Second paragraph of third chapter:

‘We’ve planned to take you to a show or two,’ said Raymond whilst Gwenda was drinking gin and rather wishing she could have had a cup of tea after her journey.

I had definitely read this as a teenager: the protagonist, coming to England for the first time (as she thinks) from New Zealand, buys a house with her new husband and immediately starts having flashbacks to witnessing a murder there when a small child. It’s really rather good – totally fair misdirection of the reader, Miss Marple doing her enigmatic yet clear thing, a suitably dramatic and entirely believable revelation at the end. I enjoyed it a lot when I was thirteen and I enjoyed it again now. You can get Sleeping Murder here.

This was actually the last Miss Marple book and indeed the last Agatha Christie novel to be published, coming out a few months after her death in 1976. It’s set during the Second World War, though, and was written between 1940 and 1950 (Christie scholars are divided on exactly when, but the start and end dates are agreed).
