At six o’clock every night, without fail, Commander Sam Vimes of the City Watch must go home to read Where’s My Cow?, with all the right farmyard animal noises, to his little boy. It is the only thing that keeps him sane in an increasingly insane world. But, Sam wonders, why is this book full of moo-cows and baa-lambs when Young Sam will only ever see them cooked on a plate? He can’t help but feel there should be a more useful book for a boy who lives in a big city. So Sam starts adapting the story. A story with dark streets, not sunny fields. A book with rogues and criminals. A tale about the place where he’ll grow up—a city that his father must protect every day.

Illustrated with four-color art by artist Melvyn Grant, Where’s My Cow? is an engagingly clever story-within-a-story that will appeal to all Pratchett fans.
