From Chapter 23

Deputy Minister Dolores Umbridge was furious. She hurled five of her finest china plates with pictures of pink cats on them against the pink pin-striped wall of her office, shattering them all over her pink cushions and her pink shag carpet. Ministry staffers passing by ignored the sounds of outrage coming from her office. They were used to it, and they were thankful that Dolores didn't have any real power.

Deputy Minister Umbridge turned back and glared at the files on her desk. Black, Potter, Granger, Dumbledore, and McGonagall. She added Cornelius Fudge's file to the grouping. She had known he was soft on Potter and overly reliant on Dumbledore. That was his weak point. Dolores had been working on Cornelius ever since she had heard that James Potter's son was attending Hogwarts. But apparently Dumbledore had beaten her to Fudge's soul.

Dolores decided then and there that it was time for a New Order in the wizard world - a Pureblood order under her thumb. She would eliminate the mudbloods and the half-breeds once and for all. If Voldemort was after the Ministry, and actually managed to return from the dead, he would have to fight her for it.

Hermione was confused. On the one hand, she could sense straightaway that Professor Lupin and Mr Black's intentions were good, but they didn't smell right and the fur on her spine and tail stood on end. Mr Black had a distinct canine odour mixed with his human scent. Professor Lupin had a canine/human whiff too, but his was somehow different - wilder.

Anxiously, Hermione tightened her grip on Harry's arm when Sirius Black rose to greet Harry, and she instinctively hissed. Harry and Sirius both stopped. Sirius looked crestfallen. Hermione was appalled with herself and tears filled her eyes.

"I'm so sorry Mr Black... Harry! I don't know what's wrong with me. Something just came over me."

"I know what's wrong," said Professor Lupin quietly. "Miss Granger, Sirius Black is an Animagus - a skin changer. His animal form is that of a dog. And me... I'm a werewolf."
