Well I thought I'd long since read all the Hercule Poirot mysteries, so it was a positive shock to find this novel in a second-hand bookshop, which I don't remember ever seeing before. When I read it, I still wasn't sure. Have I read this some twenty or thirty years ago and just forgotten it? Or are my vague stirrings of memory just being jogged because all the Christie novels were similar in style and plot.

I actually managed to solve part of this one, which is reassuring as it shows my brain hasn't yet atrophied. Also, I spotted what I think is a hole in the plot... or rather, an unnecessary complication. Of course, it doesn't matter in the slightest. I always enjoy reading about Hercule Poirot and his little grey cells, and I enjoyed Death in the Clouds as much as any other.
