Some people would be asking: whose side are you on? If you're not for us,
you're against us. Huh. If you're not an apple, you're a banana'. Koom Valley,
the ancient battle where the trolls ambushed the dwarfs, or the dwarfs ambushed
the trolls, was a long time ago. But if he doesn't solve the murder of just one
dwarf, Commander Sam Vimes of Ankh-Morpork City Watch is going to see it fought
again, right outside his office. With his beloved Watch crumbling around him and
war-drums sounding, he must unravel every clue, outwit every assassin and brave
any darkness to find the solution. And darkness is following him. Oh . . . and
at six o'clock every day, without fail, with no excuses, he must go home to read
'Where's My Cow?', with all the right farmyard noises, to his little boy. There
are some things you have to do.
