Well, this one has surprised me. There's so much humour in it and yet there's also more violence and a deeper sense of threat than I'm used to.
I love the opening when a girl looking for help comes to Poirot and then leaves because he's too old to help her, which, of course, guarantees his involvement.
Adriadne Oliver is a hoot when she plays detective.
I've no real clue where this is going but do like how it's getting there.
