line he had taken was, surely, sufficiently bold to remove from him any suspicion of German birth, or of double-dealing. "Yes, I quite agree," declared Trustram enthusiastically. "We know well enough at the Admiralty that the most confidential information leaks out to the enemy almost daily, and--" "And what can you expect, my dear fellow, when we have so many Germans and naturalised Germans here in our midst?" cried Rodwell, interrupting. "Intern the whole lot--that's my idea." "With that I entirely agree," exclaimed Trustram, of course believing fully in his friend's whole-hearted sincerity.

Rodwell remained thoughtful. Mention of that pocket-book, of which Jerrold had obtained possession, caused him to ponder. That it was in the hands of the
