Desc: A Dangerous Affair: Directed by Charles Miller. With Herbert Rawlinson, Florence Billings, Charles A. Stevenson, Stuart Holmes. Elderly millionaire James Rance, whose only passion is chess, warns his grandson Tommy, who missed the previous evening's game because he played poker with his uncle Gilbert, that should he miss another game, Gilbert will gain the boy's inheritance. During another poker game the next night, Gilbert provokes a fight between Tommy and another player that results in the other player's supposed death. Meanwhile, Terrence Redmond, the guardian of an orphan he found while fighting in France, falls in love with Dawn Moyer. During Elsie Rance's party at the Hotel Plaza, Terrence gallantly offers to assist Elsie whenever she needs him. The next morning, when Tommy's absence is discovered, Elsie calls Terrence, who, after beating Gilbert's Japanese servant in jujitsu, locates Tommy and Dawn at Gilbert's country home. After Gilbert's attempt to poison Terrence is discovered when a cat dies after drinking Terrence's cream, Terrence fights Gilbert's henchmen with broadswords and wins because of his inherited penchant for violence. Tommy returns in time for the chess match, and Elsie becomes engaged to Terrence's friend Bruce, leaving Terrence free to romance Dawn.
