''Yes,' said he, 'any excitement is dangerous for one like me. You see in me a man condemned to death by every member of the faculty that I have ever consulted. I dare say you mean kindly, and by that look of incredulity, you would seek to comfort me.' ''Well, doctors are often mistaken,' I said. ''True; but I am convinced their predictions in my case will be literally fulfilled, for when this terrible disease of the heart once lays its hold upon a man, it never relaxes its deadly grasp. But,' said he, raising himself to a sitting posture, 'but I _will_ not die, I _must_ live. One fixed purpose, one great aim sustains me, and I feel that till I have accomplished this, the thread of life, frail as I know it is, strained as I feel it oft to be, still, still I have a firm presentiment it will hold out.'

His hair, which curled naturally, was, however, growing thin; a few deep lines were furrowed on his brow, and the corners of his mouth wore, as it were, unconsciously, at times, a disdainful air, and as he slept I could trace how the fire of youthful passion had brought his manhood to premature decay. 'Although the veil of mystery had been rent, my curiosity was only whetted, by no means gratified. Who could this man be for whose arrival, according to my hostess' account, he had been waiting with such feverish impatience? What journey could he have returned from, in such shattered health; and finally, what was this great purpose, on the successful issue of which, he seemed to stake his all, on which he declared his life to hang?
