The Secret of Secrets: Dan Brown Is Back — And the Formula Still Works

The Secret of Secrets by Dan Brown

Spoiler Alert — this post contains spoilers for The Secret of Secrets and references to other Robert Langdon novels.

I am a big fan of Dan Brown's Angels & Demons and The Da Vinci Code. Of the two, Angels & Demons is my favourite by a significant margin.

I picked it up first because it's the first book in the Robert Langdon series chronologically, and I like reading things in order. This was shortly after The Da Vinci Code had exploded onto the scene. By the time I got to Angels & Demons, I tracked down the special illustrated hardcover edition — the one with real photographs of Rome and the Vatican woven through the pages. Those visuals made the story come alive in a way the standard edition simply couldn't.

My wife loved it too. So much so that Rome became one of our first trips together — we wanted to visit the locations from the book in person. I have a vivid memory from that trip of arriving at the Piazza del Popolo, which is the setting for one of the novel's most dramatic scenes — a life-or-death struggle in the waters of the fountain. We got there, looked at the fountain, and realized it was completely shallow. The grand cinematic fight scene that had played out so vividly in my imagination was, in reality, physically impossible 😂

Recently I walked into an Indigo bookstore with my family and discovered that Dan Brown had released a new novel — The Secret of Secrets. I've read every book in the Robert Langdon series and I'll be honest — the quality has declined since The Da Vinci Code. I was also never particularly drawn to the Tom Hanks film adaptations. But there's something genuinely nostalgic about picking up a new Dan Brown novel. For me it’s the same when reading a new Hercule Poirot story — even new ones written by Sophie Hannah after Agatha Christie — or returning to a Jack Ryan novel just hits the spot.

The Nostalgia of Robert Langdon Still Works

My main criteria for fiction is simple — I don't want to know how it ends. I want to be surprised, even if I know the protagonist will ultimately prevail. That's a reasonable expectation to bring to any thriller.

The Secret of Secrets delivers on that. Dan Brown follows his established formula closely — exotic historical locale, strategic flashbacks, layers of symbolism, an outlandish central theory, multiple competing factions, and Robert Langdon alongside a new female character as if he's James Bond 😂. Knowing the formula in advance actually made it easier to read, not harder. I knew the structure. I had no idea where the plot was going. That combination works for me.

I've also reached a point in my reading life where if a fiction novel hasn't engaged me after roughly 100 pages, I'm comfortable putting it down. The Secret of Secrets never triggered that instinct.

The Concept of Noetic Science Is Genuinely Interesting

Every Robert Langdon novel is built around a central concept — something big, real and slightly mind-bending that anchors the fictional story in the real world. This one uses noetic science, which I had never heard of before.

Noetic science is the study of consciousness. The central premise of the novel pushes that further — suggesting that consciousness might actually exist outside the human body and brain entirely. Dan Brown supports this with real-world examples that make the idea feel grounded rather than fantastical. He references near-death experiences and Acquired Savant Syndrome — an extremely rare condition where an ordinary person suddenly develops extraordinary abilities in art, music or mathematics, typically following a traumatic brain injury, stroke or severe illness.

This is what Dan Brown does best. He takes a fictional idea and anchors it in documented reality until the line between the two becomes genuinely blurry. It's the same reason The Da Vinci Code caused such a cultural reaction when it was released — people weren't sure what was real and what wasn't because the real elements were so carefully woven in. He does it again here with noetic science, and it works.

What It Can't Match Is the Cool Factor of the First Two Books

Everyone knows Mona Lisa by DaVinci

Here is the honest answer to why Dan Brown's later novels never quite recaptured the cultural impact of Angels & Demons and The Da Vinci Code.

The first two novels had extraordinary subject matter as their foundation. The Illuminati. The Roman Catholic Church. Leonardo da Vinci. These are subjects that carry enormous cultural weight — they've fueled conspiracy theories for centuries, they feel urgent and real, and they have a natural gravitational pull on the reader's imagination. Prague and noetic science, as interesting as they are, simply don't carry the same weight. I can't even remember the central concepts of some of the later books in the series, which says everything.

It's genuinely unfortunate, because Dan Brown's ability to weave real historical detail, symbolism and mystery into his fiction is consistently impressive. The problem isn't his craft — it's that he set an impossibly high bar with his first two subjects.

Final Thought

If you're already a Dan Brown fan and enjoy the Robert Langdon formula, The Secret of Secrets is worth your time. The noetic science concept is fresh, the pacing is tight and the formula delivers what it always delivers.

But the more important recommendation is this — if you have not read Angels & Demons, read it before anything else. And specifically, find the special illustrated hardcover edition. The photographs of Rome and the Vatican alongside the story are genuinely worth the upgrade.

You'll thank me later. And then you'll want to book a trip to Rome 😊
