Terry Pratchett: Wyrd Sisters
Corgi Books 1989 (1988)
‘You know, Hwel, I reckon responsible behaviour is something to get when you grow older. Like varicose veins.’
— Tomjon in ‘Wyrd Sisters’
The fourth in Pratchett’s Discworld series is full of witches behaving badly, meddling yet not meddling in the affairs of men. Preceded by Equal Rites it focuses on the kingdom of Lancre with its usurping ruler Duke Felmet and his wife, a castle full of ghosts, a troupe of travelling players and the aforementioned witch trio of Esme Weatherwax, Gytha Ogg and Magrat Garlick.
It’s not the assassination itself that sets things awry — Lancre has seen dastardly deeds done to royalty before and survived — but the misrule following it, and Granny Weatherwax senses the land is unhappy. For this reason and others (such as her being a dyed-in-the-wool contrarian) she determines, along with her coven of three, to nudge things along a bit.
And that includes a bit of messing around with time, accomplished in a manner similar to the ending of Superman the Movie, except with a black-caped Granny flying her broomstick round the kingdom.
