Agatha Christie designed the modern mystery- many of the tropes we see in the genre today are inspired by her works. Based on these tropes, I enjoy predicting the ending of Hercule Poirot novels as he himself is solving the mystery. I was about 50% right on this one. 
The plot is easy to follow and the dialogue enjoyable and lighthearted, save for several outdated notions regarding nationality and gender. Discussions of class or occupation are to be expected in a story from the 1930s, but a reader who will do more than roll their eyes at other prejudiced comments is not likely to enjoy this story. 
Nothing will Murder on the Orient Express for me, that was one of the first non-YA novels to really grab my attention and fully immerse me. But this story is innovative and modern for its time. I especially enjoyed the frequent character interactions and side plots, as opposed to Poirot making ceaseless investigations while being followed around by some wide-eyed admirer. Regardless, I enjoy his arrogance in this one; Poirot was given a very human depth amidst his usual suspicious meddling. 

I think this is the funniest Agatha Christie's book I've ever read. By that I mean it has a lot more jokes than usual! Christie was witty and sometimes there are jokes here and there that work in the books, but this by far has a lot and I was actually laughing when I found them (the jokes).

Okay. Now the plot. I think it's fine, the idea was actually pretty convoluted but it was executed in perfect pace to make the readers (me) understand. It actually didn't feel far-fetched.

because....men.

This book was also fun especially if you read it in one sitting, because you go on adventure going from one character to another. Yes there are a lot of characters, and it was pretty confusing at first especially when they're all on the plane (the first few chapters) but after that Ms Christie made sure that they're all distinct.

For the twist, believe it or not I predicted it. I actually underlined a sentence where I had that feeling " this person did it" because I've read so much of these books that I think when I read it I can see the pattern and got the vibe of what the author wants me to think about this character. But there are several twists in this book and at first it seemed like the conclusion came out of the left field but then there's another twist and i was right!!

The usual qualms about Agatha Christie's books: there are some casual racism, XENOPHOBIA, fatphobia, AND uglyphobia. Ms. Christie was never afraid in making her characters calling other character "ugly fuckers" and as an ugly person i'm personally offended and I'm only half joking.

Btw there's romance elements in this book and I actually like it. Because they're just casual flirting and talking stage that feels natural, nothing too dramatic like her usual romance.

Okay, I get that this isn't a GREAT Christie mystery. The sleuthing detours felt haphazard and the ending became very convoluted. Still, I had a fun time consuming it! I've been in a reading rut lately, and this revitalized my interest in audiobooks, and Christie in particular.

What stood out to be about this story: low stakes, excellent cartoonish characters* (much more fun than the usual brooding suspects!), mediocre pacing, a bizarre act three murder and a conclusion so nonsensical that I accepted it because I couldn't keep track of all the convoluted clues and unlikely solutions!

*deadpan flute-obsessed doctor having some kind of affair; zany mystery writer obsessed with the murder weapon; indistinguashable father/son acheology nerd duo turned arranged employer/love interest?; cartoonishly villainous dentist with bipolar behavior who provides internal monologues (!) on multiple occasions; coke obsessed chorus girl turned duchess, and the random horse girl who wants her husband; TWO lost daughters who kind of matter but mostly don’t, plus the bored hairdresser main character you assume is one of those two but is actually a nobody, lol… and a little Belgian detective investigating the case with the police despite his CLEAR conflict of interest as a possible (even likely) suspect! A ridiculous, if occasionally tedious, DELIGHT, I tell you!

Serious side note, though: the version I listened to seemed to censor at least one very extreme instance of racism (and fatphobia!) that occurs as a bonding moment between two main characters. I learned about it later while reading a Goodreads review and was genuinely SHOCKED at its casual, intentional, and blatant awfulness. That lowers the score quite a bit for me and leaves a bad taste in my mouth about the fun and frivolous aspects of the story that I enjoyed.

As always a lot of its time elements. Other than that a change in settings was nice and the storyline was quite interesting. Although after reading two of her books involving dentists I think she was really scared of dentists for no reason.

Norman gale(bale?) i forgot his last name was easy to guess in my opinion. I figured out that it had to do with giselles daughter or her husband and decided that Norman was probably the husband after Anna(?)'s death
