In Thief of Time in the great stinking metropolis of Ankh Morpork, an obsessed clockmaker receives an unusual commission from an excessively beautiful woman whose feet do not touch the ground; strict school-teacher Susan finds herself summoned by her grandfather, Death, to do him a favour; the monks who manage the even distribution of Time find themselves with a recalcitrant novice; and dairyman Ronnie Soak muses on his glory days, when he was the Fifth Rider of the Apocalypse, the one who left before they got famous.
