Jim Braid was in two minds what to do, and was even about to show himself to the stranger and ask his business, when the front door of the house opened, and he made out the figure of Captain von Hardenberg silhouetted against the light in the hall. Jim had no particular desire to eavesdrop. Still, as we know, he disliked and mistrusted the Prussian; and, besides, the secretive manner in which the stranger was careful to keep in the shadow of the trees had already aroused his suspicions.

When the man with the white hat saw von Hardenberg, he whistled softly, and went forward a little towards him. They met a few yards from where Jim Braid was hiding. The stranger at once held out a hand. Von Hardenberg refused to take it.

"I knew you'd come here," said he. "Can't you leave me alone?"

"You're four months overdue, Captain von Hardenberg," answered the other. "My interest is increasing day by day. You owe me nearly four thousand pounds!"

"Well, I can't pay," said von Hardenberg. "And there's an end of it."

"Captain von Hardenberg," said the man, who spoke English with a strong German accent. "I am sick of you. In a word, I have found you out. You desire the services of a spy—one who has access to valuable information—and you come to me, Peter Klein, even myself, who as the butler of a cabinet minister have many opportunities of reading letters and overhearing the consultations of those who are suppose to govern these sleepy, fog-begotten islands. You are paid from Berlin, and you are paid to pay me. And what do you do with the money? Gamble. In a word, you play cards and lose money which by right is mine, which I—not you—have earned. Then you beseech me to hold my tongue, promising me that you will repay me with interest as soon as ever you have inherited your uncle's estates. This, I find, is a lie. Your uncle has another nephew, just as likely to inherit his capital as you. You play with me. But I hold you in the hollow of my hand. Remember, I have only to report you to Berlin, and you are ruined, once and for all."

Von Hardenberg was silent for some moments. Then he spoke in a quick, jerky voice.

"Look here," said he; "it's no good. This very evening, knowing that you were coming, I made a clean breast of it to my uncle. I told him that I was four thousand pounds in debt to a money-lender, and that, if I couldn't pay, you would come down upon me. I suppose you don't mind that. I couldn't tell him you were a Government spy disguised as a butler in a private house. And what do you think he said?"

"I have not the least idea," said the other.

"He told me," said von Hardenberg, "that he would cut me off with a shilling!"
