Why I Let Inspector Harper Grow Old
When I started writing about Harper, I had a choice to make. I could create a detective who never changes, someone who solves a case, closes the file and walks into the next book exactly the same. Plenty of great crime writers have done that, and done it well. There is real comfort in a detective who never ages, never doubts and never loses their nerve.
But that was never the detective I wanted to write.
I wanted someone who would carry every case forward. Someone who would make mistakes, earn promotions, lose things along the way and become a different person by the end. Seventeen books later, I am glad I made that choice, and I want to share a little of why.
Why London
I set the Harper books in present day London because no other city gives a crime writer quite so much to work with. It is ancient and modern at the same time. Wealth sits a few streets away from real hardship. Millions of people pass each other every day without ever knowing what the person beside them is hiding.
London is also a city of contrasts that never sit still. A street can change character in a few years. Old businesses close and new ones open. Communities arrive, settle and move on. For a detective, that means the ground is always shifting. The informant who was reliable last year may be gone. The neighbourhood that was quiet may not be quiet anymore.
That restlessness is exactly what I wanted for Harper. A detective in London can never rest on what they knew yesterday.
Crime That Belongs to Its Time
A modern city means modern crime. I have always wanted the Harper books to feel like they belong to the world we actually live in, not a world of country houses and poisoned teacups, much as I enjoy those stories.
In Death Comes Quickly, the second book, Harper is pulled into the brutal world of drug wars. It is a story about how violence spreads, and how quickly ordinary lives get caught up in it. In The Hacking, the crime leaves no footprints and no fingerprints at all. The criminal may never set foot in the same room as the victim, and Harper has to learn a whole new way of thinking to catch them.
In The Accountant, the seventeenth book, I wanted to follow the money. In my experience, that is usually where the truth ends up hiding. People will lie about where they were and who they saw, but money leaves a trail, and patient detectives can follow it.
The city changes, so the crimes change, and Harper has to keep up. That is one of the great pleasures of writing a long series. The world of the first book is not quite the world of the last.
From Inspector to Commissioner
The part of this series I am proudest of is Harper's career. Harper does not stay a Detective Inspector forever. By The Golden Fleece, the sixteenth book, Harper has become Commissioner, working alongside DCI Bryant.
That changes everything about the stories. An inspector chases suspects through the streets. A commissioner carries the weight of an entire force, along with the politics and the decisions nobody else wants to make. The danger is no longer only a suspect with a weapon. It is a wrong call that affects hundreds of officers, or a public that loses faith in the police.
I found that shift fascinating to write. It allowed me to explore a different kind of courage. Not the courage to run toward trouble, but the courage to stand behind a hard decision and live with the consequences. I hope readers who have followed Harper from the beginning feel the same sense of a life fully lived.
What Really Matters in a Mystery
People sometimes assume crime fiction is all about the puzzle. The puzzle matters, of course. A reader deserves a mystery that is fair, surprising and satisfying when it is solved. But for me, the heart of any good mystery is loyalty. Who stands by whom when it counts. Who breaks under pressure. Who you can trust when the stakes are real.
That theme comes from my own life. I was orphaned during the Second World War and raised in Leicester, and I learned early on what family and loyalty truly mean. Those lessons found their way into Harper's world without my ever planning it. The relationships between officers, and the bonds that hold or snap under strain, are as important to me as the question of who did it.
I have also drawn on the many people I met during my years of military service and my professional life. I have known people from every walk of life, and that has taught me that nobody is simple. The most decent person can be pushed into a terrible choice. The most hardened character can surprise you with kindness. I try to give my characters that same complexity, whether they are wearing a badge or running from one.
Where Should You Start?
Readers often ask whether they need to begin with the first book. My honest answer is yes, if you can. Harper's story builds from one book to the next, and the later novels mean far more when you know what came before. Small moments in early books grow into something much larger later on.
If you would rather dip a toe in first, here are a few suggestions.
- For the full journey, start at the beginning and read in order. You will watch Harper grow from a determined inspector into the head of a police force.
- For something fast and gritty, try Death Comes Quickly. It shows Harper in the thick of street level crime.
- For Harper at the top, jump ahead to The Golden Fleece or The Accountant, then go back and see how it all began.
However you choose to start, I hope you enjoy the company. Harper has been with me for a long time now, and I still find new things to discover with every case.
