Murder on the Orient Express is the third book of Agatha Christie that I've read. The first one is the infamous And Then There Were None and the second one is The Seven Dials Mystery. And, after I finished reading it, I think this book is definitely one of the best detective stories I've ever read.

As the title clearly explains, the story is about a murder case in the train Orient Express. On the second night of the long departure, a rich old man was killed with twelve stab wounds on his body. And the train also forced to stop because the railway was blocked by the snow. The main character of the story, Hercule Poirot, a famous detective also happened to board the train and involved himself in solving the case. Knowing that there's no way the murderer had fled from the train because of the snow, it is now Poirot's job to find the murderer among the train's passengers.

Now, you might think this is just another story with classic detective formula that's been used like million times by writers. But if you're reading Agatha's novels, you know you're in for a treat of grand plot twist. And yes, just like the one in And Then There Were None, this book has a mind-blowing plot twist in the end.

One of the things that make Agatha Christie's stories interesting is that they always involve a lot of characters (from what I've read, anyway). And by a lot, I mean unusually lot. Especially for something as "simple" as one murder case on a train, for this case. But that is what makes Agatha's stories specials. It's how she writes the dynamics between characters and all of their interactions and behaviors to great details, that makes the story and, ultimately the plot twists, work.

Overall, Murder on the Orient Express is simply great and I regret not reading it sooner.
