第二十三章：有些龙是真的怪物(17)

However, as he looked round the underground cavern, Hiccup realised he was still in a serious fix. He was in a glass cavern, underneath the sand, and presumably up there on the surface the tide had come in and so he was underneath the sea as well. How was he going to get out of here? But even as he was looking around at the extraordinary glass cavern, and the tunnels that ran off it, he had a tingling at the back of his head as a thought fell into place. He reached into his fire-suit, and took out the raggedy remains of the map. It was looking a little worse for wear, that map, because like Hiccup himself, it had had rather a hard time of it. It was burnt, torn by poisoned fingernails, and covered in seawater and dragon digestive juices. MAZE OF MIRRORS. Oh for Thor’s sake. The red herring at the top of Grimbeard’s map now seemed to be winking as well as laughing at him. The Jewel was here. Of course it was.
