I never thought I'd give an Agatha Christie 2 stars...

It started off well but just got more and more drawn out/boring as it went, and the big reveal was soo random that you'd never have been able to guess it. Totally unsatisfying.

I did listen to it as an audiobook (which I've never done before) so maybe that's why I felt so out of touch with the story? But still, it definitely isn't her best work.
