"I have been there only three weeks, and I am seriously concerned about her. It is because she told me you were once her medical attendant that I am here to-day."

"Yes. But as I have ceased attendance upon the lady I hardly know why you should have called."

"I simply had to come. Mrs. Chard has no doctor attending her at present. I understand that she has had none since you left. And it is quite time that somebody was on the spot to--to look after her. Otherwise I believe she will die."

"Why do you think that?"

"Because she is being kept almost continuously under the influence of drugs, administered by her husband and her French maid," said Isla quite clearly and unhesitatingly. "I believe myself there is nothing the matter with her except that, and if she were removed from it all she would get quite well."

Dr. Stephens took a turn across the floor, and when he came back to Isla's side his face was even graver than it had been.

"Miss Mackinnon, I don't for a moment doubt the truth of what you are saying. On the contrary, I know it to be perfectly true. But we are quite powerless."

"Oh, how can you say that! It is terrible if two responsible persons know that this wicked thing is going on and take no steps to stop it! I can't be a party to it, and I was in hopes that you would help me."

"I was kicked out of the house by that unspeakable cad, Chard, and I can't go back again. We have no possible way of getting at him, except one--to lodge a complaint with the police. Are you prepared to do that? Frightful responsibility is incurred by taking that step, of course--to say nothing of the publicity attending it."

Isla sank back.
