My rating: 3 of 5 stars
What one might expect from Terry Pratchett: whacky humour, intimately realized world, twists, turns and nefarious deeds. In short, another installment of escapism at its best.
In this Discworld edition, Pratchett returns to our stalwart policing crew, The Watch, who become embroiled in a series of dastardly murders, the question of what makes a thing a thing with rights, or just a machine, and the examination of class structure. All of this told with intelligence and aplomb.
