"Look here!" began Henri, quite nettled, and becoming increasingly impatient, whereat Jules grinned. Indeed, it was his turn to be amused, for intuitively in the darkness he had guessed at Henri's condition; and knowing already how shaken he was, how nearly on the verge of unconsciousness, he had racked his brain for some method which might revive him. Stimulants, water, food, things of that sort, were out of the question; words alone could be employed, and somehow the clever Jules had contrived to pick the proper subject. The mention of Stuart, then, had helped to revive his friend; and now mention of Henri's gallantry had made the owner of that name quite indignant.

"Utter rot!" shouted Henri again; "as if slinging a bomb was dangerous; and as if——"

"There's one thing you can't deny," said Jules; "it saved my life, as it was designed to do, and I've not forgotten. But how d'you feel? Better, eh? Don't forget that we've lost sight of that German."

As if Henri had ever forgotten it since he had seen the lithe, cunning figure of the Brandenburger creeping in front of him. True, in that curious state in which he had been—a state bordering on unconsciousness—he had hardly been able to appreciate at times the significance of the German's presence; but now he had wakened fully to its importance.

"Jingo," he told Jules as they squatted there in the darkness, "we must find the beggar! He's armed, without a doubt; and, worse than all, he's behind our fellows, for they've gone forward into the fort. What's to prevent him shooting 'em in the back? What's to prevent him carrying on any sort of vileness? We've got to follow at once, and, by hook or by crook, we've got to capture or kill the beggar."

"Whichever you like—either will suit me," Jules responded; "and in any case, if he's caught, it'll come to the same thing. Once we've marched him back behind our lines, and handed him over as a prisoner, he'll be shot, my boy. We can prove that he would have deliberately shot a prisoner; so it seems to me that, if we meet the gentleman, the best thing will be to end the matter promptly. But we've got to find him first, and perhaps he'll have something to say when it comes to a question of shooting."

Max, that sinister Brandenburger officer, was indeed likely enough to have a considerable amount to say in the question of his own disposal. Knowing the class of man he was—his fearlessness, for that seemed to be his one virtue; his frightfulness, for bullying and terrible deeds seemed to be the characteristic of every subject of the Kaiser—it was likely enough that this fellow would do anything to outwit the Frenchmen, and, if he could, would shatter the fort and bring it down upon his own head rather than see the French victorious.

"Stop! Wait a moment! I heard something move! Come on!" said Jules suddenly.

And together, creeping on hands and knees, the two went forward along that gallery in search of the German.
