Larby! El Arby, my son? Did you say El Arby? Of Tangier, too? A Moor? Or was he a Spanish renegade turned Muslim? But no matter—no matter.

"He was my guide," said the American, "and a most brazen hypocrite, always cheating me. I let him do so, it amused me—always lying to my face, and always fumbling his beads—'God forgive me! God forgive me'—an appropriate penance, you know the way of it. 'Peace, Sidi!' said the rascal: 'Farewell! Allah send we meet in Paradise.' But the devil meant that we should meet before that. We have met. It was a hot moment. Do you know the Hamadshá Mosque? It is a place in a side street sacred to the preaching of a fanatical follower of one Sidi Ali bin Hamdoosh, and to certain wild dances executed in a glass and fire eating frenzy. I thought I should like to hear a Moorish D. L. Moody, and one day I went there. As I was going in I met a man coming out. It was Larby. 'Beeba!' he whispered, with a tragic start—that was his own name for me on the journey. 'Keep your tongue between your teeth,' I whispered back. 'I was Beeba yesterday, to-day I'm Sidi Mohammed.' Then I entered, I spread my prayer-mat, chanted my first Sura, listened to a lusty sermon, and came out. There, as I expected, in the blind lane leading from the Hamadshá to the town was Larby waiting for me. 'Beeba,' said he, with a grin, 'you play a double hand of cards.' 'Then,' said I, 'take care I don't trump your trick.' The rascal had thought I might bribe him, and when he knew that I would not I saw murder in his face. He had conceived the idea of betraying me at the next opportunity. At that moment he was as surely aiming at my life as if he had drawn his dagger and stabbed me. It was then that I disgraced my principles."

"How? how?" I said, though truly I had little need to ask.

"We were alone, I tell you, in a blind lane," said the American; "but I remembered stories the man had told me of his children. 'Little Hoolia,' he called his daughter, a pretty, black-eyed mite of six, who always watched for him when he was away."

I was breaking into perspiration. "Do you mean," I said, "that you should have—"

"I mean that I should have killed the scoundrel there and then!" said the American.

"God forbid it!" I cried, and my hair rose from my scalp in horror.

"Why not?" said the American. "It would have been an act of self-defense. The man meant to kill me. He will kill me still if I give him the chance. What is the difference between murder in a moment and murder after five, ten, fifteen, twenty days? Only that one is murder in hot blood and haste and the other is murder in cold blood and by stealth. Is it life that you think so precious? Then why should I value his life more than I value my own?"

I shivered, and could say nothing.

"You think me a monster," said the American, "but remember, since we left England the atmosphere has changed."
