When the film rights to its "Saint" series proved too expensive to renew, RKO Radio came up with a lookalike property in the form of "The Falcon", even engaging George Sanders, the best of the "Saint" impersonators, to play the studio's newest gentleman detective. The Gay Falcon opens as Gay Lawrence (Sanders) -- aka the Falcon -- is hired to guard a priceless diamond. When the owner of the gem is murdered, suspicious immediately falls upon Lawrence's ex-con chauffeur Goldie (Allen Jenkins). Two more killings occur before Lawrence is able to uncover the insurance scam behind it all. Along the way, he romance a pair of toothsome leading ladies, Helen (played by series regular Wendy Barrie) and Elinor (Anne Hunter). Hans Conried contributes a sparkling bit as a snide police sketch artist.
