“Don’t you like his mouth and chin? It’s a strong chin and I like those well-shaped sensitive lips.”

“Yes, but I think the eyes are more striking.”

“It’s no good, though, having a knight at all, certainly not a peasant-knight,” said Audry roguishly, “unless he has nice lips.”

Aline smiled. “You’re getting frivolous. Now be serious, we have a great deal to do.”

They reached the Hall, ran up to their bedroom and before they started on their further explorations Aline took out the book so as to be prepared for emergencies. She read on for some time and discovered several things, one was the way to open the trap door that led into the cave and especially the way that it could be made to open from the outside if the inner bolts were not fastened. Another important discovery was that the door of their room could be locked by an ingenious bolt in the secret stairway, that pushed back from the bolt-hole into the lock itself. This enabled any one to leave the room unlocked when away, so as to excite no suspicion. Yet on returning, after seeing that the room was empty, by peering through a small slit, one could, by locking the door, make sure that one would not be caught by any one entering the room at the same moment. The children again made their way down the stairs to the secret room where they paused a few moments to look at things for which there was not time on the previous occasion. There were several cupboards, one of which had stone shelves and was clearly intended for a larder. There was amongst other things a large iron chest, which did not seem to have any lock and which greatly excited their curiosity. In another chest they found several pistols and swords besides a few foils and some fencing masks. There were also some tools and some rope and a whole wardrobe of clothes of many kinds. Most of the things were very old but a certain number were comparatively recent. At the same time there was nothing to indicate that the room had been used for the last twenty years.

“Come, we must not stay looking at these things, however interesting,” said Aline; “we must be getting on. But I am glad there is a nice place to keep food; only we shall have a great difficulty in getting a supply.”

She opened a little door as she spoke and once more they found themselves in a narrow passage that led down a flight of steps. It turned abruptly to the right at the bottom of the steps and then went absolutely straight for what seemed to them an interminable length. It was only the thought of the wounded man that prevented them from turning back. There was a little drain at the bottom of the passage and the whole sloped slightly so that the water that percolated freely through the walls was carried off.

At last they reached the end, where the passage terminated in a short flight of stairs. At the bottom of the stairs was a basin hollowed in the rock and this was fed by a spring of delicious water. They went up these and found a curious door made of stone. It was fastened with huge wooden bolts, a precaution, as they afterwards guessed, against rust. They passed through and discovered that the other side of the door was quite irregular and rough and the chamber in which they found themselves, if chamber it could be called, was like a natural cave. In the middle of the rocky floor was a great stone. Even this looked natural although they found that, as the book had said, it was so cunningly shaped and balanced that it would swing into a vertical position without much effort and allow of a man dropping through on one side of it. But the clever part of it was,—that what looked like accidental breaks in the stone were so arranged that certain other blocks could be fitted into them and the surrounding rock so that it could not be moved. If then by any accident any one should make his way into the chamber he would only think that he had come into a natural cave. Audry let herself down through the hole and with the help of Aline dropped to the ground, and found herself in a small fissure or cave, more or less blocked by underwood, where the stream ran through a little hollow or gully. She succeeded in getting back after making several unsuccessful attempts.

“It is an excellent place,” said Audry, “but however shall we get him through that passage, it is so very narrow and so terribly long.”

“We might even have to leave him in the cave room to-night,” Aline replied, “but I think it would be a good idea to count our steps on the way back. It will be interesting to know how long it is, and we shall also be able to tell in future how far we are at any moment from the end.”
