Introduction
This one surprised me.
Not because it was Agatha Christie—I knew she was good. But because The Mysterious Affair at Styles, her very first published novel back in 1920, still managed to outwit me more than a century later.
This book marked the debut of Hercule Poirot, a retired Belgian detective with impeccable manners and an ego to match his mustache. And while I expected a classic whodunit, what I got was a cleverly layered mystery, full of red herrings, sharp banter, and a killer twist that I didn’t see coming.
I gave it a solid 4.5/5. Not because it’s perfect, but because it’s iconic—and a reminder of why mystery fiction, when done right, never gets old.
Rating: 4.5/5
Summary of the Plot (No Major Spoilers)
Here’s the setup: a wealthy heiress is found dead in her locked bedroom—poisoned. Everyone in the house has secrets, a motive, or both. Enter Poirot, who, though retired and slightly eccentric, begins piecing the puzzle together using “the little grey cells” in that brilliant head of his.
Our narrator is Captain Hastings, a loyal friend to Poirot and a delightfully clueless Watson-type, who provides just the right amount of dry humor and human perspective.
There are love triangles. Mysterious prescriptions. Suspicious wills. A secret quarrel no one wants to talk about. And underneath it all, that delicious sense of “someone here knows more than they’re saying.”
My Thoughts
The Reading Experience
Reading The Mysterious Affair at Styles felt like stepping into a grand old manor house: cozy, a little dusty, and hiding something in every room.
I read it on a quiet weekend, and I remember pausing now and then to guess the killer, only to be proven wrong every single time. Christie doesn’t play fair—but in the best way possible. Her clues are there. But so are her distractions. It’s the literary equivalent of a magic trick.
And let’s talk about Poirot—he’s not the action hero type. He’s the sit-and-think type. But watching him work is oddly thrilling. You can practically hear the gears turning as he sorts through facts, questions, and human behavior.
Writing & Tone
Christie’s writing is surprisingly modern for something over a century old. It’s straightforward, observant, and occasionally witty. Hastings’ narration gives it a casual air that balances out Poirot’s dramatic flair.
There’s something comforting about her pacing too. The tension builds steadily, and just when you think you’ve figured it out—boom! A new piece of evidence changes everything.
Themes & Reflections
Underneath the murder and mystery lies a fascinating commentary on wealth, trust, and the facades people wear. Every character seems like they could snap if pushed hard enough.
And for a debut, this novel shows remarkable control. It’s not about gore or violence. It’s about psychology. Intent. Motive.
It reminded me that sometimes the deadliest weapons are words, secrets, and silence.
Favorite Line
“Instinct is a marvelous thing. It can neither be explained nor ignored.”
Audience Appeal
If you’ve ever enjoyed a Knives Out movie, a game of Clue, or the thrill of flipping back a few pages to double-check a suspicious alibi—you’ll enjoy this book.
It’s perfect for:
- Fans of classic mystery and detective fiction
- Anyone who loves solving puzzles
- Readers looking for a quick but layered story
- People who enjoy character-driven suspense

Final Thoughts
The Mysterious Affair at Styles isn’t just a great mystery—it’s the start of something legendary. It introduces Poirot, yes. But more than that, it introduces us to Agatha Christie’s signature style: clever, deceptive, and deeply human.
Would I read it again?
Absolutely. Preferably in autumn, with tea and thunder in the background.

Without hesitation.
And hey—if you do read it, let me know: Did you guess the killer?
Because I sure didn’t.
