Snuff is a Vimes novel. Reviewerly protocol demands that I not give away any of its contents in detail, so I'll just say that it features the countryside, Jane Austen, slavery, river boats, snot, tobacco and a lot of fisticuffs. It also features a Vimes who, for the first time, feels as if he has acquired more indestructibility, more elaborated superlative Vimes-ish-ness, than can be kept in harmoniously plausible balance with his setting.
