"It is the strangest case I have ever known," murmured old Miss Clifford in perplexity. "What do you suppose is the reason for her turning against the doctor so suddenly? Why, I thought they were on the best of terms? And where do you suppose she has been? Did you notice all this mud down the side of her clothes? And no hat, nor bag—so she must be without money."

He nodded gravely, watching eagerly for the least sign of returning consciousness. He could not tell whether Sartorius had administered a piqûre of some kind to her or not, and the uncertainty filled him with apprehension. He could not rid his mind of Esther's stricken cry, "If he does that again I'm finished!" What was it she meant? Was it possible that those red dots on her arm furnished the answer? She might have been out of her senses when she said that, of course. If what the doctor averred was the case, then it was part of her delusion to believe he was trying to injure her. How could one know the truth? She might die now, so easily; then one could never find out.

She might die——! The fear of this tortured him. The solution of the mystery, even the question of whether his father's death had been due to natural causes or not sank into comparative insignificance beside that terrifying possibility. Nothing could undo what was done, nothing could bring his father back—but here was this girl whom he loved apparently about to slip over the border-line before his eyes and he could do nothing to save her. The thought drove him distracted.

A maid brought the hot-water bottle: they put it near Esther's feet, which were icy to the touch, even through her thin stockings. They loosened her clothing, although there was not much to be done in that line, her slender body being innocent of stays. Presently Miss Clifford raised an anxious face.

"Don't you think we'd better get him to do something after all?" she whispered nervously. "I'm rather frightened!"

He frowned and shook his head, at the same time realising how strange his refusal must strike her. Before he could frame a reasonable reply Chalmers returned to inform him that he had found a doctor, who would be with them in a few minutes.

"Thank God! Dido, we'll wait for him."

"Very well, my dear, if you think it's safe."

She glanced doubtfully at the inert form under the pink coverlet.

"I know what you're thinking," he said softly, putting his hand on her shoulder, "but I believe I am acting for the best. You must simply take my word for it."
