Book review: the Mystery of the Blue Train

Another Christie. Not too bad, though (for me) rather broken up; I read it over about a month with gaps; so I was even less than usually encouraged to guess the solution. Another with "Americans" as the source of money and hence action; the Europeans are predators mostly. The driver of the story, fabulous rubies and a divorce, seems rather dull now.

Quibbles: that Ava Mason should be a male impersonator seems an over-clue. She doesn't need to be. She just walks off the train dressed as a man, FFS, she could do that just as any old female actor. I also feel that the two-unreliable-narrators means that a lot of the story / description - who was the man on the train? - is effectively nulled out, which is dissatisfying. Had I been paying more attention, I'd have felt cheated.
