The old woman arranged the tea-things on her tray, but still kept a furtive watch on her master, who sat with his head a little bent, and his bright black eyes fixed on the fire with that intensity of gaze peculiar to eyes which see something far away from the object they seem to contemplate. She was in the habit of watching Mr. Sheldon rather curiously at all times, for she had never quite got over a difficulty in realising the fact that the black-eyed baby with whom she had been so intimate could have developed into this self-contained inflexible young man, whose thoughts were so very far away from her. To-night she watched him more intently than she was accustomed to do, for to-night there was some change in his face which she was trying in a dim way to account for.

He looked up from the fire suddenly, and found her eyes fixed upon him. It may be that he had been disturbed by a semi-consciousness of that curious gaze, for he looked at her angrily,—"What are you staring at, Nancy?"

It was not the first time he had encountered her watchful eyes and asked the same impatient question. But Mrs. Woolper possessed that north-country quickness of intellect which is generally equal to an emergency, and was always ready with some question or suggestion which went to prove that she had just fixed her eyes on her master, inspired by some anxiety about his interests.

"I was just a-thinking, sir," she said, meeting his stern glance unflinchingly with her little sharp gray eyes, "I was just a-thinking—you said not at home to any one, except Mr. George. If it should be a person in a cab wanting their teeth out sudden—and if anything could make toothache more general in this neighbourhood it would be these March winds—if it should be a patient, sir, in a cab—"

The dentist interrupted her with a short bitter laugh.

"Neither March winds nor April showers are likely to bring me patients, Nancy, on foot or in cabs, and you ought to know it. If it's a patient, ask him in, by all means, and give him last Saturday week's Times to read, while I rub the rust off my forceps. There, that will do; take your tray—or, stop; I've some news to tell you." He rose, and stood with his back to the fire and his eyes bent upon the hearthrug, while Mrs. Woolper waited by the table, with the tray packed ready for removal. Her master kept her waiting so for some minutes, and then turned his face half away from her, and contemplated himself absently in the glass while he spoke.

"You remember Mrs. Halliday?" he asked.
