Snuff - Terry Pratchett

This is the countryside, after all. Everyone sees where you go and you never know who is behind a hedge.

And if you're very unlucky, the person behind the hedge could have very unfriendly intentions. It may look idyllic, but the countryside isn't all flowers and thatched cottages and bracing walks in your best tweed. Beneath the greenery lies a dark underbelly, and there's something about rambling country houses that attracts dastardly plots and grisly murder. A challenge for any detective, but especially for one bred in the city who doesn't understand the Way Things Are Done. In the countryside, people know their place, and everyone else's place too, especially if it's beneath their own.
And they have some rather old fashioned ideas about people who are.different from them.
