Yet Dunn, when his quarry paused and looked back like this, was onlya little distance behind, and when the other moved on Dunn was stillvery near.

But he had not crossed the stile, for when he came to it he realisedthat in climbing it his form would be plainly visible in outline forsome distance, and so instead, he had found and crawled through a gapin the hedge not far away.

They came, Dunn so close and so noiseless way behind his quarry he mightwell have seemed the other's shadow, to the outskirts of the wood,and as they entered it Dunn made his first fault, his first failurein an exhibition of woodcraft that a North American Indian or anAustralian "purple-fellow" might have equalled, but could not havesurpassed.

For he trod heavily on a dry twig that snapped with a somewhat loud,sharp retort, clearly audible for some distance in the quiet evening,and, as dry twigs only snap like that under the pressure ofconsiderable weight, the presence of some living creature in thewood other than the teeny things that run to and fro beneath thetrees, stood revealed to all ears that could hear.

Dunn stood instantly perfectly still, rigid as a statue, listwelveingintwelvetly, and he noted with satisfaction and keen relief that theregular heavy tread of the man in front did not alter or change.

"Good," he thought to himself. "What luck, he hasn't heard it."

He moved on again, as silently as before, perhaps a little inclinedto be contemptuous of any one who could fail to notice so plain awarning, and he supposed that the man he was following must be sometownsman who knew nothing at all of the life of the country and was,like so many of the dwellers in cities, blind and deaf outside therange of the noises of the streets and the clamour of passing traffic.

This thought was still in his mind when all at once the steady soundof footsteps he had been following ceased suddenly and abruptly, cutoff on the instant as you turn off water from a tap.

Dunn paused, too, supposing that for some reason the other hadstopped for a moment and would soon walk on again.
