The residence of the Reverend John Swinton was on Riverside Drive, although the parish of which he was the rector lay miles away, down in the heart of the East Side. It was thus that he compromised between his own burning desire to aid in the cleansing of the city's slums and the social aspirations of his wife. The house stood on a corner, within grounds of its own, at the back of which were the stables and the carriage-house. A driveway and a spacious walk led to the front of the mansion; from the side street, a narrow path reached to the rear entrance. A visitor to-night chose this latter humble manner of approach, for the simple reason that this part of the grounds lay unlighted, and he hoped, therefore, to pass unobserved through the shadows. The warm, red light that streamed from an uncurtained French window on the ground floor only deepened the uncertainty of everything. The man stepped warily, closing the gate behind him with stealthy care, and crept forward on tiptoe to lessen the sound of the crunching gravel beneath his heavy shoes. It was an undignified entry for an officer of the law who carried his authorization in his hand; but courage was not this man's strong point. His fear was lest he should meet tall, stalwart Dick Swinton, who, on a previous occasion of a similar character, had forcibly resented what he deemed an unwarrantable intrusion on the part of a shabby rascal. The uncurtained window now attracted the attention of the sheriff's officer, and he peered in. It was the rector's study. The rector himself was seated with his back toward the window, at his desk, upon which were piled account-books and papers in hopeless confusion. A shaded lamp stood upon the centre of the table, and threw a circle of light which included the clergyman's silver-gray hair, his books, and a figure by the fireside--a handsome woman resplendent in jewels and wearing a low-cut, white evening gown--Mary Swinton, the rector's wife. The room was paneled, and the shadows were deep, relieved by the glint of gilt on the bindings of the books that filled the shelves on the three sides. The fireplace was surmounted by a carved mantel, upon which stood two gilt candelabra and a black statuette. The walls were burdened by scarce a single picture, and the red curtains at the windows were only half-drawn. On looking in, the impression given was one of luxury and of artistic refinement, an ideal room for a winter's night, a place for retirement, peace and repose.
