Rodolph chose for himself and the archer two rooms at the top of the southern tower, one above the other, John Surrey occupying the lower. The narrow stone stair which gave access to both rooms ended at the circular flat roof of the tower, a platform protected by a machicolated parapet. The flagstaff of the castle rose from the centre of this platform, and over the parapet one had a broad view, which included hilltop and high level plain, for the summit of the south tower was the highest spot in all the Moselle district. From this lofty perch the weak point of the castle was easily recognised. If Thuron was ever to be carried by assault the gate front would probably be the portion to give way.

The builder of the castle had recognised this, and had constructed a gate ridiculously small when contrasted with the great bulk of the castle itself. The entrance was barely wide enough to allow a cart or two horsemen abreast to pass in. The flattened Norman arch above it supported masonry pierced for the crossbow bolts that might be launched in its defence, and the flat parapet-protected platform over the gate might be covered with warriors, while a huge catapult lay there ready to hurl round stones on whoever attacked the portal. Even if the two stout oaken leaves of the gate, iron bolted, and barred within by heavy timbers, were broken down, the gateway might be held by two expert swordsmen against an outside host. So when the assault was made the souls of many of the besiegers would pass through the gates of Paradise before the bodies of their comrades won their way through the gates of Thuron. Nevertheless, the entrance was the weak point of the castle, for in front of it lay comparatively level ground, while everywhere else the slopes fell steeply from the walls, and the man who attacks up a hill is ever at a disadvantage when he meets the defender who is already on the top. The gate was at the south-western corner of the castle, facing the south. The south tower stood on the eastern face of the fortress twenty yards or less north of the south-eastern corner of the stronghold.

Rodolph came to the conclusion that when the gate was attacked, John Surrey, stationed on the lofty platform of the south tower, with a bundle of arrows at his side, would give a good account of himself, and make some of the besiegers wish they had been elsewhere.

The Emperor, leaving Surrey in his lofty eyrie, went down the stone steps, and endeavoured to send a message to the Countess that he wished to have a word with her. The wholesale deportation of the servants made the carrying of intelligence about the castle difficult, and he, on personal investigation, found the door to the women's apartments barred. Entering the inner courtyard, which was in darkness, for the moon which had been at the full a week before was now on the wane and had not yet risen, he groped his way until he estimated that the balcony was above him, and there softly cried his lady's name, but without receiving any response. No light shone in any of the windows, and a vague alarm filled his breast, not knowing what the Countess might have done in her despair. That she could have left the castle was hardly possible, for the guard was now most vigilant, yet it might be that she had slipped away when the others were taken to Alken, although, as Rodolph had conducted her from the grand saal to the door of the women's apartments, he had imagined that the women and old men were already gone, the last to depart being Hilda herself, who had been taken to the outer courtyard by Captain Steinmetz after the stormy interview in the great hall. The Emperor left the courtyard and returned with a lighted torch, which he placed in a holder set against the wall on the side opposite to the windows, and this with its sputtering resinous flame illuminated the neglected garden, on which Tekla's horticultural efforts had not yet made visible impression. The light had the effect Rodolph desired. The curtains at the back of the balcony parted, and the Countess, wrapped in a long white robe, looking, Rodolph thought, like an angel, came to the edge of the stone coping. The rays of the torch showed her eyes still wet with tears, but their swimming brightness seemed more beautiful than ever. The young Emperor caught his breath with delight on seeing the fair vision before and above him, standing out in pure dazzling white against the grim grey walls of the castle. He tried to speak, but could not trust his voice.

"Is it you, my Lord Rodolph?" asked the Countess, in her low, rich voice, peering into the semidarkness of the garden.

"Yes, Lady Tekla," said the young man, at last finding utterance. "I could not go to rest without having a word with you. Your door was barred and I could get no one to hear me, so I called fire to the aid of my impatience, and set up a torch before your windows."

"We are self-made prisoners. I myself barred the door and paid no heed to the knocking, for I thought it was my uncle returned again. He came once and demanded admittance, which I refused. Then to our amazement he went quietly away, when we fully expected he would batter down the door. My aunt is prostrate with fear of him, and I have but now left her bedside, where she has at last fallen into an exhausted sleep. Oh! why," cried the Countess, raising her arm as if in appeal to a just heaven, "are such uncivilised wretches as the master of Thuron allowed to live and contaminate this fair earth?"

"Well," said Rodolph, with a smile, happily unseen by the girl, who was intensely in earnest, "we must admit that the Archbishops are doing their best to eliminate him. I have often thought that it is only our wonderful self-conceit that leads us to suppose we are actually enlightened beings, and I fear that perhaps future ages may look back on the thirteenth century, and deny to it the proud pre-eminence in civilisation it now so confidently claims. But I have had some conference with your uncle since I last saw you, and I think you will have nothing now to fear from him. There will be no more scenes such as that of this afternoon. He has promised me as much."

"Promised!" cried the girl, indignantly; "I put little faith in his promises."
