5 Most Popular Agatha Christie Books to Read
If you are unsure where to start or what to read next when obtaining your free Agatha Christie books, below are five of her best works to try. Of course, reasonable minds may differ when choosing the best of anything. However, the following books are generally considered to be five of the most popular Agatha Christie books.
Readers who are new to Agatha Christie’s mystery novels should start with her best selling novel, And Then There Were None or the most widely read mystery novel of all time, Murder on the Orient Express.
Murder on the Orient Express
Murder on the Orient Express is the most widely read mystery novel of all time.
By night, the famous Orient Express train is stopped in its tracks by a snowdrift. By morning, millionaire Samuel Edward Ratchett is found dead in his cabin, having been stabbed a dozen times with his door locked from the inside. One thing is clear — one of his fellow passengers is the murderer.
Isolated by the storm with only each other, detective Hercule Poirot must find the killer among a group of Ratchett’s enemies, before the murderer strikes again in this wildly classic “whodunnit.”
And Then There Were None
Ten people, each of whom has something to hide and something to fear, are invited to an isolated mansion on Indian Island by a host who, to their surprise, never arrives. On the island, they are cut off from the world and only have each other as companions. But, one by one, as the guests share their dark secrets, one by one, they die.
Who among them is the killer and will anyone survive in this locked room mystery book? This is a MUST read.
Death on the Nile
In Death on the Nile, the tranquility of a luxury cruise along the Nile River is shattered by the discovery that Linnet Ridgeway has been shot and killed. She was young and beautiful, and she seemingly had it all.
Hercule Poirot recalls an earlier outburst by a fellow passenger: “I’d like to put my dear little pistol against her head and just press the trigger.” Yet under the harsh rays of the Egyptian sun, nothing is what it seems. There’s love, jealousy, and betrayal in this timeless book. It’s a great story with lots of intrigue.
The Murder of Roger Ackroyd
The Murder of Roger Ackroyd was voted by the British Crime Writers’ Association as the “Best Crime Novel of all Time.”
Roger Ackroyd knew too much. He knew that the love of his life poisoned her terrible first husband. He also suspected that someone was blackmailing her. Then came the tragic news that she took her life by way of an apparent drug overdose.
The evening post brought Roger one more bit of information, but before he could finish reading the letter, he was killed.
Roger’s friend Hercule Poirot must come to town and take over the investigation in this brilliant mystery.
The ABC Murders
In The ABC Murders, a serial killer is on the loose, and he’s working his way through the alphabet, leaving the entire country is in a state of sheer panic.
A is for Mrs. Ascher in Andover, B is for Betty Barnard in Bexhill, C is for Sir Carmichael Clarke in Churston. And with each murder, the killer becomes more confident.
There’s a trail of deliberate clues taunting the proud detective Hercule Poirot to make a fatal mistake.
Those are the best places to get Agatha Christie books for free, as well as her most popular books to help you decide what to read first or next. To recap, the ones I most recommend for ease of access and selection are your local library and Amazon / Audible, which all have numerous reading options.
