"I shall only be too glad of your company," he answered. "Besides, you have a right to be present, since it is through you I am permitted an opportunity of replacing my venerable ancestor in his tomb. Perhaps you will be good enough to hold yourself in readiness to start at eleven o'clock. Owing to the publicity now given to anything that happens in the ruins of this ancient city, the mere fact that we are returning a mummy to its tomb, of the existence of which the world has no knowledge, would be sufficient to attract a concourse of people whose presence would be in the highest degree objectionable to me."

"You must excuse my interrupting you," I said, thinking I had caught him tripping, "but you have just said that you are going to open a tomb of the existence of which the world has no knowledge. Surely my father opened it many years ago, otherwise how did he become possessed of the mummy?"

"Your father discovered it, it is true, but he stumbled upon it quite by chance, and it was reburied within a few hours of his extracting the mummy. If he were alive now I would defy him to find the place again."

"And you are going to open it to-night?"

"That is my intention. And when I have done so it will once more be carefully hidden, and may woe light upon the head of the man who shall again disturb it!"

I do not know whether this speech was intended to have any special significance, but as he said it he looked hard at me, and never since I have known him had I seen a more diabolical expression upon his countenance. I could scarcely have believed that the human face was capable of such malignity. He recovered himself as quickly, however, and then once more bidding me prepare for the excursion of the evening, took himself off to his cabin and left me to ponder over all he had said.

Eleven o'clock had only just struck that night when the tall Arab, my acquaintance of the Pyramids, came along the deck in search of me. I was sitting with the Fräulein Valerie at the time, but as soon as he told me that Pharos was waiting and that it was time for us to start, I made haste to rise. On hearing our errand my companion became uneasy.

"I do not like it," she said. "Why could he not do it in the daytime? This going off under cover of the night savours too much of the conspirator, and I beg you to be careful of what you do. Have you a revolver?"

I answered in the affirmative, whereupon she earnestly advised me to carry it with me, a course which I resolved to adopt. Then bidding her good-bye I left her and went to my cabin, little dreaming that upward of a week would elapse before I should see her again.

When I joined Pharos on deck I discovered that he had made no difference in his attire, but was dressed just as I had always seen him, even to the extent of his heavy coat which he wore despite the heat of the night.
