A quick, enjoyable mystery, though I do think it's a little laboured in some places. The solution of the mystery, at the end of the book, describes a sequence of events that is very convoluted, and which I frankly did not much credit, but I was engaged in the story up until that point, so the last few pages didn't spoil it entirely. I was surprised to find, however, that Miss Marple is really only a supporting character here. She solves the mystery, of course, but for a lot of the book she's entirely in the background. I've only read one other of the Miss Marple books, and that was a year or two back so I don't entirely remember the level of focus placed upon her, but I've read rather more of the Poirot books and he always seems much more centre stage. Oh well. It didn't affect my enjoyment - the story still zipped along very quickly - but I hope, when I get around to reading other books in this series, that Miss Marple gets a bit more attention, because I enjoy her absolute cynicism about the world... genteel as the expression of that cynicism may be.
