Dumbledore had convinced Harry not to go looking for the Mirrorof Erised again, and for the rest of the Christmas holidays theinvisibility cloak stayed folded at the bottom of his trunk. Harrywished he could forget what he'd seen in the mirror as easily, buthe couldn't. He started having nightmares. Over and over again hedreamed about his parents disappearing in a flash of green light,while a high voice cackled with laughter. "You see, Dumbledore was right, that mirror could drive you mad,"said Ron, when Harry told him about these drearns. Hermione, who came back the day before term started, took adifferent view of things. She was torn between horror at the ideaof Harry being out of bed, roaming the school three nights in a row("If Filch had caught you!"), and disappointment that he hadn't atleast found out who Nicolas Flamel was. They had almost given up hope of ever finding Flamel in a li-brary book, even though Harry was still sure he'd read the namesomewhere. Once term had started, they were back to skimming throughbooks for ten minutes during their breaks. Harry had even less timethan the other two, because Quidditch practice had started again. Wood was working the team harder than ever. Even the endlessrain that had replaced the snow couldn't dampen his spirits. TheWeasleys complained that Wood was becoming a fanatic, but Harry wason Wood's side. If they won their next match, against Hufflepuff,they would overtake Slytherin in the house championship for the firsttime in seven years. Quite apart from wanting to win, Harry foundthat he had fewer nightmares when he was tired out after training. Then, during one particularly wet and muddy practice session,Wood gave the team a bit of bad news. He'd just gotten very angrywith the Weasleys, who kept dive-bombing each other and pretendingto fall off their brooms. "Will you stop messing around!" he yelled. "That's exactlythe sort of thing that'll lose us the match! Snape's refereeingthis time, and he'll be looking for any excuse to knock pointsoff Gryffindor!" George Weasley really did fall off his broom at these words. "Snape's refereeing?" he spluttered through a mouthful ofmud. "When's he ever refereed a Quidditch match? He's not going tobe fair if we might overtake Slytherin." The rest of the team landed next to George to complain, too. "It's not my fault," said Wood. "We've just got to make surewe play a clean game, so Snape hasn't got an excuse to pick on us." Which was all very well, thought Harry, but he had another reasonfor not wanting Snape near him while he was playing Quidditch.... The rest of the team hung back to talk to one another as usualat the end of practice, but Harry headed straight back to theGryffindor common room, where he found Ron and Hermione playingchess. Chess was the only thing Hermione ever lost at, somethingHarry and Ron thought was very good for her. "Don't talk to me for a moment," said Ron when Harry sat downnext to him, "I need to concen --" He caught sight of Harry'sface. "What's the matter with you? You look terrible." Speaking quietly so that no one else would hear, Harry told theother two about Snape's sudden, sinister desire to be a Quidditchreferee. "Don't play," said Hermione at once. "Say you're ill," said Ron. "Pretend to break your leg," Hermione suggested. "Really break your leg," said Ron. "I can't," said Harry. "There isn't a reserve Seeker. If I backout, Gryffindor can't play at all." At that moment Neville toppled into the common room. How hehad managed to climb through the portrait hole was anyone's guess,because his legs had been stuck together with what they recognizedat once as the Leg-Locker Curse. He must have had to bunny hop allthe way up to Gryffindor tower. Everyone fell over laughing except Hermione, who leapt up andperformed the countercurse. Neville's legs sprang apart and hegot to his feet, trembling. "What happened?" Hermione asked him,leading him over to sit with Harry and Ron. "Malfoy," said Neville shakily. "I met him outside thelibrary. He said he'd been looking for someone to practice that on." "Go to Professor McGonagall!" Hermione urged Neville. "Reporthim!" Neville shook his head. "I don't want more trouble," he mumbled. "Y
