I Shall Wear Midnight

‘There’s a dreadful stink. Even worse than the Feegles.’
    Miss Smith nodded. ‘Yes, it’s coming from his mind. It’s the smell of corruption – corruption of thinking and of action. Your mind picks it up and doesn’t know what to do with it, so it files it under “stink”. All the magically inclined can smell it; but when people encounter it, it changes them, makes them a little bit like him. And so trouble follows wherever he goes.’
    And Tiffany knew exactly what kind of trouble she meant, even though her memories shot her back in time to before the Cunning Man had woken again.
    In her mind’s eye she could see the black-edged pieces blowing back and forth in the late-autumn wind, which sighed with despair in her mind’s ear, and worst of all, oh yes, worst of all, her mind’s nose snuffed up the sharp acrid stink of ancient, half-burned paper. In her memory some of the pieces fluttered in the pitiless wind like moths that had been swatted and broken, but were still hopelessly trying to fly.
    And there were stars on them.
    People had marched to the rough music and roughly dragged out the cracked old woman whose only crime, as far as Tiffany could see, was that she had no teeth left and smelled of wee. They had thrown stones, they had smashed windows, they had killed the cat, and all this had been done by good people, nice people, people that she knew and met every day, and they had done all these things which, even now, they never talked about. It was a day that somehow had vanished from the calendar. And on that day, with a pocketful of charred stars, not knowing what it was she was doing, but determined to do it, she had become a witch.
    ‘You said that others have fought him?’ she said now to Miss Smith. ‘How did they manage it?’
    ‘That last cupcake was still in the bag with the baker’s name on it, I’m sure of it. You’re not sitting on it, are you?’ Miss Smith cleared her throat and said, ‘By being very powerful witches, by understanding what it means to be a powerful witch, and by taking every chance, using every trick and, I suspect, understanding the Cunning Man’s mind before he understands theirs. I have trudged through a long time to learn about the Cunning Man,’ she added, ‘and the one thing I can tell you for certain is that the way to kill the Cunning Man is with cunning. You will need to be more cunning than he is.’
    ‘He can’t be that cunning if he’s taken all this time to find me,’ said Tiffany.
    ‘Yes, that puzzles me,’ said Miss Smith. ‘And it should puzzle you. I would have expected it to have taken him a very long time. More than two years, anyway. He’s either been very clever – and frankly he has nothing to be clever with – or somehow something else has drawn you to his attention. Someone magical, I would guess. Do you know any witches who aren’t your friend?’
    ‘Certainly not,’ said Tiffany. ‘Are any of the witches who have defeated him still alive?’
    ‘Yes.’
    ‘I was wondering, if I found one – perhaps they could tell me how they did it?’
    ‘I’ve told you. He’s the Cunning Man. Why should he fall for the same trick twice? You have to find your own way. Those who have trained you would expect nothing less.’
    ‘This isn’t some kind of test, is it?’ said Tiffany, and then felt embarrassed at how lame that sounded.
    ‘Don’t you remember what Granny Weatherwax always says?’ said Miss Smith.
    ‘ Everything is a test .’ They said it together with one voice, looked at one another and laughed.
    At which point, there was a squawk. Miss Smith opened the door and a small white chicken walked in, looked around curiously and exploded. Where it had been was an onion, fully rigged with mast and sails.
    ‘I’m sorry you had to see that,’ said Miss Smith. She sighed. ‘Happens all the time, I’m afraid. The Unreal Estate is never static, you see. All the magic, banging together, bits of spells winding themselves around other spells, whole new spells being created that nobody has ever thought of before … it’s a mess. It generates things quite randomly. Yesterday I found a book on growing chrysanthemums, printed in copper on water. You would think it would tend to slosh about a bit, but it all seemed to hang together until the magic ran out.’
    ‘That was bad luck for the chicken,’ said Tiffany nervously.
    ‘Well, I can guarantee that it wasn’t a chicken two minutes ago,’ said Miss Smith, ‘and
