As the literary world mourns the death of Len Deighton at 97, The Mirror's resident book critic provides the definitive guide to his books in order and the grit of his espionage masterpieces

If you think of 1960s espionage, your mind likely jumps to James Bond: martinis, tailored suits, and gadgets that defy physics. But in 1962, a London-born author named Len Deighton published a novel that stripped the glamour away, replacing it with the cold, bureaucratic, and gritty reality of the Cold War. That novel was The Ipcress File, and it changed the genre forever.

The literary world is currently reflecting on the incredible legacy of Len Deighton, who passed away on March 15, 2026, at the age of 97. A true titan of British letters, Deighton was the son of a chauffeur and a part-time cook, a background that gave him a keen eye for the class-conscious absurdities of British life.

Before he redefined the spy thriller, he was a trained illustrator and a gourmet, famously writing the "Cookstrip" for The Observer. His death marks the end of an era for a writer who didn't just tell stories about spies—he told stories about the humans behind the dossiers.

What are the Ipcress Files?

The "Secret File" series is celebrated for introducing an "anti-Bond" protagonist. Unlike 007, Deighton’s hero (who remains unnamed in the books, but became "Harry Palmer" in the Michael Caine films) is a working-class, cynical, and slightly rebellious officer.

These books are famous for their "dossier" style, utilizing footnotes and technical appendices to make the fiction feel like a declassified government report. It’s a world where the real enemy isn't just a foreign power, but the internal red tape and the superiors who look down on the protagonist’s grammar-school education.

Long before celebrity chefs were a staple of culture, Deighton gave his spy a passion for gourmet cooking. This was a way to show a man seeking control and sensory pleasure in a world of grey deception.

Deighton believed that "a man who can't cook is a man who can't think," and his protagonist’s habit of grinding his own coffee beans and shopping at local markets became a signature of the series, grounding the high-stakes world of espionage in the relatable details of daily life.

Ipcress Files

To honour the memory of this master of the genre, many readers are returning to the original "Secret File" novels. Here is the best way to experience the journey of the unnamed spy:

• The Ipcress File (1962): The essential starting point, where the spy battles brainwashing and bureaucracy.
• Horse Under Water (1963): A deep dive into sunken Nazi treasures and drug smuggling.

• Billion-Dollar Brain (1966): A look at a private intelligence agency using early, high-tech computer systems.
• An Expensive Place to Die (1967): A gritty exploration of French nuclear testing and Parisian secrets.
