It was merely the effect of an alarmed imagination, and he told himself to ride straight on, looking ahead, not back.

But reason again yielded to instinct and he curved once more into the deep forest, where the tangle of vines and undergrowth also was so thick that it would take a keen eye to find him.
Dick looked back along the path which he had come and he was confident that he saw some of the tall bushes shake a little.

It could not be wind, because the air was absolutely still, and soon he was convinced that his instinct had been right all the time.

Fancy had played him no trick and the shadow that he had seen was a human figure.
He felt with all the force of conviction that he was in great danger, but he did not know what to do.

So he did nothing, but sat quietly on his horse among the bushes.
