"These English have eyes everywhere. They see in the dark like a cat. Yet perhaps with luck and, what is better, German watchfulness, all will be well. Hand me the telephone."

The Turk obeyed silently, but in a manner that suggested resentment at the German's peremptory tone. Wonckhaus spoke into the instrument in German.

"Keep a sharp look-out. Torpedo boats are reported off the coast."

The lieutenant got up and moved towards the door.

"I shall turn in," called Wonckhaus after him. "You had better do the same. We shall be up all night; probably to no purpose. I am tired of this. It would suit one of Von Tirpitz's men better than me."

He lay back in his chair, pulled at his cigar, and finding that it had gone out, threw it away, rose, stretched himself, yawned, and walked slowly into the bungalow.

Frank had heard and seen enough. He knew what the "holy men" were engaged in. It only remained to return on his tracks and report his discoveries to the lieutenant-commander, who would know how to act on them. Slipping back into the wood, he made his leisurely way to his former observation post, where he sat down and ate some food he had brought from the khan, in the slow abstracted manner of one deep in thought. Then he returned by the way he had come, found his horse in the thicket, and rode southward, without hurry, for his friends would not expect him until dark.

On approaching the road, he dismounted, again tied up his horse to a tree, and threw himself on his back. He was very tired, but dared not indulge his longing for a nap, and when he found slumber stealing upon him, he sprang up and strolled about in the woods. The afternoon seemed particularly long. But he was prudent enough not to take to the open road until the fall of night. Then he rode rapidly, passed the khan, turned his horse loose some distance from it, and struck off towards the shore. It was a matter of some ten minutes' walking before he came to the matting, which now lay dry on the beach where it had been left. There he sat, looking over the sea, and listening intently. About an hour later his ears caught the faint sound of muffled oars. He walked down to the brink of the water, waited a few moments until assured that he was not mistaken, then gave a low whistle. The boat pulled in, and Frank, too impatient to await its beaching, waded out towards it and scrambled over the side.

"Well?" whispered the lieutenant-commander.

"O.K. Now it's up to you. I'll tell you all about it when we get clear of the shore."
