Hercule Poirot must solve a murder, but before that, he must find out if a murder has even been committed, & before that, he must find the girl who came to him & confessed to a potential murder. He doesn't know her name or where she lives, so he must really start from scratch, making the mystery unfold a bit slowly.

Poirot is not my favorite of Agatha Christie's novels, but I did enjoy this one a lot. It was fun seeing him have to figure out so many new things. Also, the story was published in 1966. Poirot is now an old man, struggling to comprehend the changes in society, such as how women dress & act & what kind of men they are attracted to. Poirot knows he's a bit of a fuddy-duddy, but can't help yearning for an earlier time.

Ariadne Oliver joins Poirot as well. I've never read the Oliver books, & I think I'll enjoy them. Ms. Oliver was funny, & a bit exasperating for Poirot.

As usual, I didn't guess the killer or the motive correctly, & the twist at the end was a big one, & I didn't see it coming. Agatha Christie is still one of the greatest writers, & greatest crime fiction writers, of all time, precisely because of her twists & red herrings that keep you guessing until the last page.
