said the Emperor, with a smile; "but your hurried man would lose some valuable time in filing through these stout bars. He would be a ghost indeed to pass between them."
"Not if he knew their secret."
Saying this, Siegfried laid hold of an iron stanchion, one of two that stood perpendicular on either side of the window-aperture from top to ledge, pressed against the thick stone wall. The stanchion left the stone under Siegfried's efforts, and proved to be shaped like an elongated letter E, with three bolts of equal length that fitted into three holes drilled in the side of the window-opening, one at top and bottom, and the third in the middle. The Baron pushed outward the heavy iron grating, which swung on hinges, pulling from the wall three bars with round loops at the end of each, into which the three bolts had interlocked when the grating was closed, and the E-like stanchion placed in position.
"A most ingenious arrangement," cried the Emperor, "lacking only the rope."
"A rope lies there," said Siegfried, kicking the coil with his foot, where it rested on the floor and had escaped notice in the gathering darkness. "It is fastened to a ring in the wall."
"What a device for a lover!" exclaimed Rodolph.
"It is intended for a man's safety rather than his danger," said Siegfried, with the slightest possible touch of austerity in his voice.
The Emperor laughed.
"Nevertheless," he said, "had I my lady-love in this house, I would prefer that she knew not the secret of this window. But why all these precautions, Baron? They have not been put here because I am your visitor, for I think the grate moved rustily upon its hinges."
"No, the window has been as you see it these many years. I do not know its history. I suspect that my father found it convenient sometimes to slip out of Treves without much ado, for I know he felt safer on occasion in our strong Rhine castle than in this sometimes turbulent city. I have not interfered with the device, although I have seldom had need of it. I even keep up an old custom of our house, disliking change as all my forefathers have done, although I have never profited by it."
"What old custom?"
"The stationing of a sentinel night and day in a small room above where we stand. When he sees a light in yonder house by the river, or hears by night or day the cry of a waterfowl that frequents the upper Rhine, but which is unknown on the Moselle, he instantly comes down to this room, throws open the casement and flings out the rope. Although as I said, I have never had actual need of this method of exit or entrance, I have, nevertheless, tested the vigilance of my servants, and have climbed in hand over hand."
"Another question, Baron, and forgive my curiosity. How is it that you, a noble and a householder in Treves, enter the gates as a silk merchant unchallenged? Surely the Archbishop keeps slack guard."
"Although I know many of those about the Archbishop's Court, I am myself practically unknown. I attend once a year, perhaps, a formal function in Treves, but it is generally supposed I am in my castle on the Rhine, or at Frankfort, which is indeed the case. My house attracts no attention, for it has belonged to my family for centuries. And now, your Majesty, the room adjoining this, and connected with it, I design for your sleeping apartment, and I trust you will rest well there."
"One more question, Siegfried, in punishment for the title you have bestowed upon me; that house by the river – is it also yours?"
"Yes. A small place, but in some respects the complement of this. I keep there a fast horse, and a swift skiff, so that the man in a hurry, of whom I spoke, may betake himself either to the road or the river as best falls in with his humour or necessity."
"By the gods, Baron, and should we find it necessary to enter into a conspiracy against the great Arnold von Isenberg, we are reasonably well provided for any emergency."
"It is said there is nothing entirely useless in this world, Rodolph," answered the other, drily.
The Baron drew in the grating, replaced the three-bolted stanchion, and finally closed the inside shutters. A servant announced dinner, and Rodolph betook himself to his room to prepare for it.
CHAPTER II
THE ARCHER INTRODUCES HIMSELF
The Emperor, having removed the stains of travel, followed his host downstairs to the banquet that had been prepared for him, and both fell to with an appetite sharpened by a long journey. The white wines of the Moselle, supplemented by the vintage of the Saar, speedily drove away all remembrance of the day's fatigue.
After the meal, the Baron, with a re-filled flagon at his elbow, stretched out his legs and enjoyed to the full the consciousness that he had been well fed and was comfortably housed, with nothing more arduous in prospect than an honestly earned night's repose. The young Emperor looked across at this picture of contentment with a twinkle in his eye.
"Siegfried," he said, "I have a fancy for a moonlight stroll."
The Baron drew in his feet and sat bolt upright, an expression of dismay coming into his face. The sigh that followed, truly indicated what he perhaps hesitated to express, that he wished people knew when they were well off. The Emperor laughed heartily and added, "You may not have noticed that the moon was nearly full."
"If I had," said the Baron, "I should merely have thanked heaven for it, resolved to stay indoors and follow her most excellent example. The wine flagon has more attraction for me than the fullest of moons, and I have some rare Rhenish in my cellars regarding which I was about to invite your criticism – a more potent vintage than this of the Saar."
"The Rhenish will be still older when we return, Siegfried."
"Indeed, and that is true, Rodolph. It may have aged so much that our heirs shall have the enjoyment of drinking it. The man who leaves a secure door in Treves to stroll by moonlight has no surety of ever reaching it again. A slit throat is an ill conduit for sound Rhenish."
"Is Treves, then, so turbulent? I thought the Archbishop kept strict rule."
"Much goes on in Treves that the Archbishop knows nothing of, as our own presence here is witness. The town is full of soldiers and bravos. There are many outbreaks in the streets, and a brawl might be fatal to your plans. We should assuredly be stopped and questioned, and we might have to trust to our swords."
"You think then, a jaunt in the country would be safer than a moonlight stroll in the city?"
"I do indeed."
"That tallies exactly with my purpose. Never say again that I disregard your advice, for it is not your secure door I would leave, but your insecure window, trusting to find the rope dangling there when we return. I am anxious to test your ingenious device of exit and entrance. We shall walk to the river, and you will make me free of your boat and your fleet horse. It is well that your servants at that small house on the Moselle should know me, for if I enact the part of your man in a hurry, it would avail me little to scramble down the city wall, while you bravely kept the outer door with your sword against the minions of Arnold, if your own minions by the river refused further means of escape."
"That is true, but we are safe here for the night and may we not without prejudice put off further action until to-morrow?"
"There speaks the comforting flagon, Baron. You are too well versed in siege and surprise not to know that every precaution should be taken, and that no moment is too soon for doing what reconnoitering there is to be accomplished. I would not ask you to accompany me, were it not that I need your introduction in the house by the river."
This brought Siegfried instantly to his feet.
"Where you go, I go, introduction or none. Let us then to the window before the night grows older."
They mounted the stairs again, and unbolted the swinging window-grate. The Baron going first, slid swiftly down the rope, and a moment after he reached the ground, the Emperor followed. Directly under the wall, they were in the shadow, but the broad plain before them, and the cliffs beyond, lay distinct in the moonlight. The small riverside hamlet, towards which they bent their steps, showed here and there a few twinkling lights, to guide them. The plain was uncultivated, covered with thick rank grass, which seemed to betoken a marshy nature
