Agatha Christie
She’s brilliant, she’s insightful, she’s tricky. Agatha Christie is truly the Queen of Mystery.
Agatha Christie wrote over 80 mysteries and detective stories during her long and productive writing career. You can find a full list of her books in order of publication here if you’re curious about the scope of her work. I adore mysteries in general and Agatha Christie mysteries in particular, so over the years I’ve tried to read as much of her body of work as possible.
Why murder mysteries, you may ask?
What good can reading murder mysteries bring to our soul? Well, when we’re talking about detective stories from the Golden Age, we’re actually reading books written as a powerful response to and spiritual antidote for the post-World War era.
In a true Golden Age mystery, you have an environment such as a home or village that is shaken to the core by disorder: a murder. The mystery story is a quest for justice, an unravelling and labeling of the unimportant and important, a journey of restoration. Thus in the end a right order is restored to the environment and family: a mini-triumph of truth over evil and chaos. You can see how this formula appealed to a post-World War readership. And personally I still feel this quest for justice and order appeals to me deeply.
That’s why I advocate reading a good mystery- if you’re the right age and maturity.
For a really good discussion of why Golden Age mysteries are worth reading, listen to The Importance of Detective Fiction from The Literary Life Podcast.
Are all Agatha Christie mysteries equally well crafted?
No. She grew as a writer, and certainly some of her mysteries have much more depth than others.
Are all Agatha Christie mysteries clean?
Well, you’ll never find graphic bedroom scenes. But the careful parent will want to be forewarned that plenty of these mysteries involve plot elements of casual affairs, out of wedlock pregnancies, and adultery. Sometimes, you’ll also find disturbing motivations, twisted narrators, and questionable ethics.
So let’s take a look at some individual Agatha Christie books and what you want to know about as a parent. Note that I will be adding to this list frequently as time allows and I get through my Christie notes.
IMPORTANT: THERE WILL BE SPOILERS!

Crooked House
This is one of my favorite standalone Christie novels. A young man finds himself unwillingly investigating his fiancée’s grandfather’s murder. The whole family is suspect, but if you’re like me you’ll miss-guess the culprit. A masterpiece of distraction.

This is portrayed as more merciful than letting the child be accused of the murder.

One of the Tommy & Tuppence series. The “young adventurers” of The Secret Adversary return in their 70s for a slow-paced espionage meets mystery type story. Not Christie’s best work, this rambling mystery probably wouldn’t interest anyone except diehard Tommy & Tuppence fans.
