Too Secret Too Long Chapman Pincher: The Book That Doubled Down on the Most Dangerous Accusation in British Spy History

Too Secret Too Long Chapman Pincher

Pincher Already Named Him Once. Then He Came Back With More.

If you've read Their Trade is Treachery, you know the core accusation. Chapman Pincher pointed at Roger Hollis — the former head of MI5 — and said he worked for the Soviets. Bold claim. Massive claim. And in 1981, it shook Britain.

Too Secret Too Long is what happened next.

Three years later, Pincher came back. Same target. More detail. More evidence. More force. And if anything, the second book hits harder than the first.

Here's the thing about Pincher. He wasn't a spy. He was a journalist — the kind that governments hated because he kept finding things they'd rather keep buried. He worked the Daily Express for decades. He had sources inside the intelligence world. And once he decided Roger Hollis was his story, he didn't let go.

In this book, Pincher builds on everything from the first — and then pushes further. He names operations that fell apart. He lists agents who got burned. He maps the failures across Hollis's years at the top of MI5 and asks the same question he asked in 1981. Could all of this be bad luck? Or does a pattern this consistent point to one conclusion?

His answer hasn't changed. Someone at the top was feeding information to Moscow. And that someone was Hollis.

Now here's what makes this book interesting to read alongside the first one. Pincher adds something new — the story of a woman trained by Moscow, one of the most effective Soviet agents of the Cold War era, who worked with a skill and reach that matched Hollis step for step. He argues the damage to British intelligence ran on two tracks. And both tracks led back to Soviet penetration at the highest level.

Can you imagine that? Not one mole but a network of damage so deep that MI5 couldn't fully see it from the inside?

Pincher also goes deep into the rivalry between MI5 and MI6. These two agencies were supposed to work together — one handling domestic security, one handling foreign intelligence. But they didn't trust each other. They guarded their own information. They competed. And that competition created blind spots. And those blind spots, Pincher argues, gave a Soviet spy room to breathe for years.

The writing style is exactly what you'd expect from a veteran Fleet Street man. Sharp. Direct. No wasted sentences. He drives his argument with real confidence — some would say too much confidence. And that's where I have to be straight with you.

Some of Pincher's evidence is thin. Not all of it. But some. He builds a pattern and then treats the pattern as proof. Critics pushed back hard when this came out — and they had a point. A pattern of failures can point to bad luck, bad management, or bad decisions just as easily as it points to betrayal. Pincher doesn't give those explanations much room.

But here's why this book still matters decades later. The Roger Hollis question never got a clean answer. An official inquiry in the 1970s looked into it and came out neutral — not cleared, not convicted. The case stayed open in that quiet, uncomfortable way that British institutions handle the things they'd rather not face. And Pincher made sure it stayed open by putting it all back on the table in print.

I gave this four stars on Goodreads. Strong book. Dense in places — Pincher loads this one with names and dates and it demands attention. But the reward for pushing through is real. By the end, you have a sharper picture of Cold War MI5 than almost any other single book can give you.

Read Their Trade is Treachery first. Then read this. Together they tell a complete story about one of the most controversial accusations in British intelligence history.

And they leave you with a question that nobody has answered with full certainty. Was Roger Hollis the most damaging spy in MI5's history — or did Chapman Pincher spend thirty years chasing the wrong man?

Four stars. Essential reading if you care about Cold War Britain, the inner workings of MI5, and the kind of accusations that governments deny but can never fully dismiss.
