"Then a thundering good job I did plug the Hun!" declared the sub vehemently. He was not vindictive by nature, but the thought of being in danger of being ambushed and shot down by a skulking assassin riled him. "Better be moving, I suppose? If you'll carry one gun I'll tackle the others. Those rabbits? Yes, I'll bring them along. Poor little beasts; fancy being laid out by the same charge of shot that kippered the Boche spy. Horribly degrading for poor bunny. I say, rummy spot for a spy, isn't it? Did he have an inkling that you were on his track?"

"One cannot tell," replied Entwistle. "My theory is that he was making for a certain cottage, where, from information received, I know the fellow had previously obtained a quantity of explosives. I mean to collar those fellows this afternoon. The time's ripe."

"Single-handed?" inquired the sub.

"If necessary."

"I'd like to have a cut in with you, Entwistle," said Farrar impetuously.

"It's hardly your job," rejoined the Secret Service man dubiously. "There may be a tough sort of scrap."

"In which case two are better than one——"

"Provided each knows his job and doesn't bungle," added Entwistle. "All right, then; it's a bargain. Not a word to the others, mind. I am keeping my friend Peter quite in the dark. Do you understand an automatic?"

"Most makes," admitted the sub.

"Then have this," said his companion, handing him the weapon belonging to the Hun. "I've taken the precaution to set the safety-catch."
