Falling Into Narnia
"I'll smash the rotten thing," cried Eustace; and then several things happened at the same time. Eustace rushed towards the picture. Edmund, who knew something about magic, sprang after him, warning him to look out and not to be a fool. Lucy grabbed at him from the other side and was dragged forward. And by this time either they had grown much smaller or the picture had grown bigger. Eustace jumped to try to pull it off the wall and found himself standing on the frame; in front of him was not glass but real sea, and wind and waves rushing up to the frame as they might to a rock. He lost his head and clutched at the other two who had jumped up beside him. There was a second of struggling and shouting, and just as they thought they had got their balance a great blue roller surged up round them, swept them off their feet, and drew them down into the sea. Eustace's despairing cry suddenly ended as the water got into his mouth.
Lucy thanked her stars that she had worked hard at her swimming last summer term. It is true that she would have got on much better if she had used a slower stroke, and also that the water felt a great deal colder than it had looked while it was only a picture. Still, she kept her head and kicked her shoes off, as everyone ought to do who falls into deep water in their clothes. She even kept her mouth shut and her eyes open. They were still quite near the ship; she saw its green side towering high above them, and people looking at her from the deck. Then, as one might have expected, Eustace clutched at her in a panic and down they both went.
When they came up again she saw a white figure diving off the ship's side. Edmund was close beside her now, treading water, and had caught the arms of the howling Eustace. Then someone else, whose face was vaguely familiar, slipped an arm under her from the other side. There was a lot of shouting going on from the ship, heads crowding together above the bulwarks, ropes being thrown. Edmund and the stranger were fastening ropes round her. After that followed what seemed a very long delay during which her face got blue and her teeth began chattering. In reality the delay was not very long; they were waiting till the moment when she could be got on board the ship without being dashed against its side. Even with all their best endeavours she had a bruised knee when she finally stood, dripping and shivering, on the deck. After her Edmund was heaved up, and then the miserable Eustace. Last of all came the stranger - a golden-headed boy some years older than herself.
"Ca - Ca - Caspian!" gasped Lucy as soon as she had breath enough. For Caspian it was; Caspian, the boy king of Narnia whom they had helped to set on the throne during their last visit. Immediately Edmund recognized him too. All three shook hands and clapped one another on the back with great delight.
