The Murder at the Vicarage
Miss Marple's St Mary Mead is described in "The Murder at the Vicarage" as being in the fictional county of Downshire, but in the later novel "The Body in the Library" Downshire has become Radfordshire. In the BBC Miss Marple TV adaptation of "Nemesis", a letter from Mr Rafiel's solicitors indicate that St Mary Mead is located in the (also fictional) county of Middleshire. The St Mary Mead of Katherine Grey is in Kent.
