystery alter ego of Oursler). It was subsequently turned into a book and this 1936 film, with proceeds going to the Georgia Warm Springs Foundation. Henry Wilcoxen and Betty Furness costar.
