More out of habit than anything, Harry made his usual detour along the seventh-floor corridor, checking the Marauder's Map as he went. For a moment he could not find Malfoy anywhere,and assumed he must indeed be inside the Room of Requirement again, but then he saw Malfoy's tiny, labelled dot standing in a boys' bathroom on the floor below, accompanied, not by Crabbe or Goyle but by Moaning Myrtle.Harry only stopped staring at this unlikelycoupling when he walked right into a suit of armour. The loud crash brought him out of his reverie; hurrying from the scene lest Filch should turn up, he dashed down the marble staircase and along the passageway below. Outside the bathroom, he pressed his ear against the door.He couldn't hear anything. He very quietly pushed the door open.Draco Malfoy was standing with his back to the door, his hands clutching either side of the sink, his white-blond head bowed."Don't."crooned Moaning Myrtle's voice from one of the cubicles."Don't...tell me what's wrong...I can help you...""No one can help me."said Malfoy. His whole body was shaking."I can't do it...I can't...it won't work...and unless I do it soon, he says he'll kill me..."And Harry realised, with a shock so huge it seemed to root him to the spot,that Malfoy was crying- actually crying- tears streaming down his pale face into the grimy basin. Malfoy gasped and gulped and then, with a great shudder, looked up into the cracked mirror and saw Harry staring at him over his shoulder.Malfoy wheeled round, drawing his wand. Instinctively, Harry pulled out his own. Malfoy's hex missed Harry by inches, shattering the lamp on the wall beside him; Harry threw himself sideways, thought Levicorpus! and flicked his wand but Malfoy blocked the jinx and raised his wand for another."No! No! Stop it!"squealed Moaning Myrtle, her voice echoing loudly around the tiled room."Stop! Stop!"There was a loud band and the bin behind Harry exploded, Harry attemped a Leg-Locker Curs that backfired off the wall behind Malfoy's ear and smashed the cistern beneath Moaning Myrtle, who screamed loudly; water poured everywhere and Harry slipped over and Malfoy, his face contorted, cried,"Cruci-""SECTUMSEMPRA!" bellowed Harry from the floor,waving his wand wildly.Blood spured from Malfoy's face and chest as though he had been slashed with an invisiablesword. He staggered backwards and collaspsed on to the waterlogged floor with a great splash, his wand falling from his limp right hand.——选自《Harry Potter and the Half-Blood Prince》英国原版第24章《Sectumsempra》
