Wyrd Sisters (Discworld 6)

'It looked pretty convincing to me.'

'Of course it did, it was meant—' the duchess began.

She sighed, and snatched a spear out of the guard's hand.

'I'll show you the power of these witches,' she said, and hurled it at Granny's face.

Granny moved her hand across at snakebite speed and caught the spear just behind the head.

'So,' she said, 'and it comes to this, does it?'

'You don't frighten me, wyrd sisters,' said the duchess.

Granny stared her in the eye for a few seconds. She gave a grunt of surprise.

'You're right,' she said. 'We really don't, do we . . .'

'Do you think I haven't studied you? Your witchcraft is all artifice and illusion, to amaze weak minds. It holds no fears for me. Do your worst.'

Granny studied her for a while.

'My worst?' she said, eventually. Magrat and Nanny Ogg shuffled gently out of her way.

The duchess laughed.

'You're clever,' she said. 'I'll grant you that much. And quick. Come on, hag. Bring on your toads and demons, I'll . . .'

She stopped, her mouth opening and shutting a bit without any words emerging. Her lips drew back in a rictus of terror, her eyes looked beyond Granny, beyond the world, towards something else. One knuckled hand flew to her mouth and she made a little whimpering noise. She froze, like a rabbit that has just seen a stoat and knows, without any doubt, that it is the last stoat that it will ever see.

'What have you done to her?' said Magrat, the first to dare to speak. Granny smirked.

'Headology,' said Granny, and smirked. 'You don't need any Black Aliss magic for it.'

'Yes, but what have you done?'

'No-one becomes like she is without building walls inside their head,' she said. Tve just knocked them down. Every scream. Every plea. Every pang of guilt. Every twinge of conscience. All at once. There's a little trick to it.'

She gave Magrat a condescending smile. 'I'll show you one day, if you like.'

Magrat thought about it. 'It's horrible,' she said.

'Nonsense,' Granny smiled terribly. 'Everyone wants to know their true self. Now, she does.'

'Sometimes you have to be kind to be cruel,' said Nanny Ogg approvingly.

'I think it's probably the worst thing that could happen to anyone,' said Magrat, as the duchess swayed backwards and forwards.

'For goodness' sake use your imagination, girl,' said Granny. 'There are far worse things. Needles under the fingernails, for one. Stuff with pliers.'

'Red-hot knives up the jacksie,' said Nanny Ogg. 'Handle first, too, so you cut your fingers trying to pull them out—'

'This is simply the worst that I can do,' said Granny Weatherwax primly. 'It's all right and proper, too. A witch should act like that, you know. There's no need for any dramatic stuff. Most magic goes on in the head. It's headology. Now, if you'd—'

A noise like a gas leak escaped from the duchess's lips. Her head jerked back suddenly. She opened her eyes, blinked, and focused on Granny. Sheer hatred suffused her features.

'Guards!' she said. 'I told you to take them!'

Granny's jaw sagged. 'What?' she said. 'But – but I showed you your true self . . .'
