THE
LONG LADDER

VERY fortress has one traitor within its walls; the Schloss Eltz had two. In this, curiously enough, lay its salvation; for as some Eastern poisons when mixed neutralize each other and form combined a harmless fluid, so did the two traitors unwittingly counteract, the one upon the other, to the lasting glory of Schloss Eltz, which has never been captured to this day.
It would be difficult to picture the amazement of Heinrich von Richenbach when he sat mute upon his horse at the brow of the wooded heights and for the first time beheld the imposing pile which had been erected by the Count von Eltz. It is startling enough to come suddenly upon a castle where no castle should be; but to find across one's path an erection that could hardly have been the product of other agency than the lamp of Aladdin was stupefying, and Heinrich drew the sunburned back of his hand across his eyes, fearing that they were playing him a trick; and seeing the wondrous vision still before him, he hastily crossed himself, an action performed somewhat clumsily through lack of practice, so that he might ward off enchantment, if, as seemed likely, that mountain of pinnacles was the work of the devil, and not placed there, stone on stone, by the hand of man. But in spite of crossing and the clearing of the eyes, Eltz Castle remained firmly seated on its stool of rock, and, when his first astonishment had somewhat abated, Von Richenbach, who was a most practical man, began to realize that here, purely by a piece of unbelievable good luck, he had stumbled on the very secret he had been sent to unravel, the solving of which he had given up in despair, returning empty-handed to his grim master, the redoubtable Archbishop Baldwin of Treves.
It was now almost two months since the archbishop had sent him on the mission to the Rhine from which he was returning as wise as he went, well knowing that a void budget would procure him scant welcome from his imperious master. Here, at least, was important matter for the warlike Elector's stern consideration—an apparently impregnable fortress secretly built in the very center of the archbishop's domain; and knowing that the Count von Eltz claimed at least partial jurisdiction over this district, more especially that portion known as the Eltz-thal, in the middle of which this mysterious citadel had been erected, Heinrich rightly surmised that its construction had been the work of this ancient enemy of the archbishop.
Two months before, or nearly so, Heinrich von Richenbach had been summoned into the presence of the Lion of Treves at his palace in that venerable city. When Baldwin had dismissed all within the room save only Von Richenbach, the august prelate said:
"It is my pleasure that you at once take horse and proceed to my city of Mayence on the Rhine, where I am governor.
