Instinctively, Harry looked at Dumbledore, who smiled faintly, the firelight glancing off his half moon spectacles.
“What interests me most,” said Dumbledore gently, “is how Lord Voldemort managed to enchant Ginny, when my sources tell me he is currently in hiding in the forests of Albania.”
Relief—warm, sweeping, glorious relief—swept over Harry. “W-what’s that?” said Mr. Weasley in a stunned voice. “You-Know-Who? En-enchant Ginny? But Ginny’s not… Ginny hasn’t been… has she?”
“It was this diary,” said Harry quickly, picking it up and showing it to Dumbledore. “Riddle wrote it when he was sixteen…”
Dumbledore took the diary from Harry and peered keenly down his long, crooked nose at its burnt and soggy pages.
“Brilliant,” he said softly. “Of course, he was probably the most brilliant student Hogwarts has ever seen.” He turned around to the Weasleys, who were looking utterly bewildered.
“Very few people know that Lord Voldemort was once called Tom Riddle. I taught him myself, fifty years ago, at Hogwarts. He disappeared after leaving the school… traveled far and wide… sank so deeply into the Dark Arts, consorted with the very worst of our kind, underwent so many dangerous, magical transformations, that when he resurfaced as Lord Voldemort, he was barely recognizable. Hardly anyone connected Lord Voldemort with the clever, handsome boy who was once Head Boy here.”
“But, Ginny,” said Mrs. Weasley. “What’s our Ginny got to do with—with—him?”
“His d-diary!” Ginny sobbed. “I’ve b-been writing in it, and he’s been w-writing back all year—”
“Ginny!” said Mr. Weasley, flabbergasted. “Haven’t I taught you anything? What have I always told you? Never trust anything that can think for itself if you can’t see where it keeps its brain? Why didn’t you show the diary to me, or your mother? A suspicious object like that, it was clearly full of Dark Magic!”
“I d-didn’t know,” sobbed Ginny. “I found it inside one of the books Mum got me. I th-thought someone had just left it in there and forgotten about it—”
“Miss Weasley should go up to the hospital wing right away,” Dumbledore interrupted in a firm voice. “This has been a terrible ordeal for her. There will be no punishment. Older and wiser wizards than she have been hoodwinked by Lord Voldemort.” He strode over to the door and opened it. “Bed rest and perhaps a large, steaming mug of hot chocolate. I always find that cheers me up,” he added, twinkling kindly down at her. “You will find that Madam Pomfrey is still awake. She’s just giving out Mandrake juice—I daresay the basilisk’s victims will be waking up any moment.”
“So Hermione’s okay!” said Ron brightly.
“There has been no lasting harm done, Ginny,” said Dumbledore.
