"Then what's this?"
Malcolm examined the clothing. Not only was there a coat, but a New Zealander's complete kit.
"By Jove," he exclaimed, "I have it! That's the uniform the spy fellow was wearing. He must have come here, knowing that this dug-out was the Hun brigade head-quarters, and changed into a Boche rig-out. Ten to one he was amongst that lot of staff officers."
"If so, he's properly done in," added Selwyn.
The two chums were only partly correct in their surmise. Konrad von Feldoffer, on realizing that he had been recognized by a couple of men who, he thought, belonged to another battalion, had rather prematurely bolted for the German lines. In the guise of a New Zealander he had been hoping to gather useful and definite information concerning the forthcoming advance. Since most of the Diggers were in ignorance of the mining operations under Messines Ridge, von Feldoffer gained very little information on that point.
By means of a pre-arranged signal the spy arrived at the German trenches without being fired on by his compatriots, despite his khaki uniform and British-pattern shrapnel-helmet. Taken to the head-quarters' dug-out, he made his report to the Hun authorities, changed into German uniform, and left immediately afterwards for a new sphere of activity. So, once more, by the matter of a few hours, Konrad von Feldoffer escaped a well-merited death; while, through ignorance of the terrific preparations made for the blowing up of Messines Ridge, he had unwittingly done the Allies a good turn; for instead of withdrawing the troops the Hun commander had concentrated a thousand on the mined ridge in order to repel an infantry attack that threatened only in the minds of the German staff.
"What are you fellows doing?" enquired Malcolm of the Australian. "Demolishing dug-outs?"
"Not much," replied Kennedy. "We are not raiding this time. We're here to hold what we've got, not to do as much damage as we can and return to our own lines. Already our heavies are well up. A battery of 14-inch guns is in a position just behind the original first-line Boche trench. The air is positively stiff with aeroplanes--all British. The Hun airmen take jolly good care to give us a miss. They absolutely funk it."
"Don't blame 'em!" added another Anzac. "We're top dog in the air just now."
Taking the discarded uniform for identification purposes, Malcolm proceeded to lead the rescue party on their return journey. The two injured men gave considerable trouble. Joliffe, whose wounds were giving him excruciating pain, showed a decided tendency to become light-headed, while Selwyn was so badly bruised and shaken that he could hardly crawl.
