Dacres bowed stiffly. He was still unable to see what his questioner was like, but judging by his voice he was a comparatively young man.

"I think I can claim to be both," he replied. He was now in no hurry to furnish explanations. The situation appealed to him, and the more he could prolong his stay on the forbidden ground the better, he decided. Cranbury House was for the time being far remote from his mind.

"Allow me to show you the way to my modest dwelling," continued the unknown. "There is no need for you to hurry away."

Whether there was any significance in the latter sentence Dacres could not quite determine. He cared still less, for here, apparently, was a chance of learning more about the owner of this mysterious airship.

After giving various directions to his men, the stranger took hold of Dacres' arm in an easy yet dignified manner.

"Now," he said, "this way. It is rather a rough path."

"It couldn't be rougher than the path I traversed this evening," said Dacres, but the remark drew no response from his self-constituted companion.

The track seemed a perfect labyrinth. It wound in sharp curves between the thickly-clustered trees; sometimes ascending and sometimes dipping steeply into hollows crowded with dense undergrowth. The darkness under the foliage was intense, and without his companions guiding arm Dacres must have collided with the tree trunks more than once; but the stranger seemed to possess the instincts of a cat, for unhaltingly he pursued his way with the certainty of a man familiar with his haunts.

Presently the two men came upon a road that cut its way boldly through the wood. This the stranger followed for about a hundred yards, till he stopped in front of a gateway in a tall brick wall.

Had Dacres wished to escape there seemed no reason why he should not take to his heels, for the roadway was evidently a carriage-drive, and must lead somewhere. But without hesitation he complied with the unknown's unspoken request as, with a wave of the hand, he indicated that his guest should enter.
