"May God keep him out of the hands of De Maupas!" replied Gertrude feelingly; and Sir John echoed her words with deepest emphasis.

Riding to the limit of the endurance of their horses, Edgar and Peter made rapid progress, and were soon back again in the neighbourhood of Ruthènes. This time they did not ride directly into the village, but, when within a mile or so, led their horses into a thick covert and tied them to a tree. They then set off on foot for the castle, keeping well away from the village.

"Tread silently, Peter, and keep a vigilant watch. I would not that any saw us, especially of those belonging to the castle."

As soon as they came within sight of the castle Edgar gave the signal to stop, and, keeping well out of sight of watchers on the wall, the two young men reconnoitred it eagerly.

"There are more sentinels than ever," said Edgar, after a long and earnest scrutiny. "I feared as much. Well, let us now work round to the tree which masks the entrance to the underground passage. If that way is still open to us, all is well."

"But surely they will have found the keys we left behind in the last scramble up the steps cut within the tree trunk?" asked Peter. "They will have locked the doors, and we shall be barred out."

"Doubtless, but I care not for that so long as there is no watcher posted at the doors. With patience we can win a way through the stoutest barriers. But if a sentinel is there, our hope of a silent entry is gone."

Presently Edgar stopped and looked about him in some perplexity. "'Twas near here, was it not, Peter, that the great tree spread its branches? Nevertheless, I can see nothing of it."

"Yes, 'twas certainly near here, Master Edgar. Yon clump of undergrowth--was it not through that we made our way out of sight and reach of Black Eustace and De Maupas?"
