The Discworld: a topsy-turvy world, spinning lazily through space on four huge elephants standing on the back of the star-turtle Great A'Tuin. A magical world: no more so than in Lancre, a tiny kingdom close to the very hub of the disc. But evil is afoot in Lancre: King Verence has been brutally murdered by Duke Felmet, who has assumed the throne; yet all is not lost - Verence's baby son has been carried off and given into the care of three witches. Can the Wyrd Sisters oust Duke Felmet and restore the true king to the throne? Or will Lady Felmet get away with her programme of hygienic urban clearance and environmental improvements?
