As we walked along the deserted streets, Gordon suddenly cursed savagely.

"This is a veritable labyrinth we are following, leading nowhere! Here, in the very heart of civilization's metropolis, the direst enemy of that civilization commits crimes of the most outrageous nature and goes free! We are children, wandering in the night, struggling with an unseen evil—dealing with an incarnate devil, of whose true identity we know nothing and whose true ambitions we can only guess.

"Never have we managed to arrest one of the Egyptian's direct henchmen, and the few dupes and tools of his we have apprehended have died mysteriously before they could tell us anything. Again I repeat: what strange power has Kathulos that dominates these men of different creeds and races? The men in London with him are, of course, mostly renegades, slaves of dope, but his tentacles stretch all over the East. Some dominance is his: the power that sent the Chinaman, Li Kung, back to kill you, in the face of certain death; that sent Yar Khan the Moslem over the roofs of London to do murder; that holds Zuleika the Circassian in unseen bonds of slavery.

"Of course we know," he continued after a brooding silence, "that the East has secret societies which are behind and above all considerations of creeds. There are cults in Africa and the Orient whose origin dates back to Ophir and the fall of Atlantis. This man must be a power in some or possibly all of these societies. Why, outside the Jews, I know of no Oriental race which is so cordially despised by the other Eastern races, as the Egyptians! Yet here we have a man, an Egyptian by his own word, controlling the lives and destinies of orthodox Moslems, Hindoos, Shintos and devil-worshipers. It's unnatural.

"Have you ever"—he turned to me abruptly—"heard the ocean mentioned in connection with Kathulos?"

"Never."

"There is a widespread superstition in northern Africa, based on a very ancient legend, that the great leader of the colored races would come out of the sea! And I once heard a Berber speak of the Scorpion as 'The Son of the Ocean.'"

"That is a term of respect among that tribe, is it not?"

"Yes; still I wonder sometimes."
