Wilhelm sprang forward and buried the dagger of the Fehmgerichte into the heart of the man before him. His action was so unexpected that the victim could make no motion to defend himself. So truly was the fierce blow dealt that the doomed man, without a cry or even a groan, sank in his death collapse at the young man’s feet in a heap on the floor.

Wilhelm, who thought little of taking any man’s life in a fair fight, shuddered as he gazed at the helpless bundle at his feet; a moment before, this uncouth heap stood erect, a man like himself, conversing with him, then the swift blow and the resulting huddle of clay.

“Oh, God above me, Over-lord of all, I struck for my King, yet I feel myself an assassin. If I am, indeed, a murderer in Thy sight, wither me where I stand, and crush me to the ground, companion to this dead body.”

For a few moments Wilhelm stood rigid, his face uplifted, listening to the pulsations in his own throat and the strident beatings of his own heart. No bolt from heaven came to answer his supplication. Stooping, he, with some difficulty, drew the poniard from its resting-place. The malignant ingenuity of its construction had caused its needle point to penetrate the chain armour, while its keen double edge cut link after link of the hard steel as it sunk into the victim’s breast. The severed ends of the links now clutched the blade as if to prevent its removal. Not a drop of blood followed its exit, although it had passed directly through the citadel of life itself. Again concealing the weapon within his doublet, a sudden realisation of the necessity for speed overcame the assaulter. He saw before him a means of escape. He had but to don the all-concealing cloak and walk out of this subterranean charnel house by the way he had entered it, if he could but find the foot of the stairs, down which they had carried him. Straightening out the body he pulled the cloak free from it, thus exposing the face to the yellow light of the lantern. His heart stood still as he saw that the man he had killed was no other than that exalted Prince of the Church, the venerable Archbishop of Treves. He drew the body to the pallet of straw in the corner of the cell, and there, lying on its face, he left it. A moment later he was costumed as a high priest of the order of the Fehmgerichte. Taking the lantern in his hand he paused before the closed door. He could not remember whether or not he had heard the bolts shot after the Archbishop had entered. Conning rapidly in his mind the startling change in the situation, he stood there until he had recovered command of himself, resolved that if possible no mistake on his part should now mar his chances of escape, and in this there was no thought of saving his own life, but merely a determination to get once more into the streets of Frankfort, rally his men, penetrate into these subterranean regions, and rescue the Emperor alive. He pushed with all his might against the door, and to his great relief the heavy barrier swung slowly round on its hinges. Once outside he pushed it shut again, and was startled by two guards springing to his assistance, one of them saying:

“Shall we thrust in the bolts, my Lord?”

“Yes,” answered Wilhelm in the low tone which all, costumed as he was, had used. He turned away but was dismayed to find before him two brethren of the order arrayed in like manner to himself, who had evidently been waiting for him.

“What is the result of the conference? Does he consent?”

Rapidly Wilhelm had to readjust events in his own mind to meet this unexpected emergency.

“No,” he replied slowly, “he does not consent, at least, not just at the moment. He has some scruples regarding his loyalty to the Emperor.”

“Those scruples will be speedily removed then, when we remove his Majesty. The other members of the Court are but now awaiting us in the Judgment Chamber. Let us hasten there, and make a quick disposal of the Emperor.”
