He was becoming more and more convinced that he had to do with a madman.
"Time presses, and I must go," continued the other. "The moment is at hand for which I have waited this weary time. But I must show you out first. Come with me."
Taking up the lamp, he turned from the disordered chamber, and led the student swiftly through the long series of the Egyptian, Assyrian, and Persian apartments. At the end of the latter he pushed open a small door let into the wall and descended a winding stone stair. The Englishman felt the cold fresh air of the night upon his brow. There was a door opposite him which appeared to communicate with the street. To the right of this another door stood ajar, throwing a spurt of yellow light across the passage. "Come in here!" said the attendant shortly.
Vansittart Smith hesitated. He had hoped that he had come to the end of his adventure. Yet his curiosity was strong within him. He could not leave the matter unsolved, so he followed his strange companion into the lighted chamber.
It was a small room, such as is devoted to a concierge. A wood fire sparkled in the grate. At one side stood a truckle bed, and at the other a coarse wooden chair, with a round table in the centre, which bore the remains of a meal. As the visitor's eye glanced round he could not but remark with an ever-recurring thrill that all the small details of the room were of the most quaint design and antique workmanship. The candlesticks, the vases upon the chimney-piece, the fire-irons, the ornaments upon the walls, were all such as he had been wont to associate with the remote past. The gnarled heavy-eyed man sat himself down upon the edge of the bed, and motioned his guest into the chair.
"There may be design in this," he said, still speaking excellent English. "It may be decreed that I should leave some account behind as a warning to all rash mortals who would set their wits up against workings of Nature. I leave it with you. Make such use as you will of it. I speak to you now with my feet upon the threshold of the other world.
"I am, as you surmised, an Egyptian--not one of the down-trodden race of slaves who now inhabit the Delta of the Nile, but a survivor of that fiercer and harder people who tamed the Hebrew, drove the Ethiopian back into the southern deserts, and built those mighty works which have been the envy and the wonder of all after generations. It was in the reign of Tuthmosis, sixteen hundred years before the birth of Christ, that I first saw the light. You shrink away from me. Wait, and you will see that I am more to be pitied than to be feared.
"My name was Sosra. My father had been the chief priest of Osiris in the great temple of Abaris, which stood in those days upon the Bubastic branch of the Nile. I was brought up in the temple and was trained in all those mystic arts which are spoken of in your own Bible. I was an apt pupil. Before I was sixteen I had learned all which the wisest priest could teach me. From that time on I studied Nature's secrets for myself, and shared my knowledge with no man.
"Of all the questions which attracted me there were none over which I laboured so long as over those which concern themselves with the nature of life. I probed deeply into the vital principle. The aim of medicine had been to drive away disease when it appeared. It seemed to me that a method might be devised which should so fortify the body as to prevent weakness or death from ever taking hold of it. It is useless that I should recount my researches. You would scarce comprehend them if I did. They were carried out partly upon animals, partly upon slaves, and partly on myself. Suffice it that their result was to furnish me with a substance which, when injected into the blood, would endow the body with strength to resist the effects of time, of violence, or of disease. It would not indeed confer immortality, but its potency would endure for many thousands of years. I used it upon a cat, and afterwards drugged the creature with the most deadly poisons.
