Somewhat to Edgar’s surprise, De Brin made no attempt to force the door, but instead ordered his men to hurl down upon it the piled-up blocks of stone. For some minutes a perfect avalanche of these rolled and bounded down upon the door, and every minute Edgar feared that it would be burst open. In the hope of adding a little to its strength he kept his weight against it, though the shock of each stone jarred him to the bone. At last the well formed by the steps began to be filled, and the jar and shock lessened until but a slight tremor followed as the rocks were still flung down. Soon the work was complete, and the castle end of the passage was blocked by a mass of stone that it would take hours’ work by a score of men to clear away. There was no more to be done there, and with a heavy heart Edgar left the door, and made his way along the tunnel. In the far distance a light had sprung up, and he guessed that Peter had managed to obtain a spark and had lit one of the torches they had been careful to snatch from the wall before they left the upper room. "What was that dreadful noise?" asked Beatrice anxiously, as Edgar joined them. "It echoed along the passage until we thought giants indeed must be battering at the door." "Nay, ’tis worse even than that, Beatrice," replied Edgar solemnly. "They have hurled down stones and walled us in." "Well, is not that good news? They cannot pursue, and if we hasten we shall escape before they can cut off our retreat. Peter telleth me that we are almost through this dreadful passage." "They have already cut off our retreat, Beatrice," replied Edgar. "Like a fool, I have brought thee into nothing but a trap. De Brin taunted me that the farther end was guarded, and I fear ’tis true. I had hoped that ye would all have been out long ere this. What hath delayed thee, Peter? The little chance that once we had hath, I fear, gone for ever. "We came upon some obstruction in the passage, Master Edgar," replied Peter earnestly, "and I dared not go on with the ladies in the darkness, not knowing what pitfalls might lie in wait for us. I stopped to light a torch, and my flint and steel work none too fast in this damp and dismal dungeon. But here is the door, and I see no sentinel." "Was yon great chest the obstruction? Didst open it?" "Nay, I would not stop. Shall I go batter it in?" "Nay, let us press on and test the strength of the guard about this end. Perchance, after all, when the good priest heareth the sound of a conflict, he may bring down some of his men and make an attack. We might then break through. Come, hew down that door." "How stifling is this passage, Edgar!" cried Beatrice appealingly. "The heat is becoming dreadful. Whence cometh it?"
