The Circus Queen Murder

New York Police Commissioner Thatcher Colt (Adolphe Menjou) decides to take a vacation after six years of fighting crime, accompanied by his attractive secretary, Miss Kelly (Ruthelma Stevens). On the train to their destination, they spot a rundown circus, "The Greater John T Rainey Shows", heading to the same place. The circus is home to a love triangle: Josie La Tour (Greta Nissen), her husband Flandrin (Dwight Frye) (whom she is intent on divorcing), and her lover The Great Sebastian (Donald Cook (actor)), all three trapeze performers.
