To assist him, he hires a destitute young physician, who explains his predicament: "As ill luck would have it, however, I had got into the wrong set, and before I had been two years in the hospital was over head and ears in such a quagmire of debt and difficulties that it looked as if nothing but an absolute miracle could serve to extricate me." That miracle seems to have come to him in the person of Dr. Here we find him deep in the wilds of Northumbria conducting an experiment of longevity and restoration of youth with another somewhat naive assistant. In six months' time, if all goes well, I will have a man walking upon this earth who, under certain conditions, shall live a thousand years."
