She did not know that the audacious fellow who kissed her at the masked fete was her brother's chum. On a surprise visit to the town house she encountered a masked intruder, whom she threatened with a pistol after phoning for the police. Returning from the club, he had recognized her, and in a spirit of fun, he had put on the mask which he found in her traveling bag. Explanations were cut short by the entrance of a real burglar, whom the young man captured and turned over to the police. Then he kissed her again, and this time she was not angry.
