What we can learn from James Patterson
James Patterson is one of the most popular crime writers in the world. His books rarely leave the top 10 mass market fiction charts and are sold across the globe. He is an expert in promotion and franchising and has launched a number of very successful joint ventures with other writers to fully exploit his story ideas.
The most successful at the moment is the ‘Women’s Murder Club’ Series.
A series of bestselling novels. A TV series. And now a game appealing to the demographic with the most cash – older women.
So what makes these books so popular?
I would suggest Readability.
James Patterson himself has said that he intended to create a fast paced, page turning fiction form devoid of exposition or lengthy internal angst. And he succeeded.
What exactly IS Readability? Can it be measured? Yes. It can.

The Readability calculations estimate how easy it is to read and understand the text of a book.
The Text Stats feature calculates a variety of statistics for each book.
Text Statistics and Readability Indices from Amazon.Com.
- The Fog Index was developed by Robert Gunning. It indicates the number of years of formal education required to read and understand a passage of text.
- The Flesch Index, developed in 1940 by Dr. Rudolph Flesch, is another indicator of reading ease. The score returned is based on a 100-point scale, with 100 being easiest to read. Scores between 90 and 100 are appropriate for 5th and 6th graders, while a college degree is considered necessary to understand text with a score between 0 and 30.
- The Flesch-Kincaid Index is a refinement to the Flesch Index that tries to relate the score to a U.S. grade level. For example, text with a Flesch-Kincaid score of 10.1 would be considered suitable for someone with a 10th grade or higher reading level.
- A word is considered “complex” if it has three or more syllables.
As I understand it, the US grade system is as follows begins with 1st grade at age 6. Then goes one grade for each year of age.
4th Grade would therefore correspond to a reading age of 9 years old, 5th Grade, 10, and 6th Grade, 11.
A Flesch-Kincaid Index score of 4.8 to 5.7 therefore indicates that a person with a reading age above 11 years could read this book. This is consistent with about 6 years plus of formal school education from the Fog Index.
So, how does it work for The Women’s Murder Club series? Here are a few examples:

First thing to notice?
* these are short books. Most thrillers come in about 90 to 100K at least.
* the syllables per word is remarkably low.
* all of the Index markers would suggest that these books can be read by anyone with a reading age of 11 upwards.
But this does not tell you about the Structure of the books. More detective work needed for that.

Very interesting. The short chapters, easy to read, page turning, thrills are many of the reasons I love Patterson novels and keep coming back for more. I can read one in a day and experience all kinds of emotions while doing so.
