“But my loss is irreparable. That box contained”—I hesitated. Then I added, “It contained great treasure.”

“May Allah consign the thief to Hâwiyat for ever!” exclaimed one of the men calmly.

“May the Prophet send thee consolation!” added another. “Against Fate thou canst not arm thyself,” observed a third. “May the entrails of the thief be burned!”

To such remarks I returned thanks, and, heedless of the questions they asked concerning the value of the contents of the stolen box, I stood deep in thought. Though the circumstances were somewhat suspicious that my attention should have been diverted in the manner it had, still there was no mistake that the portrait was actually that of my murdered friend; and, further, the thief had not, as far as I had noticed, spoken to any of those around him. Expert pilferers as the Arabs mostly are, I could not in this instance bring myself to believe that I had been the victim of a plot. Again, it was not a pleasant reflection that the thief might have stolen it thinking it contained valuables, and then, finding the hideous object inside, would in such a case most likely give information which would lead to my arrest for murder! My guilt would be assumed, and to prove my innocence I should experience considerable difficulty.

On the other hand, however, the circumstances pointed strongly to the theory that the ragged ruffian had dogged my footsteps in order to obtain possession of the casket. But for what reason? The box had been wrapped in brown paper, there being nothing whatever in its exterior to excite undue curiosity. Was it possible that the thief might have been aware of its contents? Was the possession of this startling evidence of a gruesome tragedy of imperative necessity? If so, why?

None of these questions could I answer. I felt that the robbery was not an ordinary one. It was an enigma that I could not solve. The hand, with its rings, had been stolen from me by one who was evidently an expert thief, and, recognising that any attempt to recover it was useless, I thanked the Arabs in the kahoua for their condolences, and left, turning my steps slowly towards the European quarter.

I recollected that I had promised Zoraida to set out that night on my journey into the distant Desert. Again and again her earnest words in her own musical tongue rang in my ears: “Thou wilt go for my sake,” she had said. “Remember the instructions I have given thee; and, above all, promise to seek no explanation of what thou mayest hear or see regarding me until thou hast returned from Agadez. Thou wilt undertake this mission in order to save my life, to rescue me from a horrible fate that threateneth to overwhelm me!”

Had she already succumbed to the fate she dreaded?

Utterly powerless to obtain any information that might lead to the elucidation of the extraordinary mystery, I at length, after calmly reviewing the situation over a cigarette under the palms in the Place Bresson, resolved to keep my promise to her, and before midnight I left the City of the Corsairs on the first stage of my long, tedious journey southward towards the sun.

The temptation to return to England and leave the mystery unsolved had indeed been great, yet I could not forget that I had pledged my word to a woman I loved better than life. She had declared that I alone could save her, and trusted me. These thoughts caused my decision to attempt the perilous journey. Is it not, indeed, true that sometimes beauty draws us with a single hair towards our doom?
