S6, E9: For revenge on Steed, an old enemy leaves him a deadly legacy in his Will: a jeweled oriental dagger worth a million dollars, known as the Falcon, which various dangerous men are anxious to acquire. Steed is cast in the role of Sam Spade, in a spoof of the Humphrey Bogart movie The Maltese Falcon, with dead bodies piling up in his apartment as one man after another tries to kill him to get hold of the item. Ronald Lacey guest stars as Mr. Green, and Stratford Johns as Mr. Street, in a homage to Bogart's co-star, Sydney Greenstreet.
