A New Chapter for Robert Langdon… and for Prague!
Dan Brown’s highly anticipated sixth Robert Langdon thriller, The Secret of Secrets, arrives on September 9, 2025 – his most intricately plotted and ambitious tale yet. Set in Prague, the story opens with Langdon attending a provocative lecture by noetic researcher Katherine Solomon at Prague Castle’s majestic Vladislav Hall. The novel blends science, mysticism, and conspiracy as Langdon races through Prague’s ancient streets to recover a lost manuscript after a brutal murder.
Acclaimed landmarks such as Charles Bridge, the Klementinum Library, hidden Old Town alleys, and even clandestine speakeasy bars like Black Angel’s have been hinted as key scenes that bring Prague’s historical depth to the page.
The book is scheduled to release on September 9, 2025
Why Prague Makes the Perfect Thriller Stage
Dan Brown has long professed his fascination with Prague, calling it “a labyrinth of enigmatic sites, an ideal backdrop for a Robert Langdon thriller – a city of secrets, both ancient and modern” (Dan Brown Official Website).
With Gothic spires, Baroque architecture, astronomical symbolism, mystical lore, and hidden passageways, Prague offers the perfect setting for a story where every shadow might hold a clue.
Many of the places featured in the book are the very same ones that you can explore on foot today. On our small-group Prague history tours, we guide you through Old Town alleys, Gothic churches, and mysterious courtyards where the city’s past comes alive. See all our tours here.
