“For gracious’ sake!” Bill’s expression left no doubt as to the genuineness of his astonishment. “Old Earwig turned up again, eh?”

“Yes, and from some not very complimentary remarks he made about me, Bill,” continued Jack, “I don’t think he’d be averse to doing me some mischief, if he could.”

“He’d better not try.” Bill doubled his fists pugnaciously.

“The trouble is, I didn’t overhear enough to find out just what his little game is.”

“That’s too bad. It’s a shame we didn’t know his identity earlier. We would have earned the thanks of that English cruiser.”

“We certainly would. De Garros told me that Radwig is accounted a very clever and dangerous man. He has invented explosives and is active in the entire German military movement.”

“By the way, where is de Garros?” asked Bill.

“I don’t know any more than you do. After we left him at the depot in New York on our return from Bar Harbor, I lost sight of him. In fact, things have gone on with such a rush since then, that I haven’t had time to think of him till now. He told me, though, that he would take the first ship possible to France.”

“Well, to get back to old Earwig.”

“Yes.”
