"Does he know?" whispered Mrs. Jakes, feverishly, thrusting close to her. "Does he know—about this?" Her downward-pointing finger indicated the slumbers of Dr. Jakes. "Say, can't you—does he know?"

"He 'd seen him," said Margaret. "I expect he loosened the collar—you know. He wanted to help but I wouldn't let him."

"Is he a friend of yours?" asked Mrs. Jakes again, still in the same agitated whisper.

"Yes," answered Margaret. "He is. It 's all right, really, if only you 'll be sensible and not make a fuss. He 'll help us and then he 'll go away and he 'll say nothing. You did n't think I 'd do anything to hurt you, did you? Are n't we friends?"

Mrs. Jakes stood silent; she asked no questions as to how a London doctor, a friend of Margaret's, chanced to be walking upon the Karoo at night.

"Well," she said at last, with a long sigh; "perhaps we might have needed some help, in any case."

That was all she said, till the footsteps came again across the stoep and down the steps, more deliberately this time, as though something were being carried with precaution. Then they were noiseless for a minute or more on the grass, and at last the figure of Kamis came into the further edge of the lighted circle.

"I had to do it," he said, before either of them could speak, and showed the graduated glass in his hand. "I saw you with your handkerchief."

Margaret, with an instinct of apprehension, looked at Mrs. Jakes. At the first dim view of him, she had roused herself from her dejection, and put on her prim, social face to meet the London doctor effectively. Her little meaningless smile was bent for him; she would make a blameless and uneventful drawing-room of the August night and guard it against unseemly dramatics.

He turned from Margaret towards her and came further into the lamp-light, and she had a clear view of the black face and sorrowful, foolish negro features. She uttered a gasp that was like a low cry and stood aghast, staring.
