"But how under the sun can this discovery benefit us?" repeated Guy, half angrily. "Can you open our prison for us, Canaris?" The Greek threw a cautious glance toward the door and then whispered in a voice that trembled with emotion: "Nothing is impossible; hope for the best. But stay," he added in sudden fear; "I must have money, or all is lost. Alas! you have none, I am sure." For answer Guy hastily rose, and, loosening his clothes, unhooked a small buckskin belt. He tore open the end and dropped a stream of golden sovereigns into his hand. "Here is money!" he cried. "The Arabs overlooked this when they searched me." The Greek's eyes glittered. "Give me twenty," he said. "That will be plenty." He stowed the coins away in his clothes and picked up the lamp. "I must leave you now," he said. "I will return in the morning." He would have added more, but steps were heard in the corridor. The dungeon door clanged behind him, and Guy and Melton were left in darkness, half stupefied by the strange story they had just heard and by the hope of escape which the Greek so confidently held out to them. CHAPTER XII. A DARING MOVE. When daylight came the captives could scarcely believe that the events of the preceding night had not been all a dream. There was the document, however, to prove their reality, and Guy was deeply studying its faded characters when the Greek arrived. His face was radiant with happiness, an expression which quickly gave way to deep sadness as a big Somali entered with a platter of food. The latter had barely closed the door when Canaris held up a warning finger and motioned the Englishmen to draw near. "It is well," he said softly. "I will tell you what I have done. Near the palace lives a Jewish merchant whom I know well. To him I went last night and by the aid of your gold made a good bargain. On the western side of the city, close by the wall, is a deserted guard-house that was once used before the watch-towers were built. Here the Jew promised to take for me the goods I purchased--namely, a supply of dates, figs, and crackers, three revolvers, three rifles with boxes of shells, three sabers, two ancient bronze lamps with flasks of palm oil, a box of English candles, and four long ropes with iron hooks on the end." "He will betray you to the Emir," said Guy in alarm. "Oh, no," returned Canaris, "no danger of that. I know a little secret concerning my Jewish friend that would put his head above the town walls in an hour's time. The things are even now hidden in the deserted house, you may rely on that." "But how are we going to get out of this infernal dungeon?" asked Guy. "And how can we pass through the streets to the edge of the town?" For answer the Greek opened the leather case that he had brought with him and took out three revolvers, three boxes of shells, a coil of rope, and a sharp knife.
