"You are Esbul, eh?" he asked.

"And you, Excellency, you are Keith Pasha."

"The message; give it to me," demanded Geoff fiercely, worked up by the occasion. "Yes, I am Keith Pasha, and your message comes from Douglas Pasha, my dear guardian."

It was with a shout of joy that he recognized the handwriting of that gallant soldier who had been as a father to him, and tearing the missive open he read it with an eagerness which was plainly apparent to the man who had brought it.

"If this reaches the hand of my ward, Geoff Keith, or of any British officer, let him give information of my position to the Commanding Officer of any expedition which may come from India to Mesopotamia. I have little time or space or means whereby to write a long message, and therefore must compress my information. I am a prisoner lying in a cell within a Turkish fort to the north and west of Bagdad, but where precisely I cannot say, nor do I know the name of this fortress. I was captured by a German named von Hildemaller. His agents trapped me at a place I sought outside Bagdad, and seized me. But for a friendly Turk they would have murdered me on the spot, and, as it is, they handed me over a prisoner. I make no complaint, but if the expedition advances towards Bagdad, let it make an effort to relieve me."

Geoff gasped, and re-read the message—devoured it in fact—for it was good to hear that Joe Douglas was alive, even though he were a prisoner.

"Tell me, Esbul," he said at last, while they continued to ride on slowly side by side, "this message—you received it from Douglas Pasha himself? You know where he is imprisoned?"

"Not so, Excellency, not so, Keith Pasha! This man—this devil, I call him—this German, the smiling, sweet-faced von Hildemaller. Ah! how I know the man, how I hate, detest, and fear him—he is too strong, too cunning, too artful to allow your servant or any other friend of Douglas Pasha to know of his whereabouts. Only von Hildemaller and Turks in high places can tell of the prison in which my master is shut up."

"But then," said Geoff quickly, "how—how came you to get the message?"

"It is shortly told, Excellency. There is a Jew, an Armenian Jew, in the city of Bagdad, a great admirer of my master, an old and trusted friend of his, who has been ever loyal to him."
