Running straight for some distance, the track at last made a sharp bend to the right, then skirting another hedge parallel with the embankment. The two men were on the point of turning with it when Kenneth, in the rear, happening to look behind him over the hedge, caught sight of a man about half a mile away, coming apparently from the direction of the village where the Rutlands were billeted. Ginger came back at a low call from his companion, and they stood together at the hedge, watching the stranger, careful to keep out of sight themselves. The man drew nearer. He was old and shabbily dressed. A small basket was slung on his back. Every now and again he looked behind as if fearful of being followed. They watched him eagerly, surprised, full of curiosity and suspicion. His path ran along the hedge parallel with the railway, and he was screened by it from the British lines. He came on until he had almost reached the hedge behind which the two Englishmen were posted. At this point there was a wide gap in the hedge that covered him, and he turned off sharply at right angles towards the railway. Kenneth instantly guessed that he had done this to avoid observation through the gap, that he would pass round the end of the hedge near the embankment, and follow the track by which Ginger and he had recently come. As the man turned, Ginger caught Kenneth by the sleeve. His eyes were bright with excitement. He seemed about to speak, but Kenneth hastily clapped a hand over his mouth. Watching the man until he was on the point of turning the corner, Kenneth drew Ginger through a small gap in the hedge parallel with the railway, and they waited there until the stranger came up to it on the track they had just left, and began to walk towards another hedge at right angles to it, which led back to the embankment almost at the spot where they had watched through the night. They followed him quietly. He was on the inner side of the hedge, they on the outer. They saw that he was wading along the ditch towards the railway. At the end of the hedge they stooped and peeped through a gap, to see what was going on within a few feet of them. They heard a low whistle, and were just in time to catch sight of the man disappearing into a culvert that carried the ditch under the embankment. Allowing him time to get through, they crawled through the hedge, up the embankment, over the line, and approaching the culvert from above, established themselves on top of the brickwork at the entrance. They heard voices from below, within the culvert. Kenneth held his revolver ready, Ginger gripped his bayonet. And there they waited for one or other of the men inside to come out.
