All was quiet, except for the talking in the room above. He had done but what many thieves--"parlour-jumpers"--do every day; but there was more ahead. He made his way silently to the basement passage, and passed into the kitchen. The room was lighted, and cookery utensils were scattered about, but nobody was there. He waited till he heard a request in Naylor's gruff voice for "another slice" of something, and noiselessly mounted the stairs. He noticed that the dining-room door was ajar, but passed quickly on to the second flight, and rested on the landing above. Mrs. Naylor would probably have to go downstairs once or twice again, but he did not expect anybody in the upper part of the house just yet. There was a small flight of stairs above the landing whereon he stood, leading to the servant's bedroom and the bathroom. He took a glance at the bathroom with its feeble lamp, its steps, and its open ceiling-trap, and returned again to the bedroom landing. There he stood, waiting watchfully. Twice the thin woman emerged from the dining-room, went downstairs and came up again, each time with food and plates. Then she went down once more, and was longer gone. Meantime Naylor and Telfer were talking and joking loudly at the table. When once again Dorrington saw the crown of the thin woman's head rising over the bottom stair, he perceived that she bore a tray set with cups already filled with coffee. These she carried into the dining-room, whence presently came the sound of striking matches. After this the conversation seemed to flag, and Telfer's part in it grew less and less, till it ceased altogether, and the house was silent, except for a sound of heavy breathing. Soon this became almost a snore, and then there was a sudden noisy tumble, as of a drunken man; but still the snoring went on, and the Naylors were talking in whispers. There was a shuffling and heaving sound, and a chair was knocked over. Then at the dining-room door appeared Naylor, walking backward, and carrying the inert form of Telfer by the shoulders, while the thin woman followed, supporting the feet. Dorrington retreated up the small stair-flight, cocking a pocket revolver as he went. Up the stairs they came, Naylor puffing and grunting with the exertion, and Telfer still snoring soundly on, till at last, having mounted the top flight, they came in at the bathroom door, where Dorrington stood to receive them, smiling and bowing pleasantly, with his hat in one hand and his revolver in the other. The woman, from her position, saw him first, and dropped Telfer's legs with a scream. Naylor turned his head and then also dropped his end. The drugged man fell in a heap, snoring still. Naylor, astounded and choking, made as if to rush at the interloper, but Dorrington thrust the revolver into his face, and exclaimed, still smiling courteously, "Mind, mind! It's a dangerous thing, is a revolver, and apt to go off if you run against it!"
