This was the last of eight films in Columbia's "The Whistler" series. While contemporary reviews and Columbia publicity materials list the names of the characters played by Lenore Aubert and Richard Lane as "Alice Barclay" and "Gaylord Travers," respectively, their last names appear in the film spelled "Barkley" and "Traynor." This was the only film in the "Whistler" series that did not star Richard Dix. For additional information on the series, please consult the Series Index and for The Whistler.
