I´m afraid, this will never be one of my favorite Poirot novels.
The mystery is good and pretty dark, actually, and I like that you can tell that Poirot is old and kind of weary. This book gave me a bit of a nostalgic feeling while reading it.
The constant youth bashing in this book was really grating on my nerves, though. So overall, this was merely an ok read for me.
"He very much regrets that he will not be able to join you this evening. He is in bed with a serious bout of `flu."
"He has not got `flu," said Hercule Poirot. "He has only a nasty cold. [...]"
LoL. That´s exactly what I´m telling my customers whenever they say that they got the flu. If they would have the flu, they wouldn´t be able to stand in front of me. So stop saying that!
Gosh, I love Poirot so much right now.
