The financier's niece and ward was riding in the park one day when her horse ran away. Casey, the cop, rescued her. Then they found that they knew each other when they were children. The girl visited her grandmother in the country, and "the cop" was "the little boy next door." They drifted apart, but the incident in the park brought them together again, and Casey became a frequent visitor at the banker's home. Some time later the banker became involved in speculations. To carry on his market operations he had utilized the funds entrusted to his care. An unexpected visit of the bank examiners precipitated matters, but the banker, aided by his cashier, so arranged matters that the blame fell upon the policeman's brother. The niece overheard arrangements being made for the teller's arrest, and hurried around to his home to give him warning. Before he could escape the police arrive.
