It was M. Balabas who answered him. "As you returned from your _bath_, Mr. Chundermeyer?" he said. "At what time was that?" "About a quarter-past seven," was the amazing reply. "But, good Heaven!" cried M. Balabas, "I was speaking to you less than ten minutes ago!" "You are mad!" groaned Chundermeyer, rubbing his bruised wrists. "Have I not been locked in the wardrobe all night!" "Ah, merciful saints," cried M. Balabas, dramatically raising his clenched fists to heaven, "I see it all! You understand, Mr. Kernaby. It is _not_ Mr. Chundermeyer with whom we have been conversing, in whose hands you have been placing your valuables, it is that devil incarnate who three years ago impersonated the Emîr al-Hadj, in order to steal the Holy Carpet; who can impersonate anyone; who, it is said, can transform himself at will into an old woman, a camel, or a fig tree; it is the conjuror, the wizard--Omar of Ispahân!" My own ideas were almost equally chaotic; for although, as I now recalled, I had never throughout the evening obtained a thoroughly good view of the features of the Veiled Prophet, I could have sworn to the voice, to the carriage, to the manner of Mr. Chundermeyer. The puzzling absence of Chief Inspector Carlisle now engaged everybody's attention; and, acting upon the precedent afforded by the finding of Mr. Chundermeyer, we paid a visit to the detective's room. Inspector Carlisle, fully dressed, and still wearing a soft felt hat, as though he had but just come in, lay on the floor, unconscious, with the greater part of a cigar, which examination showed to be drugged, close beside him. * * * * * As I entered my room that night and switched on the light, in through the open window from the balcony stepped Abû Tabâh. His frequent and mysterious appearances in my private apartments did not surprise me in the least, and I had even ceased to wonder how he accomplished them; but-- "You are too late, my friend," I said. "Omar of Ispahân has outwitted you." "Omar of Ispahân has outwitted men wiser than I," he replied gravely; "but covetousness is a treacherous master, and I am not without hope that we may yet circumvent the father of thieves." "You are surely jesting," I replied. "In all probability he is now far from Cairo." "I, on the contrary, have reason to believe," replied Abû Tabâh calmly, "that he is neither far from Cairo, far from the hotel, nor far from this very apartment." His manner was strange and I discovered excitement to be growing within me. "Accompany me on the balcony," he said; "but first extinguish the light." A moment later I stood looking down upon the moon-bathed gardens, and Abû Tabâh, beside me, stretched out his hand. "You see the projecting portion of the building yonder?" "Yes," I replied; "the Harêm Suite." "Immediately before the window there is a palm tree." "I have observed it." "And upon the opposite side of the path there is an acacia." "Yes; I see it."
