Tom missed his grip, but he was not going to give up. He scarcely slackened his speed, but, with the momentum he had acquired in racing down the hill, he, too, leaped across the brook. As he landed on the other side he made another grab for the figure, a man, as Tom could now see, but he could make out no features, as the person's hat was pulled down over his face.

The other had put out his foot, and tripped him neatly and, Tom throwing out his hands to save himself in the fall that was inevitable, went splashing into the brook at full length. The unknown, pausing a moment to view what he had done, turned quickly and raced off in the darkness.
