Dan Brown's Robert Langdon Netflix Series: What We Know — and Every Langdon Book in Order
Robert Langdon is headed back to the screen — and this time it's a Netflix series, not a Tom Hanks movie. On July 10, 2026, Variety reported that Morgan Spector (HBO's The Gilded Age) is in talks to play the Harvard symbologist in Netflix's adaptation of Dan Brown's The Secret of Secrets. Deadline and TVLine matched the report the same day, adding that Rebecca Hall is also in talks for the female lead.
To be precise about what's actually locked in: neither actor has officially been cast yet. "In talks" means negotiations — deals can still fall through. Here's the honest breakdown.
What's Confirmed vs. What's Still in Talks
- Confirmed: Netflix ordered the series in May 2025. It adapts The Secret of Secrets, the sixth Langdon novel, published September 9, 2025.
- Confirmed: Dan Brown and Carlton Cuse (Lost, Bates Motel) co-created the series, with Cuse serving as showrunner and both executive producing.
- In talks (not final): Morgan Spector as Robert Langdon, and Rebecca Hall as the female lead — the missing noetic scientist Langdon races to rescue.
- Reported: Filming is slated to begin in fall 2026 in Prague, where the book is set.
- Not announced: A premiere date. Given the production timeline, don't expect the series before late 2027 at the earliest.
The official logline: Langdon "races against ancient forces and time to rescue a missing scientist and her groundbreaking manuscript whose discoveries have the power to forever change humanity's understanding of the mind."
Why This Is a Bigger Deal Than Another Da Vinci Code Movie
This is the first time a Langdon story gets the long-form treatment on a platform of Netflix's size — the Tom Hanks films (2006–2016) compressed 500-page puzzle boxes into two hours, and the one previous TV attempt (Peacock's 2021 The Lost Symbol prequel) was canceled after a season. A series built by Brown himself alongside a veteran showrunner, adapting the newest book instead of retreading The Da Vinci Code, is a genuinely fresh start for a franchise that has sold over 250 million copies.
And here's the good news if you've never read a single Dan Brown novel: you don't need to catch up before the show. Every Langdon book is written to stand alone. But if you want the full picture — including where Katherine Solomon, the scientist at the center of the Netflix series, first appears — here's the complete reading order.
Every Robert Langdon Book in Order
Six books, published over 25 years. Publication order and chronological order are the same for this series, so this is the only list you need.
1. Angels & Demons (2000)
The book that introduced Robert Langdon, four years before most readers had heard of him. A physicist is murdered at CERN, a canister of antimatter goes missing, and Langdon is pulled into a centuries-old feud between the Illuminati and the Vatican — all while the papal conclave is sealed inside the Sistine Chapel. It's a race across Rome's churches and crypts with a ticking clock, and it set the template every Langdon story follows.
2. The Da Vinci Code (2003)
The phenomenon. A curator is found murdered in the Louvre, posed like a famous da Vinci drawing and surrounded by cryptic symbols, and Langdon becomes both the chief suspect and the only person who can decode what the dying man left behind. The trail runs through Renaissance art, secret societies, and one of the most argued-about theories in modern fiction. Love it or roll your eyes at it, it's one of the best-selling novels ever written.
3. The Lost Symbol (2009)
Langdon comes to Washington, D.C. for what he thinks is a last-minute lecture, and instead finds a gruesome invitation into the hidden world of the Freemasons. His mentor Peter Solomon has been kidnapped, and the only way to save him is to unlock a Masonic mystery buried in the capital's architecture. This is also the book where Katherine Solomon — the noetic scientist at the heart of the new Netflix series — first appears, which makes it the single best bonus read before the show.
4. Inferno (2013)
Langdon wakes up in a Florence hospital with a head wound and no memory of the last two days — and someone is already trying to kill him. The clues this time are woven through Dante's Divine Comedy, and the stakes are a plague engineered by a brilliant scientist who believes humanity's overpopulation is the real apocalypse. It's the darkest of the Langdon books, and the moral dilemma at its center actually lingers.
5. Origin (2017)
A billionaire futurist — and former student of Langdon's — gathers the world's elite in Bilbao's Guggenheim Museum to announce a discovery he claims will answer humanity's two oldest questions: Where do we come from, and where are we going? The announcement never finishes. Langdon spends the rest of the book racing across Spain to release the discovery to the world, with an AI assistant as his unlikely ally. It's the most tech-forward entry in the series, and it reads differently now than it did in 2017.
6. The Secret of Secrets (2025)
The book Netflix is adapting. Langdon travels to Prague to attend a lecture by Katherine Solomon, who is about to publish a manuscript on human consciousness with findings that powerful people would prefer stay buried. When Katherine vanishes and her manuscript disappears with her, Langdon is thrown into a chase through one of Europe's most mysterious cities — golems, alchemists, secret libraries and all — wrestling with the biggest question there is: what happens to us after we die? At 650-plus pages, it's Brown's longest novel, and it debuted at #1.
Publication Order vs. Chronological Order
Unlike a lot of long-running series, there's nothing to untangle here: the Langdon books happen in the order they were published. No prequels, no novellas, no reading-order debates. Each book also stands almost entirely on its own — recurring characters get reintroduced, and past adventures get a sentence of recap at most. So while reading 1-through-6 is the most satisfying path, you can genuinely start with The Secret of Secrets if you just want to read the book before the show arrives.
The pragmatic pre-show reading list, if you only have time for two: The Lost Symbol (Katherine Solomon's introduction) and The Secret of Secrets (the story Netflix is telling).
Where the Netflix Series Might Start
Everything announced points to the series adapting The Secret of Secrets directly rather than starting from Angels & Demons — the logline matches the book's plot beat for beat, and the reported casting of Rebecca Hall lines up with Katherine's central role. That means Netflix is treating the earlier books the way the novels themselves do: as backstory you don't need. If the series lands, though, five more books of material are sitting right there.
