In the vast world of thrillers, Agatha Christie is an entire genre in and of herself. Reading her work feels exactly like entering a high-stakes mental chess match.

She lays out all the pieces and dares you to solve the puzzle before she flips the board, forcing you to question whether you can trust anyone at all in the tiny, claustrophobic world she builds.

Nowhere is this trap better laid than in her 1926 masterpiece, “The Murder of Roger Ackroyd”.

The story takes us to King’s Abbot, a seemingly sleepy English village where gossip travels faster than light (it has its own secret service) and everyone has a secret. Think afternoon teas, neat lawns, and Bridgerton energy – but with rot underneath it.

Our victim is Roger Ackroyd, a wealthy man who knows too much for his own good. He is burdened by the secrets of a wealthy widow/his almost girlfriend who just took her own life to escape a blackmailer. Just as Ackroyd is about to learn the extortionist’s identity, the lights go out. He is found stabbed to death in an armchair inside his locked private study.

Because the village is so isolated, the police realise the killer is an insider living among them. Every polite neighbour, grieving relative, and loyal servant suddenly looks like a suspect.

Enter Hercule Poirot, the quirky Belgian detective with the magnificent moustache who moved to town for a quiet retirement growing vegetable marrows. His retirement plan fails entirely when he gets dragged into the case by Ackroyd’s niece. Poirot finds an unlikely companion in Dr James Sheppard, the local village doctor and our beloved narrator. Sheppard tags along, documenting every interview and physical clue. Through his eyes, we watch Poirot focus on trivial details – like the angle of a chair or a misplaced scrap of a handkerchief – that the police completely ignore.

Christie plays entirely fair; every clue, alibi, and timeline glitch is dropped right in front of your eyes in broad daylight. Yet, she knows exactly how to make you focus on the wrong details and chase red herrings. You will find yourself cross-examining every character in your head, constantly changing your mind about the culprit. Every character seems like they could be the killer, and not at the same time (trust me, I’ve tried to connect the dots and failed miserably).

In fact, the tension builds so beautifully that I completely lost my mind trying to solve the puzzle. I was in my classroom during my orientation, waiting for my course advice, and I got so bored that I decided to continue reading the book where I left off. I was so intrigued that I almost broke a cardinal book-reading rule: skipping ahead to the very last page just to find out who the killer was (yes, I took a book with me to read during my orientation).

The temptation to peek was massive, but I stopped myself, closed my eyes for a second, and decided to finish the whole book the way it was meant to be experienced. That latter choice was definitely the more exhilarating decision. Watching the trap snap shut naturally is worth every single ounce of suspense, and you realise later that you were looking at the entire puzzle completely upside down.

When published in 1926, it caused a massive stir. Traditional critics argued Christie broke the unwritten rules of detective fiction, sparking heated debates over whether she was a genius or a cheat.

But that controversy is exactly why the book has stood the test of time for a century. Christie expanded what a mystery novel could be, challenging predictable formulas with direct, sharp prose. In an era of gritty thrillers, it serves as a powerful reminder that the human mind itself is the ultimate source of suspense. The book is a celebration of intellect, showing how a quirky little man sitting in a room can dismantle a planned crime just by understanding how people tick.

If you want a story that respects your intelligence while turning your expectations upside down, pick up this book. Just remember one piece of advice before you open the first page: when you step into King’s Abbot, believe absolutely nothing of what you hear, and only half of what you see. Turn the pages carefully, keep your eyes wide open, and see if you can beat Agatha Christie at her own game. (Spoiler alert: you probably won’t, but the ride will be spectacular anyway.)
