This wolf was trying to be human.
There was probably no cure.
'Here's your milk,' said Nanny Ogg.
Granny reached up and took it without looking.
'Someone made this wolf think it was a person,' she said. 'They made it think it was a person and then they didn't think any more about it. It happened a few years ago.'
'How do you know?'
'I've . . . got its memories,' said Granny. And instincts, too, she thought. She knew it'd be some days before she'd stop wanting to chase sledges over the snow.
'Oh.'
'It's stuck between species. In its head.'
'Can we help it?' said Nanny.
Granny shook her head.
'It's gone on for too long. It's habit now. And it's starving. It can't go one way, it can't go t'other. It can't act like a wolf, and it can't manage being a human. And it can't go on like it is.'
She turned to face Nanny for the first time. Nanny took a step back.
'You can't imagine how it feels,' she said. 'Wandering around for years. Not capable of acting human, and not able to be a wolf. You can't imagine how that feels.'
'I reckon maybe I can,' said Nanny. 'In your face. Maybe I can. Who'd do that to a creature?'
'I've got my suspicions.'
They looked around.
Magrat was approaching, with the child. Beside them walked one of the woodcutters.
'Hah,' said Granny. 'Yes. Of course. There's always got to be' - she spat the words - 'a happy ending.''
A paw tried to grip her ankle.
Granny Weatherwax looked down into the wolf's face.
'Preeees,' it growled. 'Annn enndinggg? Noaaaow?'
She knelt down, and took the paw.
'Yes?' she said.
'Yessss!'
She stood up again, all authority, and beckoned to the approaching trio.
'Mr Woodcutter?' she said. 'A job for you . . .'
The woodcutter never understood why the wolf laid its head on the stump so readily.
Or why the old woman, the one in whom anger roiled like pearl barley in a bubbling stew, insisted afterwards that it be buried properly instead of skinned and thrown in the bushes. She had been very insistent about that.
And that was the end of the big bad wolf.
