He waited, motionless, until assured that she had passed down the hall as far as the door of the dining-room. The sound of shuffling chairs evidenced the breaking up of the party, in preparation to return to the ballroom. If Miss McDonald's absence were to escape observation, she would have to slip out now and rejoin the others as they left the house. He again turned down the light, and held back the curtain. "The way is clear now, Miss Molly." There was no response, no movement. He stepped outside, thinking the girl must have failed to hear him. The porch was empty. He stepped from one end to the other, making sure she was not crouching in the darkness, scarcely able to grasp the fact of her actual disappearance. This, then, was why Mrs. Dupont had failed to see any one when she glanced out. But where could the girl have gone? How gotten away? He had heard no sound behind him; not even the rustle of a skirt to betray movement. It was not far to the ground, five or six feet, perhaps; it would be perfectly safe for one to lower the body over the rail and drop. The matted prairie grass under foot would render the act noiseless. No doubt that was exactly the way the escape had been accomplished. Alarmed by the presence of those others, suspecting that the woman within would insist on learning whom Hamlin was attempting to conceal, possibly overhearing enough of their conversation to become frightened at the final outcome, Miss McDonald, in sudden desperation, had surmounted the rail, and dropped to the ground. The rest would be easy--to hasten around the side of the house, and slip in through the front door. Assured that this must be the full explanation, the Sergeant's cheerfulness returned. The company of officers and guests had already filed out through the hall; he could hear voices laughing and talking in the street, and the band tuning up their instruments across in the dance hall. He would go over and make certain of her presence, then his mind would be at ease. He passed out through the deserted hallway, and glanced in at the dining-room, where a number of men were gathering up the dishes. Beyond this the barroom was crowded, a riffraff lined up before the sloppy bar, among these a number in uniform--unattached officers who had loitered behind to quench their thirst. Hamlin drank little, but lingered a moment just inside the doorway, to observe who was present. Unconsciously he was searching for Dupont, half inclined to pick a quarrel deliberately with the fellow or with Connors, determined if he found the little rat alone to frighten whatever knowledge he possessed out of him. But neither worthy appeared. Having assured himself of their absence, Hamlin turned to depart, but found himself facing a little man with long hair, roughly dressed, who occupied the doorway. The hooked nose, and bright eyes, peering forth from a mass of untrimmed gray whiskers, were familiar.
