Nothing had been disturbed. Everything was as he had last seen it, save that a layer of dust had collected, thanks to the absence of Mrs. Goss, and that due to the difference of the length of the Palosian day. Nine terrestrial days had passed since Croft had lain his body on the couch.

Rising slowly, he ignited the flame of a small alcohol-lamp and quickly brewed himself a cup of strong beef-extract, which he drank. The hot beverage and the food put new physical life into his sluggish veins, as he knew it would. Seating himself in a chair, he gave himself over to a consideration of the thought he had brought with him from Palos—a thought more weird than any of which he had ever dreamed.

Briefly, Croft had conceived of a way to acquire a physical life on Palos. That was his unheard-of plan, the possibility of which had wakened in his consciousness as Jadgor announced the formal betrothal of Naia to Kyphallos at the end of the month. It was that that had sent him back here to his study and his books.

And after a bit he rose and drew a volume from a case and brought it back to the desk. It was a work dealing with obsessions—that theory of the occultist that a stronger spirit might displace the weaker tenant of an earthly shell, and occupy and dominate the body it had possessed.

He read over the written page and sat pondering once more while the night dragged past. Even as he had gone a step farther in astral projection, carrying it into spirit projection as a further step, so now he was considering a step beyond mere obsession, and questioning whether or not it were possible for a spirit, potent beyond the average ego of earth, to enter and revivify the body laid down by another soul.

His thoughts were of Jasor as he sat there wrapped in thought. The young Nodhurian was dying, unless Croft's medical knowledge was all at fault. Yet he was dying not from disease in the physical sense. His body was organically healthy. It was his soul which was sick unto death. And—here was the wonderful question: Could Croft's strong spirit enter Jasor's body as Jasor laid it aside and, operating on the still inherent and reasonably sound cell-energy still contained within it, possess it for its own?

It was an amazing thought—a daring thought—yet not so far beyond the spirit which had dared the emptiness of the unknown in the adventure which had brought Croft to his present position, thereby inspiring the thought itself. Day broke, however, before Croft made up his mind.

He realized fully that he must remain on earth for a day or two to provide his present body against another period of trance. He realized also that in the experiment he meant to make he might lose that earthly body and fail in his other attempt at one and the same time. But he made up his mind none the less.

Should he succeed, he would live as an inhabitant of Palos—would be able to physically stand between Naia—the one woman of his soul—and her fate—and, winning, be able perhaps to claim her for himself. Against the possibility of such a consummation to his great adventure no argument of a personal peril held weight.

Croft sent for Mrs. Goss, telegraphing her shortly after it was light. He spent the day waiting her arrival in feeding his body with concentrated foods. He met her when she came, and for a week life went on in the Croft house as it had gone on before. Then Croft summoned the little woman and bade her sit down in one of the library chairs. He told her he was engaged on a wonderful investigation of the forces of life. He made her understand dimly he was doing something never attempted before, which, if it succeeded, would make him very happy. He explained that he was about to take a long sleep—that it would last for three, and possibly four days. He forbade her to disturb his body during that time, or to touch it for a week. Then, if he was not returned and in his sane mind, she might know that he was dead.
