ted to the Selwynsa133。 Indeed； there are few pure…blood families to whom I am not related。 a133A pity；〃 she continued in a louder voice； flicking through Mrs。 Cattermole's questionnaire； 〃that the same cannot be said for you。 'iParents professions： greengrocersi'。〃
Yaxley laughed jeeringly。 Below； the fluffy silver cat patrolled up and down； and the dementors stood waiting in the corners。
It was Umbridge's lie that brought the blood surging into Harry's brain and obliterated his sense of caution … that the locket she had taken as a bribe from a petty criminal was being used to bolster her own pure…blood credentials。 He raised his wand； not even troubling to keep it concealed beneath the Invisibility Cloak； and said； 〃iStupefy！i〃
There was a flash of red light； Umbridge crumpled and her forehead hit the edge of the balustrade： Mrs。 Cattermole's papers slid off her lap onto the floor and； down below； the prowling silver cat vanished。 Ice…cold air hit them like an oning wind： Yaxley； confused； looked around for the source of the trouble and saw Harry's disembodied hand and wand pointing at him。 He tried to draw his own wand； but too late： 〃iStupefy！i〃
Yaxley slid to the ground to lie curled on the floor。
〃Harry！〃
〃Hermione； if you think I was going to sit here and let her pretend …〃
〃Harry； Mrs。 Cattermole！〃
Harry whirled around； throwing off the Invisibility Cloak； down below； the dementors had moved out of their corners； they were gliding toward the woman chained to the chair： Whether because the Patronus had vanished or because they sensed that their masters were no longer in control； they seemed to have abandoned restraint。 Mrs。 Cattermole let out a terrible scream of fear as a slimy； scabbed hand grasped her chin and forced her face back。
〃iEXPECTO PATRONUM！i〃
The silver stag soared from the tip of Harry's wand and leaped toward the dementors； which fell back and melted into the dark shadows again。 The stag's light； more powerful and more warming than the cat's protection； filled the whole dungeon as it cantered around the room。
〃Get the Horcrux；〃 Harry told Hermione。
He ran back down the steps； stuffing the Invisibility Cloak into his back； and approached Mrs。 Cattermole。
〃You？〃 she whispered； gazing into his face。 〃But … but Reg said you were the one who submitted my name for questioning！〃
〃Did I？〃 muttered Harry； tugging at the chains binding her arms； 〃Well； I've had a change of heart。 iDiffindo！i〃 Nothing happened。 〃Hermione； how do I get rid of these chains？〃 〃Wait； I'm trying something up here …〃
〃Hermione； we're surrounded by dementors！〃
〃I know that； Harry； but if she wakes up and the locket's gone … I need to duplicate it … iGeminio！i Therea133 That should fool hera133。〃
Hermione came running downstairs。
〃Let's seea133。 iRelashio！i〃
The chains clinked and withdrew into the arms of the chair。 Mrs。 Cattermole looked just as frightened as ever before。
〃I don't understand；〃 she whispered。
〃You're going to leave here with us；〃 said Harry； pulling her to her feet。 〃Go home； grab your children； and get out； get out of the country if you've got to。 Disguise yourselves and run。 You've seen how it is； you won't get anything like a fair hearing here。〃
〃Harry；〃 said Hermione； 〃how are we going to get out of here with all those dementors outside the door？〃
〃Patronuses；〃 said Harry； pointing his wand at his own。 The stag slowed and walked； still gleaming brightly； toward the door。 〃As many as we can muster； do yours； Hermione。〃
〃iExpec … Expecto patronum；i〃 said Hermione。 Nothing happened。
〃It's the only spell she ever has trouble with；〃 Harry told a pletely bemused Mrs。 Cattermole。 〃Bit unfortunate； reallya133 e on Hermionea133。〃
'iExpecto patronum！i〃
A silver otter burst from the end of Hermione's wand and swam gracefully through the air to join the stag。
〃C'mon；〃 said Harry； and he led Hermione and Mrs。 Cattermole to the door。
When the Patronuses glided out of the dungeon there were cries of shock from the people waiting outside。 Harry looked around； the dementors were falling back on both sides of them； melding into the darkness； scattering before the silver creatures。
〃It's been decided that you should all go home and go into hiding with your families；〃 Harry told the waiting Muggle…born； who were dazzled by the light of the Patronuses and still cowering slightly。 〃Go abroad if you can。 Just get well away from the Ministry。 That's the … er … new official position。 Now； if you'll just follow the Patronuses； you'll be able to leave the Atrium。〃
They managed to get up the stone stops without being intercepted； but as they approached the lifts Harry started to have misgivings。 If they emerged into the Atrium with a silver stag； and otter soaring alongside it； and twenty or so people； half of them accused Muggle…borns； he could not help feeling that they would attract unwanted attention。 He had just reached this unwele conclusion when the lift clanged to a halt in front of them。
〃Reg！〃 screamed Mrs。 Cattermole； and she threw herself into Ron's arms。 〃Runcorn let me out； he attacked Umbridge and Yaxley； and he's told all of us to leave the country。 I think we'd better do it； Reg； I really do； let's hurry home and fetch the children and … why are you so wet？〃
〃Water；〃 muttered Ron； disengaging himself。 〃Harry； they know there are intruders inside the Ministry； something about a hole in Umbridge's office door。 I reckon we've got five minutes if that …〃
Hermione's Patronus vanished with a ipopi as she turned a horror struck face to Harry。
〃Harry； if we're trapped here … ！〃
〃We won't be if we move fast；〃 said Harry。 He addressed the silent group behind them； who were all gawping at him。
〃Who's got wands？〃
About half of them raised their hands。
〃Okay； all of you who haven't got wands need to attach yourself to somebody who has。 We'll need to be fast before they stop us。 e on。〃
They managed to cram themselves into two lifts。 Harry's Patronus stood sentinel before the golden grilles as they shut and the lifts began to rise。
〃Level eight；〃 said the witch's cool voice； 〃Atrium。〃
Harry knew at once that they were in trouble。 The Atrium was full of people moving from fireplace to fireplace； sealing them off。
〃Harry！〃 squeaked Hermione。 〃What are we going to … ？〃
〃STOP！〃 Harry thundered； and the powerful voice of Runcorn echoed through the Atrium： The wizards sealing the fireplaces froze。 〃Follow me；〃 he whispered to the group of terrified Muggle…borns； who moved forward in a huddle； shepherded by Ron and Hermione。
〃What's up； Albert？〃 said the same balding wizard who had followed Harry out of the fireplace earlier。 He looked nervous。
〃This lot need to leave before you seal the exits；〃 said Harry with all the authority he could muster。
The group of wizards in front of him looked at one another。
〃We've been told to seal all exits and not let anyone …〃
〃iAre you contradicting me？i〃 Harry blustered。 〃Would you like me to have your family tree examined； like I had Dirk Cresswell's？〃
〃Sorry！〃 gasped the balding wizard； backing away。 〃I didn't mean nothing； Albert； but I thoughta133 I thought they were in for questioning anda133〃
〃Their blood is pure；〃 said Harry； and h
