Some night-time prowler is turning the (mostly) honest citizens of Ankh-Morpork into something resembling small charcoal biscuits. And that's a real problem for Captain Vimes, who must tramp the mean streets of the naked city looking for a seventy-foot-long fire-breathing dragon which, he believes, can help him with his enquiries. But there's more - now we get to see Ankh-Morpork in all its glory; illustrations so vibrant you can practically smell and taste the denizens of this delightful city (although with Corporal Nobbs, you might rather wish you didn't have to). All rendered in painstaking detail by Graham Higgins (who feels he now knows altogether far too much about the murky goings on inside Nobbs' head).
