“Her laughter may have been hysterical,” murmured the Professor, pulling up his robe for greater comfort, and revealing the fact that beneath he wore a pair of very soiled gray flannel trousers rolled up some six inches above his sandals. “No doubt a visit from a High Priest is somewhat awe-inspiring.” At the end of further discussion, a dinner menu for Zalithea was decided upon, and Mahmoud given the necessary orders. A new spirit of restlessness had descended upon the party. If they had solved their first great problem, another faced them. Barry, having prepared for the evening meal, climbed the side of the _wâdi_ to that spot from which on the night of their arrival he had watched the sun setting. It was not so long ago. It seemed an age. He knew that something had happened in the interval which marked the end of one phase of his life, the beginning of another. Now that he had actually seen Zalithea, that vague dread which had sometimes troubled him when he had found himself thinking of the girl on the balcony had gone. Yet, he asked himself to-night, did not his recognition of this girl increase rather than solve the mystery? Since it could not possibly have been Zalithea he had seen on that balcony in New Jersey, then in the garden of Mr. Brown’s house, and later on Fifth Avenue, it must have been her living double!--this or, as others had suspected, a delusion. But why should he have suffered this delusion, not once, but many times, immediately prior to the night that the papyrus came into his father’s possession? Surely he was justified in believing that only some form of telepathy or clairvoyance could explain it… and that this explanation presupposed a mysterious bond of sympathy between himself and the girl he was destined to meet? The Ancient Egyptians, he understood, believed in reincarnation. Since their wisdom was so great in such matters, as the extended life of Zalithea proved, quite possibly they were right. _She_ had slept, miraculously, living on; but _he_ had died, in the ordinary way, and was now reborn--in the ordinary way! He recalled, was ever recalling, how she had looked at him in the moment of opening her long, dark eyes. Death had effaced physical memory in his own case; only subconscious memory remained. But Zalithea, never having died, remembered! They had met before, in those remote days--and she remembered him! It was an idea that first delighted and then terrified Barry. He had imagined, on that night in his father’s library, that the shadow of Ancient Egypt was creeping out to touch him. He had been right! What this inexplicable discovery might mean to John Cumberland, to Danbazzar, to Professor Blackwell, he could only dimly foresee. But what did it mean to him? This he could not foresee at all. And then, as he began mechanically to climb down to the camp, the sound of a distant voice reached his ears. It was a laughing voice… and he knew that he had heard it before!
