“Didst thou slay him, then?”

“Nay, it was the hand of God; and I am free from blood-guiltiness:” and Cuthbert told the whole story, which we need not say Sir Walter heard with intense interest.

“Poor lad! we will pray for his soul as he desired; Sir John has a heavy reckoning before him;—I wonder where he is now! But, my son, to our task; the night wears on.”

Cuthbert well remembered the directions which the Abbot had given him; he had written them and conned them again and again during the intervening years. Amongst the cunning carving which yet ornamented the wainscotting of the ruined chamber, he felt for the rose which was fourth in order from the outer door, and third from the floor; he pressed the centre of the bud sharply with his thumb, and the old broken bookcase, which had been left as a fixture, not worth removing, but broken in mere wantonness, suddenly flew open in the manner of a door.

How near the enemy must have been to the secret, yet the door, which was the back of the bookcase, was ponderous, and the bolt only yielded to the spring, which was released by the pressure upon the carved rose many feet away.

Thirty steps they descended, after fastening the upper door behind them, and below the very foundations, came upon the iron one. Cuthbert touched the spring and it slowly opened.

“We must fasten it carefully back,” said the youth as they stood without, “by this bolt at the bottom, which falls into the pavement close to the adjacent wall; for did it swing to when we were within, we should never get out till the day of doom; it shuts with a spring, and can only be opened from without.”

As he spoke he set the heavy door carefully back, as yet unsecured, against the wall; they watched it with curiosity; at first it appeared to stand still, then began slowly to move, increased speed in going, and shut with a loud resonant clang.

“So it was doubtless contrived in order to catch any unauthorized intruder upon the secrets of the Abbey, who had not observed the bolt and its purpose,” said Father Ambrose. “Secure it carefully, my son.”

Cuthbert did so, and they entered the vault; and now the youth drew the key, which he had kept all these long years, from the pocket in his vest; he inserted it in the lock, the rusty wards turned with difficulty, but with a little force yielded, and they raised the ponderous lid until it fell back and rested against the wall.
