"No, thanks," said John, this time firmly. "I must be pushing along." He happened to be looking into Cherriton's face as he said this, and something took place on the other's face that startled him—a flame of something like ferocity lit up in the German's eyes, then instantly vanished. After that, however, he made no further attempt to detain John. He came to the end of the little cottage garden as John went away, and watched him as he mounted his bicycle and rode away towards Freshwater. Then he returned to the cottage, closed the door behind him, and, dropping into a chair, took out Mrs. Beecher Monmouth's letter and read it carefully from end to end.

He was still in his chair at the hearth half an hour later when Manwitz knocked at the door, and came in.

"Come in, Manwitz, come in!" said Cherriton, rising. Manwitz had halted in the doorway, and was slowly drawing off his mackintosh. There was a mute expression in his eyes. Cherriton, reading his expression, pointed to a chair at the opposite side of the hearth.

"Sit down, Manwitz; nothing has happened yet; our friend is spending the night with his father, but he has arranged to come over here to see me to-morrow."

Manwitz took a handkerchief from his inner pocket, and mopped his brow.

"It is terrible, Herr Baron! His Excellenz affirms that he has been watching us from the beginning, but in that case how can he explain the sinking of the Polidor?"

"The time for explanations has gone, Manwitz. Treves's discoveries, whatever they are, must not be permitted to check the great work his Excellenz has put his hand to."

For some minutes after that there was silence between the two men; then Manwitz spoke, easing his collar about his fat throat:

"His Excellenz impressed upon me, Herr Baron, the business of Mr. Treves is of the utmost urgency."

"That is understood," Cherriton answered grimly. "But His Excellenz has no wish that I should play the fool and expose myself to unnecessary danger. His Excellenz can rely entirely upon my discretion—and our united capacity to carry out his command, eh, Manwitz?"
