Labours of Hercules

The Labours Of Hercules
by Agatha Christie
My rating: 4 of 5 stars

I wasn't sure I would like this as I'm not a huge fan of short stories, but these were interconnected enough that the book was a coherent whole.
The stories are of Poirot's (presumably) last 12 cases which he decides he will choose to fit the pattern of the classical labors of Hercules. These are mostly cases of missing items or people, and several have clever twists to them.
There is a funny bit in the Cerberus story where Poirot is in the London tube and he is not pleased, among other things he comments on women knitting in the tube.
