Within the caves all was quiet. If Tassh lay concealed in the innermost one he gave no sign of his presence. Apparently he had learnt a certain amount of caution, for all tracks between the mouth of the cave and the narrow "needle's-eye" communicating with the two divisions were carefully obliterated. Without a word being spoken the Scouts took up their allotted positions: Simpson and the 1st and 2nd class Scouts of his patrol stationed themselves on either side of the entrance to the inner cave; Atherton and the available "Otters" hid in a deep recess just inside the outer entrance; while Mr Buckley remained without in order to keep the yacht under observation. Slowly, in utter silence, the hours passed. Although the Scoutmaster could not see the time by his watch, he felt fairly convinced that it could not be much past midnight. To the waiting Scouts the period of waiting seemed interminable. At length the Scouts pricked up their ears. From the depths of the inner cave came an uncanny sound. As Simpson afterwards described it, it was like the armoured body of an enormous crab grating over the rocks. This was followed by the deep breathing of a man who had been put to great physical strain. Then came the stealthy footfalls of some one walking over the dry sand that formed the floor of the cave. Simpson and the "Wolves" were tingling with excitement. It was Tassh. The rascally butler began to crawl through the "needle's eye." Once or twice he paused, as if scenting danger; then, drawing himself clear, he regained his feet. It was as much as the "Wolves" could do to restrain themselves from falling upon and overpowering their quarry, since the man stood almost within arm's length of Simpson on the one hand and Neale on the other. But to do this would be acting prematurely. Unless otherwise compelled to tackle their man, the Scouts were content to let him alone until he had lured Bill and his companions ashore. So, crouching behind the huge boulders that had at some time fallen from the roof of the cave, the lads watched Tassh stealthily make his way towards the entrance. "I wonder if he'll spot Mr Buckley," thought Simpson. But the Scoutmaster was too wary for that. He had clambered upon a narrow ledge seven feet above the main path, whence he could command a view of the cave and the sea as well as the misty starlight would permit. "Oh, there you are, my fine fellow," muttered Mr Buckley, as Tassh, looking anxiously along the main ledge that gave access to the caves, emerged into the open, utterly ignorant of the fact that seven of the "Otters" were within ten yards of him and that a few inches above his head the Scoutmaster had him under observation. Still Tassh hesitated. He even walked a few paces along the ledge, and scanned the rugged cliffs above his head. At length, drawing a portable electric lamp from his pocket, he flashed it twice in quick succession in the direction of the yacht.
