Netflix greenlights Prague-set Dan Brown series based on new novel

Dan Brown’s globe-trotting symbologist Robert Langdon is heading to Prague—and to Netflix. The streaming giant has acquired the rights to adapt Brown’s forthcoming novel The Secret of Secrets into a television series, co-created by Brown and Lost producer Carlton Cuse.

Set to be released simultaneously in English and Czech on Sept. 9, the book sees Langdon plunged into a race against time and shadowy forces after a groundbreaking manuscript vanishes along with its author—a leading noetic scientist and Langdon’s romantic interest, Katherine Solomon.

“This is by far the most complex and ambitious book I’ve ever written, and I also think it’s the most fun,” Brown said in a statement released by the book's Czech publisher Argo.

Details of the plot are still under wraps, but early synopses hint at a high-stakes thriller that explores the boundaries of consciousness and challenges long-held human beliefs.

The story begins in Prague, where Langdon is attending Solomon’s lecture, only for events to spiral into a hunt across the Czech capital, London, and New York. Along the way, Langdon finds himself pursued by a mysterious figure seemingly ripped from ancient Prague legends.

Netflix won the adaptation rights after a fierce bidding war and is partnering with Brown and Lost producer Carlton Cuse. Cuse will co-create, write, and executive produce the series and act as showrunner. Casting is already underway, but Netflix has not yet announced a director or release date.

The novel marks Langdon’s return after an eight-year break since Origin (2017). Previous entries in the series include Angels & Demons, The Da Vinci Code, The Lost Symbol, and Inferno. Three of these books were adapted into films starring Tom Hanks and directed by Ron Howard, earning over USD 2.2 billion worldwide. The Lost Symbol was adapted as a 2021 Peacock series starring Ashley Zukerman.

Brown’s books have sold over 250 million copies in 56 languages, making him one of the most successful authors of all time. In addition to his thrillers, he has written a children’s book, Wild Symphony, accompanied by original orchestral compositions.
