I loved Agatha Christie’s books when I was a teenager. I read most if not all of her 66 crime novels featuring the detective skills of Hercule Poirot or Miss Marple, and occasionally other characters such as Ariadne Oliver or Tommy and Tuppence. Many years later I still have a few dogeared paperback versions, passed down from my mother’s estate, and look at them occasionally.

Agatha Christie’s writing career spanned more than 50 years, from 1920 to 1974. The majority of her books are set between the two world wars, a period that has been called the Golden Age of detective fiction. They seem old-fashioned today, yet I still find them appealing, and am obviously not alone in this. Her novels are still widely read, and new dramatisations and pastiches of her work and biographies of her life continue to be produced.

What is the secret of their enduring popularity? For me, there are several reasons:

The plots, mostly following a classic “whodunnit” formula, are extremely ingenious. Although there are clues scattered throughout the books, the solutions cannot easily be guessed before the end. It is said that the author herself often did not know the identity of the murderer until she had written the first draft, which seems amazing if it is true.

The books provide an authentic picture of an England that no longer exists – a time when life was simpler and more slowly paced, comfortable middle class families in quaint villages or country houses were supported by domestic servants who knew their place, and male and female roles were clearly defined. Whether you feel some sense of nostalgia for those days, or are thankful they are gone, it is interesting to read about a relatively recent period of English history so different from today.

Agatha Christie’s style is highly readable. She had a remarkable gift for writing with a light and sometimes humorous touch, but without trivialising the serious subject of murder. Her characters, if somewhat stereotyped, are mostly sympathetic. There is no graphic sex or violence in her books, and they are often categorised today as belonging to the “cozy crime” genre – a term which seems to me to devalue them. They are quite short, I think around 60,000 words. Many modern crime novels are twice that length, but personally I find the more concise format more satisfying.

As you can see from its cover image, there are references to Agatha Christie’s work in my own recent novel You Yet Shall Die. Set in rural England between the 1950s and early 2000s, it is a story of family secrets and discovery of a long-ago crime.
