"It's only words, and words are all I have, to take your heart away." —Bee Gees
"It is so mad, my friend, that sometimes I am haunted by the sensation that really it must be very simple."
In anticipation of the movie I went to check if I had read this, and it turned out I hadn't. I didn't know what I'd been missing. To echo Poirot: Mon Dieu! What a fun mystery. The plot is so simple; a locked room murder is discovered, evidence are gathered, all the suspects are interviewed. Certainly there are some weak points, like a few improbable guesses and a resolution that wraps up things too neatly, but it's still an enjoyable book which has a deliciously clever ending which I could not have predicted, though I did catch some of the clues. After finishing I went straight back for a quick reread with my new knowledge of the ending. I predict this will join And Then There Were None and Curtain in my list of Christie books with the most memorable endings that stick with me for a long time.
