"Aye, and will again," laughed the officer, twirling his moustache.

Baron Siegfried von Brunfels now led the way through a narrow street, riding confidently, like a man well acquainted with his direction. Avoiding the main thoroughfare which led to the north gate, he turned into what seemed little more than a lane, and now the horsemen were compelled to travel in file, as the way was not broad enough for two horses conveniently to walk abreast. Neither were there houses on each side, as was the case with the street they had just left, but instead, blank walls, such as might surround convents or monasteries, as indeed they did. So high were these enclosing barriers, that Rodolph on his horse could not see over them, and he had the feeling of a man making his way along the deep bottom of a huge ditch, which impression was intensified by the gathering gloom of approaching night. The lane, continually bending toward the right of the riders, came at last to what was quite evidently the city wall, and on this abutted the lesser wall of the monastery grounds on the right, while that on the left ran for some distance parallel to the more lofty ring of stout masonry which encircled the city, leaving a narrow space between. The ringing sound of the iron-shod hoofs on the stone causeway echoed from the ramparts in the deep stillness. In the distance a large mansion built against the city wall, stood across the way and ended the lane. The windows were shuttered and heavily barred with iron, giving the building a forbidding, prison-like appearance. The lane terminated at a strong arched gate, with heavy double doors of oak, iron-bolted, in one leaf of which was a shuttered grating that, being lifted, enabled those within to see all who approached. The bastion to the left ended against the side of this sinister house.

"By the gods, Baron," cried the Emperor, "it is well I have confidence in you, for never was man guided along a more death-trap road to such a sepulchre-looking ending. What fortress have we here, Siegfried? This is no inn, surely."

The Baron half turned in his saddle, and spoke in a voice so low that its tone alone was a hint against unnecessary conversation.

"It is my house," he said. "You will be better served and less spied upon than at an inn."

A moment later the Baron, stopping at the archway, but without dismounting, reached out his hand and pulled an iron rod which had a loop lower down for the convenience of one on foot. The faint clanging of a bell, jangling far within, could be heard. After the echoes died away there was a perceptible interval, then the shutter behind the grating was noiselessly lifted with some caution, and a pair of eyes appeared and disappeared at the iron network. Instantly the gates were flung open and were as speedily closed when the horsemen had ridden into a courtyard.

Having parted with their tired steeds, host and guest, hardly less weary with their ride, mounted one broad stairway and two narrower ones, then walked along a passage that led them to a door, on opening which, Siegfried conducted the Emperor into a large square apartment lighted by two windows heavily barred outside. The inside shutters were open, and Rodolph looked over an extensive landscape bounded by red cliffs and green hills, at the foot of which flowed the rapid Moselle. Although the sun had gone down and the view was growing indistinct in the twilight, Rodolph went to one of the windows and gazed admiringly upon the prospect. The moon, nearly at the full, had risen, and was already flooding the scene with her silvery light.

"You have a pleasant outlook here, Siegfried," said the Emperor.

"Yes, and a safe one."

"A safe one?" echoed Rodolph, inquiringly.
