This fourth reel opens with a scene showing the dispersing of a street crowd which had been attracted by the unusual sight of a limousine car filled with fashionably gowned ladies being stopped on the broad highway while detectives and the police climb aboard in a vain effort to find stolen property. John, the country boy, is seen to leave Margaret’s automobile downhearted and shamefaced at his failure to find the missing D’Rida jewels upon Count D’Orley. Margaret and her aunt return to their home after a pleasant ride through the city streets. The Count arrives at his home in a disheveled condition and vows vengeance on the country. Meanwhile the detectives have shadowed the Count and are watching his house. The next morning, Margaret and her aunt decide to attend the races at Piping Rock and all unconscious of the duplicity and villainy of Count D’Orley, who is using Margaret as a dupe, the two ladies leave the house and start for the races. As they pass out of the front door, the stolen necklace drops from Margaret’s muff out on the pavement, where for twenty-four hours it had been secreted unknown to Margaret. A detective, standing across the street, sees the necklace drop and after Margaret and her aunt drive away, picks it up, vowing vengeance on the Count, whom he is certain had placed the necklace in Margaret’s muff. Margaret and her aunt decide to go shopping before attending the races, and stop at Bonwit Tellr & Co.’s famous store on Fifth Avenue. The scene shows the interior of Bonwit Teller’s store with live models trying on gowns. The next scene shows the races at Piping Rock with scores of the most notable personages in New York’s four hundred. While at the races, the detective calls upon the Count and flashes the necklace in his face, demanding an explanation. Having no real evidence against the Count, the detective is compelled to withdraw. That evening, on Margaret’s return, the detective calls upon her and demands an explanation of how the necklace found its way into her muff. Frightened at the detective’s presence and his accusations, she goes to the telephone and calls up District Attorney Whitman. The last scene shows New York’s fighting District Attorney in his office in the Criminal Court Building answering the telephone and assuring Margaret of his co-operation.
