I'm not sure how it happened that I have never read Three Act Tragedy (sometimes known as Murder in Three Acts). I had assumed that this would be a re-read. But as I really did not remember the plot, I guess that this was either the first time that I have read it, or I read it so long ago as to no longer register.
As Poirots go, this is considered a minor example. The moustached detective plays a relatively small part, and the characters are perhaps not quite as strong as in other Christie classics.
There are still many interesting aspects to the novel. Christie's use of misdirection is masterful, and she actually allows us to dislike a number of her choices until everything becomes clear at the end. She seems to be saying some smart things about relationships, and Egg is a good example of the Christie female hero.
I read it while on vacation, and can heartily recommend that you do the same.
