In Agatha Christie’s Sleeping Murder, a woman buys a house and then slowly remembers that she lived there as a child . . . when she may have been the sole witness to an unknown murder.
This is a very linear mystery, with lines of investigation raised and dropped one after another. I saw the end result of every line of thinking shortly before the characters did, including the solution. I don’t object to this, but it was notable.
The other thing of note about this story, at least in the radio adaptation, is that Miss Marple has a distinctly supporting role. The point-of-view characters are the woman and her new husband, who Miss Marple advises and does some secondary information gathering for. While the couple aren’t that exceptional, they are nice as a change of pace.
