“‘It is useless,” he said coldly. “‘Then I will find it out,’ I cried. “‘You cannot,’ he answered; ‘it came to me by chance. There is one ingredient which you can never get. Save that which is in the ring of Thoth, none will ever more be made.’ “‘In the ring of Thoth!’ I repeated, ‘where then is the ring of Thoth?’ “‘That also you shall never know,’ he answered. ‘You won her love. Who has won in the end? I leave you to your sordid earth life. My chains are broken. I must go!’ He turned upon his heel and fled from the chamber. In the morning came the news that the Priest of Thoth was dead. “My days after that were spent in study. I must find this subtle poison which was strong enough to undo the elixir. From early dawn to midnight I bent over the test-tube and the furnace. Above all, I collected the papyri and the chemical flasks of the Priest of Thoth. Alas! they taught me little. Here and there some hint or stray expression would raise hope in my bosom, but no good ever came of it. Still, month after month, I struggled on. When my heart grew faint I would make my way to the tomb by the palm-trees. There, standing by the dead casket from which the jewel had been rifled, I would feel her sweet presence, and would whisper to her that I would rejoin her if mortal wit could solve the riddle. “Parmes had said that his discovery was connected with the ring of Thoth. I had some remembrance of the trinket. It was a large and weighty circlet, made, not of gold, but of a rarer and heavier metal brought from the mines of Mount Harbal. Platinum, you call it. The ring had, I remembered, a hollow crystal set in it, in which some few drops of liquid might be stored. Now, the secret of Parmes could not have to do with the metal alone, for there were many rings of that metal in the Temple. Was it not more likely that he had stored his precious poison within the cavity of the crystal? I had scarce come to this conclusion before, in hunting through his papers, I came upon one which told me that it was indeed so, and that there was still some of the liquid unused. “But how to find the ring? It was not upon him when he was stripped for the embalmer. Of that I made sure. Neither was it among his private effects. In vain I searched every room that he had entered, every box and vase and chattel that he had owned. I sifted the very sand of the desert in the place where he had been wont to walk; but, do what I would, I could come upon no traces of the ring of Thoth. Yet it may be that my labours would have overcome all obstacles had it not been for a new and unlooked-for misfortune.
