“At the cathedral, from the man Niburg.”

“You lie!” said Karl. Then, for a moment, he left Nikky and turned on his companion in a fury. He let his royal rage beat on that unlucky individual while the agent stood, white and still. Not until it was over, and Karl, spent with passion, was pacing the floor, did Nikky venture a word.

“If this is not what Your Majesty expected,” he said, “there is perhaps an explanation.”

Karl wheeled on him. “Explanation!”

“The man Niburg was attacked, early last evening, by three men. They beat him badly, and attempted to rob him. His story to me, sire. He believed that they were after the letter, but that he had preserved it. It is, of course, a possibility that, while he lay stunned, they substituted another envelope for the one he carried.”

Karl tore the envelope from the agent’s hands and inspected it carefully. Evidently, as with the agent, the story started a new train of thought. Nikky drew a long breath. After all, there was still hope that the early morning shooting would have another target than himself.

Karl sat down, and his face relaxed. It was stern, but no longer horrible. “Tell me this Niburg’s story,” he commanded.

“He was walking through the old city,” Nikky commenced, “when three men fell on him. One, a large one, knocked him insensible and then went through his pockets. The others—”

“Strange!” said Karl. “If he was insensible, how does he know all this?”

“It was his story, sire,” Nikky explained. But he colored. “A companion, who was with him, ran away.”
