"Who, then, is the sergeant responsible?" asked the officer in cold, unsympathetic tones, looking the unfortunate sergeant over from the spike of his Pickelhaube to the thick soles of his regulation boots. "Surely not this sergeant? Surely not the non-commissioned officer before me—the one so quick to find fault with a sentry who seems to have been doing only his duty? Surely not!"

And yet a glance at his face showed well enough that he knew that the culprit stood before him; moreover, that he was determined to make the most of the opportunity.

"I—we—this fool here——" began the Sergeant, spluttering, confused, and now just as thoroughly frightened as had been the victim he had pounced upon such a little time before.

"Stop!" snapped the officer; "you are under arrest; go back to your quarters. Now, my man, you fired your rifle to stop a man from escaping. Narrate the circumstances, and quickly, for, for all I know, the rascal may be even now continuing the attempt."

At that the sentry smiled—smiled boldly too, when he saw the discomfiture of the Sergeant. Turning half-right abruptly, till he faced the entrance of the hut, he pointed towards it, and shook his grizzly head knowingly.

"It was like this, sir," he said, with an air of triumph, "I was passing to and fro on my beat, noting nothing out of the ordinary, until there came a moment when I was opposite this hut, almost on the precise spot on which I am now standing, when I heard sounds which attracted my notice—heavy sounds, the noise of men digging. There was no sergeant in sight, no one responsible for the hut to whom I could appeal, yet a glance within showed me an opening in the floor, covered as a rule by boards, which were now removed. There was a man in the hole, deep down and beyond it, in a tunnel, a man whose figure I could only just discern—a ruffian who was attempting to dig his way from the hut out beyond the wire entanglements. It was then, seeing there was no one here to support me, that I fired my rifle."

"Ha! And the fellow is there still?" demanded the officer quickly.

"Still, your honour, unless he has escaped during the time the Sergeant cross-questioned me; of a truth, he is still there, unless, perhaps, he should have in the meantime, while I was delayed in executing my duty, contrived to clamber out of the opening."

"Close in, you men," bellowed the officer; "half a dozen of you come along with me, and hold your rifles ready. Now, into the hut and let us capture these fellows."

Closing round the entrance to the hovel—termed a hut—in which the unfortunate interned aliens had been forced to live for months, the sentries watched the officer and a few of their comrades push their way into the interior, heard them stamping on the boards, and listened to the peremptory orders of the former.
