But to-day in the midst of their discourse Kirstie felt a sudden uneasiness. Explain it she could not. Yet there came to her a sense, almost amounting to certainty, that Mrs. Johnstone was in trouble and had instant need of her. She had left her but a few minutes, and in ordinary health; there was no reason to be given for this apprehension. Nevertheless, as I say, she felt it as urgent as though her mistress's own voice were calling. Mr. Seton observed her change of colour, and broke off his chat to ask what was amiss. She knew that if she stayed to explain he would laugh at her for a silly fancy; and if it were more than a fancy, why then to explain would be a loss of precious time. Pleading, therefore, some forgotten duty, she left the good man hurriedly, and hastening out through the shop ran across Parliament Close and up the great staircase as fast as her legs could take her. By the time she reached the fourth flight of stairs she began to feel ashamed of the impulse which brought her, and to argue with herself against it; but at the same time her ears were open and listening for any unusual sound in the rooms above. There was no such sound until she had mounted half-way up the sixth flight, when she heard a light footstep cross the landing, and, looking up, saw the barber's door very gently closing and shutting out a glimpse of his white jacket. For the moment she thought little of this. The latch had scarcely clicked before she reached the landing outside, from which the last flight ran straight up to her mistress's door. It stood open, though she had closed it less than a quarter of an hour before. This was the first time she had found it open on her return. She caught at the stair-rail. Through the door and over the line of the topmost stair she could just see the upper panes of the window at the back of Mrs. Johnstone's room. A heavy beam crossed the ceiling in front of the window, and from it, from a hook she had used that morning for twisting her yarn, depended a black bundle. The bundle--it was big and shapeless--swayed ever so slightly between her and the yellow light sifted through the window. She tottered up, her knees shaking, and flung herself into the room with a scream. While she fumbled, still screaming, at the bundle hanging from the beam, a step came swiftly up the stair, and the barber stood in the doorway. She recognised him by his white suit, and on the instant saw his face for the first time. He was a negro. He laid a finger on his lips. Somehow the light showed them to her blood-red, although the rest of his features, barring the whites of his eyes, were all but indiscernible in the dusk. And somehow Kirstie felt a silence imposed on her by this gesture. He stepped across the boards swiftly and silently as a cat, found a stool, and set it under the beam. In the act of mounting it he signalled to Kirstie to run downstairs for help.
