'So where were you when it happened, Dad?' asked George.

'That's my business,' said Mr Weasley, though with a small smile. He snatched up the Daily Prophet, shook it open again and said, 'I was just reading about Willy Widdershins's arrest when you arrived. You know Willy turned out to be behind those regurgitating toilets back in the summer? One of his jinxes backfired, the toilet exploded and they found him lying unconscious in the wreckage covered from head to foot in — '

'When you say you were "on duty",' Fred interrupted in a low voice, 'what were you doing?'

'You heard your father,' whispered Mrs Weasley, 'we are not discussing this here! Go on about Willy Widdershins, Arthur.'

'Well, don't ask me how, but he actually got off the toilet charge,' said Mr Weasley grimly. 'I can only suppose gold changed hands — '

'You were guarding it, weren't you?' said George quietly. 'The weapon? The thing You-Know-Who's after?'

'George, be quiet!' snapped Mrs Weasley.

'Anyway,' said Mr Weasley, in a raised voice, 'this time Willy's been caught selling biting doorknobs to Muggles and I don't think he'll be able to worm his way out of it because, according to this article, two Muggles have lost fingers and are now in St Mungo's for emergency bone re-growth and memory modification. Just think of it, Muggles in St Mungo's! I wonder which ward they're in?'

And he looked eagerly around as though hoping to see a signpost.

'Didn't you say You-Know-Who's got a snake, Harry?' asked Fred, looking at his father for a reaction. 'A massive one? You saw it the night he returned, didn't you?'

'That's enough,' said Mrs Weasley crossly. 'Mad-Eye and Tonks are outside, Arthur, they want to come and see you. And you lot can wait outside,' she added to her children and Harry. 'You can come and say goodbye afterwards. Go on.'

They trooped back into the corridor. Mad-Eye and Tonks went in and closed the door of the ward behind them. Fred raised his eyebrows.

'Fine,' he said coolly, rummaging in his pockets, 'be like that. Don't tell us anything.'

'Looking for these?' said George, holding out what looked like a tangle of flesh-coloured string.

'You read my mind,' said Fred, grinning. 'Let's see if St Mungo's puts Imperturbable Charms on its ward doors, shall we?'

He and George disentangled the string and separated five Extendable Ears from each other. Fred and George handed them around. Harry hesitated to take one.

'Go on, Harry, take it! You saved Dad's life. If anyone's got the right to eavesdrop on him, it's you.'

Grinning in spite of himself, Harry took the end of the string and inserted it into his ear as the twins had done.

'OK, go!' Fred whispered.

The flesh-coloured strings wriggled like long skinny worms and snaked under the door. At first, Harry could hear nothing, then he jumped as he heard Tonks whispering as clearly as though she were standing right beside him.

'. . . they searched the whole area but couldn't find the snake anywhere. It just seems to have vanished after it attacked you, Arthur . . . but You-Know-Who can't have expected a snake to get in, can he?'

'I reckon he sent it as a lookout,' growled Moody, ' 'cause he's not had any luck so far, has he? No, I reckon he's trying to get a clearer picture of what he's facing and if Arthur hadn't been there the beast would've had a lot more time to look around. So, Potter says he saw it all happen?'

'Yes,' said Mrs Weasley. She sounded rather uneasy. 'You know, Dumbledore seems almost to have been waiting for Harry to see something like this.'

'Yeah, well,' said Moody, 'there's something funny about the Potter kid, we all know that.'

'Dumbledore seemed worried about Harry when I spoke to him this morning,' whispered Mrs Weasley.

' 'Course he's worried,' growled Moody. 'The boy's seeing things from inside You-Know-Who's snake. Obviously, Potter doesn't realise what that means, but if You-Know-Who's possessing him — '

Harry pulled the Extendable Ear out of his own, his heart hammering very fast and heat rushing up his face. He looked around at the others. They were all staring at him, the strings still trailing from their ears, looking suddenly fearful.
