The Last Door (1921)

At a reception given at the Rogers mansion in his honor, Somerset Carroll surprises the guests by averring that he would give aid to a female convict reported to have escaped. Later, alone in the library, he is appealed to by a young girl who confesses to being pursued by the police, and he takes her to his own house. There she reveals herself to be Helen Rogers, playing a game with him on the advice of her guests. He then declares himself a crook, holding the real Carroll prisoner, with the intention of robbing the Rogers mansion. She follows and shields "The Magnet" from the police, the real Carroll having escaped and notified them, and through her interference he eludes his would-be captors.
