“Its frailness is deceptive. It is a most wonderful instrument, and I should like to know where it comes from. I thought you had bought it from some armourer and intended me to wear it as a badge of my office. Perhaps it was sent by the Empress. The word ‘loyalty’ seems to indicate that, though how it got into this room and on this table unknown to me is a mystery.”

Elsa shook her head as she studied the weapon and the message critically.

“Her Majesty is more direct than this would indicate. If she had aught to say to you she would say it without ambiguity. Do you intend to wear the dagger as the scroll commands?”

“If I thought it came from the Empress I should, not otherwise.”

“You may be assured some one else has sent it. Perhaps it is intended for me,” and saying this Elsa thrust the blade of the dagger through the thick coil of her hair and turned coquettishly so that her husband might judge of the effect.

“Are you ambitious to set a new fashion to the Court, Elsa?” asked Wilhelm, smiling.

“No; I shall not wear it in public, but I will keep the dagger if I may.”

Thus the incident passed, and Wilhelm gave no more thought to the mysterious warning. His duties left him little time for meditation during the day, but as he returned at night from the barracks his mind reverted once more to the dagger, and he wondered how it came without his knowledge into his private room. His latent suspicion of the Archbishops became aroused again, and he pondered on the possibility of an emissary of theirs placing the document on his table. He had given strict instructions that if any one supposed to be an agent of their lordships presented himself at the gates he was to be permitted to enter the city without hindrance, but instant knowledge of such advent was to be sent to the Commander, which reminded him that he had not seen Gottlieb that day, this able lieutenant having general charge of all the ports. So he resolved to return to the barracks and question his underling regarding the recent admittances. Acting instantly on this determination, he turned quickly and saw before him a man whom he thought he recognised by his outline in the darkness as von Brent, one of the officers of Treves whom he had released, and who had accompanied the Archbishop on his return to that city. The figure, however, gave him no time for a closer inspection, and, although evidently taken by surprise, reversed his direction, making off with speed down the street. Wilhelm, plucking sword from scabbard, pursued no less fleetly. The scanty lighting of the city thoroughfares gave advantage to the fugitive, but Wilhelm’s knowledge of the town was now astonishingly intimate, considering the short time he had been a resident, and his woodlore, applied to the maze of tortuous narrow alleys made him a hunter not easily baffled. He saw the flutter of a cloak as its wearer turned down a narrow lane, and a rapid mental picture of the labyrinth illuminating his mind, Wilhelm took a dozen long strides to a corner and there stood waiting. A few moments later a panting man with cloak streaming behind him came near to transfixing himself on the point of the Commander’s sword. The runner pulled himself up with a gasp and stood breathless and speechless.

“I tender you good-evening, sir,” said Wilhelm, civilly, “and were I not sure of your friendliness, I should take it that you were trying to avoid giving me salutation.”

“I did not recognise you, my Lord, in the darkness.”
