Harry Potter and the Goblet of Fire
"So they're dead?" said Harry quietly.
"No," said Dumbledore, his voice full of a bitterness Harry had never heard there before. "They are insane. They are both in St. Mungo's Hospital for Magical Maladies and Injuries. I believe Neville visits them, with his grandmother, during the holidays. They do not recognize him."
Harry sat there, horror-struck. He had never known ... never, in four years, bothered to find out ...
"The Longbottoms were very popular," said Dumbledore. "The attacks on them came after Voldemort's fall from power, just when everyone thought they were safe. Those attacks caused a wave of fury such as I have never known. The Ministry was under great pressure to catch those who had done it. Unfortunately, the Longbottoms' evidence was – given their condition – none too reliable." (30.187-90)
"Ignore him," said Cedric in a low voice to Harry, frowning after his father. "He's been angry ever since Rita Skeeter's article about the Triwizard Tournament – you know, when she made out you were the only Hogwarts champion."
"Didn't bother to correct her, though, did he?" said Amos Diggory, loudly enough for Harry to hear as he started to walk out of the door with Mrs. Weasley and Bill. "Still ... you'll show him, Ced. Beaten him once before, haven't you?"
"Rita Skeeter goes out of her way to cause trouble, Amos!" Mrs. Weasley said angrily. "I would have thought you'd know that, working at the Ministry!" (31.92-4)
Wormtail's robes were shining with blood, now; he had wrapped the stump of his arm in them.
"My Lord ..." he choked. "My Lord ... you promised ... you did promise ..."
"Hold out your arm," said Voldemort lazily.
"Oh Master ... thank you, Master ..."
He extended the bleeding stump, but Voldemort laughed again.
"The other arm, Wormtail."
"Master, please ... please ..."
Voldemort bent down and pulled out Wormtail's left arm; he forced the sleeve of Wormtail's robes up past his elbow, and Harry saw something upon the skin there, something like a vivid red tattoo – a skull with a snake protruding from its mouth – the image that had appeared in the sky at the Quidditch World Cup: the Dark Mark. Voldemort examined it carefully, ignoring Wormtail's uncontrollable weeping. (33.2-9)
