As he spoke the door opened and Mr. Savage appeared through it, walking much faster than was his wont. I noted also that he gripped the pockets of his swallow-tail coat firmly in his hand.

“Mr. Hare-root and Mr. Mare-root,” he announced.

“Hare-root and Mare-root!” repeated Lord Ragnall.

“Harût and Marût, I expect,” I said. “I think I have read somewhere that they were great magicians, whose names these conjurers have taken.” (Since then I have discovered that they are mentioned in the Koran as masters of the Black Art.)

A moment later two men followed him through the doorway. The first was a tall, Eastern-looking person with a grave countenance, a long, white beard, a hooked nose, and flashing, hawk-like eyes. The second was shorter and rather stout, also much younger. He had a genial, smiling face, small, beady-black eyes, and was clean-shaven. They were very light in colour; indeed I have seen Italians who are much darker; and there was about their whole aspect a certain air of power.

Instantly I remembered the story that Miss Holmes had told me at dinner and looked at her covertly, to see that she had turned quite pale and was trembling a little. I do not think that anyone else noticed this, however, as all were staring at the strangers. Moreover she recovered herself in a moment, and, catching my eye, laid her finger on her lips in token of silence.

One of them shut the door, leaving Savage on this side of it as though they meant him to be present. Then they walked towards us, each of them carrying an ornamental basket made apparently of split reeds, that contained doubtless their conjuring outfit and probably the snake which Savage had found in his pocket. To my surprise they came straight to me, and, having set down the baskets, lifted their hands above their heads, as a person about to dive might do, and bowed till the points of their fingers touched the floor. Next they spoke, not in Arabic as I had expected that they would, but in Bantu, which of course I understood perfectly well.

“I, Harût, head priest and doctor of the White Kendah People, greet you, O Macumazana,” said the elder man.

“I, Marût, a priest and doctor of the People of the White Kendah, greet you, O Watcher-by-night, whom we have travelled far to find,” said the younger man. Then together,
