"Now, Miss Bolitho," he said as he went away, "I want you to understand that Paul Stepaside's mother is not the only patient I have. You are another. You must go to bed immediately."

"I could not—I could not!" she cried.

"Very well, then," said the doctor. "I noticed as I came up that there was a fire in Stepaside's study. There's a comfortable sofa there. Go and lie down."

"I could not lie down!"

"But I say you can, and you must!" said the doctor. "Here, I've brought something for you."

He poured a powder into a glass of water, and bade Mary drink it. The girl obeyed him.

"Now," he said. "Come down at once."

He led her downstairs by the arm into Paul's study, and having arranged the cushions on the sofa, he insisted on her lying down. Seizing a rug, he wrapped her up in it just as a father might.

"I'm not going to have you ill," he said. "Remember that! I'll call again to-night, but not before ten o'clock. I've a busy evening before me. In less than half an hour you'll be asleep, and you'll sleep for at least three hours; then you'll wake up better. By that time some dinner will be ready for you. What a grand thing it is to have a meddling fellow who takes everything out of your hands, isn't it?" and he gave the ghost of a laugh.

A few minutes later Mary felt a sense of drowsiness creeping over her, and then became unconscious.
