The dim lights certainly seemed to be far out on their left and a little behind them. A couple of rifles cracked faintly, and they heard a bullet sigh and whimper overhead. Closer and with sharper reports half a dozen rifles rap-rapped in answer—but the reports were still well out to their left and behind them.

“Those are German rifles behind us. We’ve left the front line,” said the Lieutenant with sudden conviction. “Struck slanting back. Been following a communication trench. Damn!

Studd without answering dropped suddenly to earth and without hesitation the Lieutenant dropped beside him and flattened down. A long silence, and the question trembling on his lips was broken by a hasty movement from Studd. “Quick, sir—back,” he said, and hurriedly wriggled back and into a shallow hole, the Lieutenant close after him.

There was no need of the question now. Plainly both could hear the squelch of feet, the rustle of clothes, the squeak and click of leather and equipment. Slowly, one by one, a line of men filed past their hiding-place, looming grey and shadowy through the mist, stumbling and slipping so close by that to the Lieutenant it seemed that only one downward glance from one passing figure was needed to discover them. Tumultuous thoughts raced. What should he do if they were discovered? Pass one quick word to Studd to lie still, and jump and run, trusting to draw pursuit after himself and give Studd a chance to escape and report? Or call Studd to run with him, and both chance a bolt back the way they came? The thick mist might help them, but the alarm would spread quickly to the front trench.... Or should he snatch his revolver—he wished he hadn’t put it back in his holster—blaze off all his rounds, yell and make a row, rousing the German trench to fire and disclose the strength holding it? Could he risk movement enough to get his revolver clear? And all the time he was counting the figures that stumbled past—five ... six ... seven ... eight.... Thirty-four he counted and then, just as he was going to move, another lagging two. After that and a long pause he held hurried consultation with Studd.

“They’re moving up the way we came down,” he said. “We’re right off the front line. Must get back. Daren’t keep too close to this trench though. D’you think we can strike across and find the front line about where we crossed?”

“Think so, sir,” answered Studd. “Must work a bit left-handed.”

“Come on then. Keep close together,” and they moved off.

In three minutes the Lieutenant stopped with a smothered curse at the jar of wire caught against his shins. “’Ware wire,” he said, and both stooped and felt at it. “Nippers,” he said. “We must cut through.” He pulled his own nippers out and they started to cut a path. “Tang!” his nippers swinging free of a cut wire struck against another, and on the sound came a sharp word out of the mist ahead of them and apparently at their very feet a guttural question in unmistakable German. Horrified, the Lieutenant stood stiff frozen for a moment, turned sharp and fumbled a way back, his heart thumping and his nerves tingling in anticipation of another challenge or a sudden shot. But there was no further sound, and presently he and Studd were clear of the wire and hurrying as silently as they could away from the danger.

They stopped presently, and the Lieutenant crouched and peered about him. “Now where are we?” he said, and then, as he caught the sound of suppressed chuckling from Studd crouched beside him, “What’s the joke? I don’t see anything specially funny about this job.”

“I was thinkin’ of that Germ back there, sir,” said Studd, and giggled again. “About another two steps an’ we’d have fell fair on top of ’im. Bit of a surprise like for ’im, sir.”
