“The letters ‘S. S. G. G.’ stand for Strick, Stein, Gras, Grün: Strick meaning, it is said, the rope which hangs you; Stein, the stone at the head of your grave, and Gras, Grün, the green grass covering it.”

“Well, your Majesty,” said Wilhelm, picking up the parchment from the floor and tearing it in small pieces, “if I have to choose between the rope and the dagger, I freely give my preference to the latter. I shall not attend this secret conclave, and if any of its members think to strike a dagger through my heart, he will have to come within the radius of my sword to do so.”

“God watch over you,” said the Empress fervently, “for this is a case in which the protection of an earthly throne is of little avail. And remember, Lord Wilhelm, trust not even your most intimate friend within arm’s length of you. The only persons who may not become members of this dread order are a Jew, an outlaw, an infidel, a woman, a servant, a priest, or a person excommunicated.”

Wilhelm escorted the Empress to the door of the red room, and there took leave of her; he being unable to suggest anything that might assuage her anxiety regarding her husband, she being unable to protect him from the new danger that threatened. Wilhelm was as brave as any man need be, and in a fair fight was content to take whatever odds came, but now he was confronted by a subtle invisible peril, against which ordinary courage was futile. An unaccustomed shiver chilled him as the palace sentinel, in the gathering gloom of the corridor, raised his hand swiftly to his helmet in salute. He passed slowly down the steps of the palace into the almost deserted square in front of it, for the citizens of Frankfort found it expedient to get early indoors when darkness fell. The young man found himself glancing furtively from right to left, starting at every shadow and scrutinising every passerby who was innocently hurrying to his own home. The name “Fehmgerichte” kept repeating itself in his brain like an incantation. He took the middle of the square and hesitated when he came to the narrow street down which his way lay. At the street corner he paused, laid his hand on the hilt of his sword and drew a deep breath.

“Is it possible,” he muttered to himself, “that I am afraid? Am I at heart a coward? By the cross which is my protection,” he cried, “if they wish to try their poniarding, they shall have an opportunity!”

And drawing his sword he plunged into the dark and narrow street, his footsteps ringing defiantly in the silence on the stone beneath him as he strode resolutely along. He passed rapidly through the city until he came to the northern gate. Here accosting his warders and being assured that all was well, he took the street which, bending like a bow, followed the wall until it came to the river. Once or twice he stopped, thinking himself followed, but the darkness was now so impenetrable that even if a pursuer had been behind him he was safe from detection if he kept step with his victim and paused when he did. The street widened as it approached the river, and Wilhelm became convinced that some one was treading in his footsteps. Clasping his sword hilt more firmly in his hand he wheeled about with unexpectedness that evidently took his follower by surprise, for he dashed across the street and sped fleetly towards the river. The glimpse Wilhelm got of him in the open space between the houses made him sure that he was once more on the track of von Brent, the emissary of Treves. The tables were now turned, the pursuer being the pursued, and Wilhelm set his teeth, resolved to put a sudden end to this continued espionage. Von Brent evidently remembered his former interception, and now kept a straight course. Trusting to the swiftness of his heels, he uttered no cry, but directed all his energies toward flight, and Wilhelm, equally silent, followed as rapidly.

Coming to the river, von Brent turned to the east, keeping in the middle of the thoroughfare. On the left hand side was a row of houses, on the right flowed the rapid Main. Some hundreds of yards further up there were houses on both sides of the street, and as the water of the river flowed against the walls of the houses to the right, Wilhelm knew there could be no escape that way. Surmising that his victim kept the middle of the street in order to baffle the man at his heels, puzzling him as to which direction the fugitive intended to bolt, Wilhelm, not to be deluded by such a device, ran close to the houses on the left, knowing that if von Brent turned to the right he would be speedily stopped by the Main. The race promised to reach a sudden conclusion, for Wilhelm was perceptibly gaining on his adversary, when coming to the first house by the river the latter swerved suddenly, jumped to a door, pushed it open and was inside in the twinkling of an eye, but only barely in time to miss the sword thrust that followed him. Quick as thought Wilhelm placed his foot in such a position that the door could not be closed. Then setting his shoulder to the panels, he forced it open in spite of the resistance behind it. Opposition thus overborne by superior strength, Wilhelm heard the clatter of von Brent’s footsteps down the dark passage, and next instant the door was closed with a bang, and it seemed to the young man that the house had collapsed upon him. He heard his sword snap and felt it break beneath him, and he was gagged and bound before he could raise a hand to help himself. Then when it was too late, he realised that he had allowed the heat and fervour of pursuit to overwhelm his judgment, and had jumped straight into the trap prepared for him. Von Brent returned with a lantern in his hand and a smile on his face, breathing quickly after his exertions. Wilhelm, huddled in a corner, saw a dozen stalwart ruffians grouped around him, most of them masked, but two or three with faces bare, their coverings having come off in the struggle. These slipped quickly out of sight, behind the others, as if not wishing to give clue for future recognition.

“Well, my Lord,” said von Brent, smiling, “you see that gagging and binding is a game that two may play at.”

There was no reply to this, first, because Wilhelm was temporarily in a speechless condition, and, second, because the proposition was not one to be contradicted.

“Take him to the Commitment Room,” commanded von Brent.
