The words were shot at the other horseman, and received an instant answer.

"Master, all is well. We passed through the gate without creating suspicion. There is none who knows of our coming."

"Then drive on," commanded the German to the man seated on the box of the vehicle; "drive on at once."

"But where, where, Master?"

"Where? Ah, I had forgotten that you were ignorant of the place to which I am going. Straight on till I give you an order to turn; the place is some ten miles distant."

Never in all the course of their lives would Geoffrey, Keith, and Philip forget that journey—that journey, that slow, tedious journey over the rough road leading from the western gate of Bagdad, a journey occupying perhaps two hours and a half, a period which appeared to their eager, anxious minds like an eternity. They were tingling with excitement, with expectation, and with impatience. In spite of the many adventures through which they had passed, of the many tight places in which they had found themselves, this undoubtedly was the most trying of all their experiences; for at any moment the German might discover the ruse, might find out that the three who surrounded him were not his hirelings, and might defeat the efforts made to outwit him. Even his heavy breathing, his lolling head, and the fact that he was dozing, hardly helped to minimize the tension of the situation.

"Ah, a building ahead of us, I think!" Geoff whispered to himself, when, having traversed the main road for some eight miles, and turned to the left at von Hildemaller's bidding, they had made their way over a side-track which was indescribably rough and trying; "a building ahead of us. Looks like a big fortress; perhaps it's a prison."

He gave vent to a loud cough, so as to awaken the German, and then once more fixed his eyes on the dull shape he had seen in the distance. As for von Hildemaller, he awoke with a start, and, standing up with difficulty, and setting the rickety chaise swinging, he too peered ahead, and then, making out that distant shape, uttered a hoarse chuckle.

"The place! We are there, or almost so. Good!" Geoff heard him mutter. "Pull up at the main gate," von Hildemaller commanded Esbul. "Now, that will do! You will wait here till I come out again, and you will know what to do, for we have already discussed the matter. Wait, though, I will repeat my instructions: there will be a man with me, a man who will be tied hand and foot, a mere log, of no danger to any one of us. I shall join him in the chaise, and you will drive off immediately. A mile down the road which we have just covered you will halt, for that will be sufficiently far, and voices, even screams, will not be heard over such a distance. You will halt, and then—and then——"

Esbul swung his head round and bent towards the German.
