Koom Valley? That was where the trolls ambushed the dwarves, or the dwarves ambushed the trolls. It was far away. It 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 if 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.
