The Murder at the Vicarage
While Miss Marple is described as "an old lady" in many of the stories, her age is mentioned in "At Bertram's Hotel", where it is said she visited the hotel when she was fourteen and almost sixty years have passed since then. Excluding "Sleeping Murder", forty-one years passed between the first and last-written novels, and many characters grow and age. An example would be the Vicar's nephew: in "The Murder at the Vicarage", the Reverend Mr Clement's nephew Dennis is a teenager; in "The Mirror Crack'd from Side to Side", it is mentioned that the nephew is now grown and successful and has a career. The effects of ageing are seen on Miss Marple, such as needing a holiday after illness in "A Caribbean Mystery" but she is if anything more agile in "Nemesis", set only sixteen months later.
