A vivid gleam crossed his face at these words, but whether of incredulity or satisfaction I could not tell.

"But suppose I die in the mean time?" he objected.

That objection was a fair and obvious one. His malady would not pause in its insidious attack while I was seeking Olivia. I deliberated for a few minutes, endeavoring to look at a scheme which presented itself to me from every point of view.

"I do not know that I might not leave you in your present position," I said at last; "it may be I am acting from an over-strained sense of duty. But if you will give me a formal deed protecting her from yourself, I am willing to advance the funds necessary to remove you to purer air, and more open quarters than these. A deed of separation, which both of you must sign, can be drawn up, and receive your signature. There will be no doubt as to getting hers, when we find her. But that may be some months hence, as I said. Still I will run the risk."

"For her sake?" he said, with a sneer.

"For her sake, simply," I answered; "I will employ a lawyer to draw up the deed, and as soon as you sign it I will advance the money you require. My treatment of your disease I shall begin at once; that falls, under my duty as your doctor; but I warn you that fresh air and freedom from agitation are almost, if not positively, essential to its success. The sooner you secure these for yourself, the better your chance."

Some further conversation passed between us, as to the stipulations to be insisted upon, and the division of the yearly income from Olivia's property, for I would not agree to her alienating any portion of it. Foster wished to drive a hard bargain, still with that odd smile on his face; and it was after much discussion that we came to an agreement.

I had the deed drawn up by a lawyer, who warned me that, if Foster sued for a restitution of his rights, they would be enforced. But I hoped that when Olivia was found she would have some evidence in her own favor, which would deter him from carrying the case into court. The deed was signed by Foster, and left in my charge till Olivia's signature could be obtained.

As soon as the deed was secured, I had my patient removed from Bellringer Street to some apartments in Fulham, near to Dr. Senior, whose interest in the case was now almost equal to my own. Here, if I could not visit him every day, Dr. Senior did, while his great professional skill enabled him to detect symptoms which might have escaped my less experienced eye. Never had any sufferer, under the highest and wealthiest ranks, greater care and science expended upon him than Richard Foster.

The progress of his recovery was slow, but it was sure. I felt that it would be so from the first. Day by day I watched the pallid hue of sickness upon his face changing into a more natural tone. I saw his strength coming back by slight but steady degrees. The malady was forced to retreat into its most hidden citadel, where it might lurk as a prisoner, but not dwell as a destroyer, for many years to come, if Foster would yield himself to the régime of life we prescribed. But the malady lingered there, ready to break out again openly, if its dungeon-door were set ajar. I had given life to him, but it was his part to hold it fast.
