Quick as a flash he ran the strings from the edge of the gag out through the corners of the open mouth, and bound them tightly behind the German's neck. He needed no further instruction from his chum, seeing that the two had discussed the matter so very often, had discussed it, let us remember, not in connection with the tricing up of a visitor—a visitor so unexpected as von Hildemaller—but in connection with their Turkish jailer.

"Somehow I'd have been sorry for him," Philip murmured, as he seized the blanket-ropes already prepared, and tied von Hildemaller's wrists behind his back.

"What, this beggar?"

"No, no! I was thinking of the jailer. I'd have been somehow sorry for him, for he's been such a decent fellow, such a friendly beggar," corrected Philip. "But this chap! Jingo, ain't it jolly!"

He set about the completion of the job in a manner which showed his delight almost better than words could do, and in a trice had von Hildemaller's wrists most scientifically tied together, and his elbows pulled so close that movement of his upper limbs was out of the question. Then, at a nod from Geoff, these two powerful young fellows gripped the heavy German and lifted him, as if he were a babe, to the wooden divan. It took, perhaps, another two minutes to secure his legs and ankles, and to leave him like a helpless bundle.

"And now?" asked Philip, mopping his forehead, for the work had been furious while it lasted.

"We move!" declared Geoff promptly. "It's getting dusk already, and it's quite dark in this cell. Though, 'pon my word, von Hildemaller's eyes pierce the dusk like gimlets. My word! If only he were free and could do his worst for us! Now let's put the money we promised the Turk on this table, and then go. No time like the present."

They were indeed in the position of being unable to choose the time for the attempt to regain their liberty. In any case they were bound to seize the first opportunity that came, to seize it whenever it came, regardless of the hour or of the circumstances. But the coming of von Hildemaller had forced their hand in a manner neither had anticipated. He had, as it were, complicated their difficulties; for, now that he was secured, trussed like a bird, and laid out helpless, there was still the Turkish jailer to be considered—the man they had proposed to capture, the man who, once shut up in the cell, gagged and triced just as was von Hildemaller, would be out of the way, unlikely to run up against them in the corridor outside, unable to give the alarm and let others know that they were escaping.

"Can't be helped, the change in our plans," said Geoff, as he took another look at the German; "just squint outside, Phil, and tell me whether there's anyone in the corridor. If not, we'll pull off our boots and make our way along it in stockinged feet. Of course, if the jailer turns up, well, we'll have to be guided by circumstances."

In any case there was no time for discussion, no opportunity for making further or other plans, nothing to do but seize the opportunity, strike while the iron was hot, and free themselves from this prison. To strip off their boots and tuck them into their belts was the work of a moment, and then, unarmed but strong as lions—thanks to their own forethought and energy—they tiptoed into the corridor outside and stole rapidly along it, having gently pulled the iron door of their cell to upon the German. Some twenty paces along they found themselves at the head of a short flight of stone steps, and were quickly at the bottom. A turn to the left took them along another corridor, and then both suddenly halted.
