“Special Officer McCloud, on duty at the quarantined house of James Wilson, artist and clubman, on Ninety-fifth Street, reported this morning a daring attempt at escape, made at 3 A.M. It is in this house that some eight or nine members of the smart set were imprisoned during the course of a dinner party, when the Japanese butler developed smallpox. The party shut in the house includes Miss Katherine McNair, the daughter of Theodore McNair, of the Inter-Ocean system; Mr. and Mrs. Dallas Brown; the Misses Mercer; Maxwell Reed, the well-known clubman and whip; and a Mr. Thomas Harbison, guest of the Dallas Browns and a South American. “Officer McCloud’s story, told to a Chronicle reporter this morning, is as follows: The occupants of the house had been uneasy all day. From the air of subdued bustle, and from a careful inspection of the roof, made by the entire party during the afternoon, his suspicion had been aroused. Nothing unusual, however, occurred during the early part of the night. From eight o’clock to twelve, McCloud was relieved from duty, his place being taken by Michael Shane, of the Eighty-sixth Street Station. “When McCloud came on duty at midnight, Shane reported that about eleven o’clock the searchlight of a steamer on the river, flashing over the house, had shown a man crouching on the parapet, evidently surveying the roof across, which at this point is only twelve feet distant, with a view of making his escape. One seeing Shane below, however, he had beat a retreat, but not before the officer had seen him distinctly. He was dressed in evening clothes and wore a light tan overcoat. “Officer McCloud relieved Shane at midnight, and sent for a plain-clothes man from the station house. This man was stationed on the roof of the Bevington residence next door, with strict injunctions to prevent an escape from the quarantined mansion. Nothing suspicious having occurred, the man on the roof left about 3 A.M., reporting to McCloud below that everything was quiet. At that moment, glancing skyward, one of the officers was astounded to see a long narrow board project itself from the coping of the Wildon house, waver uncertainly for a moment, and then advance stealthily toward the parapet across. When it was within a foot or two of a resting place, McCloud called sharply to the invisible refugee above, at the same time firing his revolver in the ground.
