It happened that Rogue Riderhood was then working on the river that flowed past the village, where he tended a lock. The schoolmaster, in order to turn suspicion from himself in case any one should see him when he did this wicked deed, observing carefully how Riderhood was dressed, got himself clothes exactly like the lock tender's, even to a red handkerchief tied around his neck. In this guise, with murder in his heart, he lay in wait along the riverside till Wrayburn passed one evening just after he had bade good night to Lizzie Hexam. The schoolmaster crept up close behind the lawyer and struck him a fearful crashing blow on the head with a club. Wrayburn grappled with him, but Headstone struck again and again with the bloody weapon, and still again as the other lay prostrate at his feet, and dragging the body to the bank, threw it into the river. Then he fled. Lizzie Hexam had not yet turned homeward from the riverside. She heard through the night the sound of the blows, the faint moan and the splash. She ran to the spot, saw the trampled grass, and, looking across the water, saw a bloody face drifting away. She ran to launch a boat, and rowed with all her strength to overtake it. But for her dreadful life on the river with her father she could not have found the drowning man in the darkness, but she did, and then she saw it was the man she loved. One terrible cry she uttered, then rowed with desperate strokes to the shore and with superhuman strength carried him to a near-by inn. Wrayburn was not dead, but was dreadfully disfigured. For many days he hovered between life and death. Jennie Wren, the dolls' dressmaker, came, and she and Lizzie nursed him. As soon as he could speak he made them understand that before he died he wanted Lizzie to marry him. A minister was sent for, and with him came John Rokesmith and Bella. So the sick man was married to Lizzie, and from that hour he began to get better, till before long they knew that he would recover. Meanwhile, not waiting to see the result of his murderous attack, Headstone had fled down the river bank to the hut where Riderhood lived and there the villainous lock tender let him rest and sleep. As the schoolmaster tossed in his guilty slumber, Riderhood noted that his clothes were like his own. He unbuttoned the sleeping man's jacket, saw the red handkerchief, and, having heard from a passing boatman of the attempted murder, he guessed that Headstone had done it and saw how he had plotted to lay the crime on him. When the schoolmaster went away Riderhood followed him, watched him change clothes in the bushes and rescued the bloody garments the other threw away. With these in his hands he faced the schoolmaster one day in his class room and made him promise, under threat of exposure, to come that night to the hut by the lock. Headstone was afraid to disobey. When he came, Riderhood told him he must give him money at once or he would follow him till he did.
