Review summary
In Prague, Robert Langdon attends noetic scientist Katherine Solomon's lecture before a murder, her disappearance, and a stolen manuscript pull him into a conspiracy about human consciousness.
Full review
The Secret of Secrets brings Robert Langdon to Prague for a lecture by Katherine Solomon, a noetic scientist with whom he has begun a relationship. Her forthcoming book proposes disruptive discoveries about human consciousness, and a brutal murder followed by Katherine's disappearance turns those ideas into a chase for her life and manuscript.
Prague's mystical reputation supports a characteristically Brown mixture of ancient symbolism and futuristic research. The story later widens toward London and New York, but its central tension remains whether consciousness can be explained, extended, or manipulated by institutions determined to control Katherine's work.
Langdon returns through Prague
The city supplies cryptic architecture, folklore, and hidden spaces while noetic science gives the mystery a modern intellectual target. Katherine is personally important to Langdon rather than simply another specialist assigned to the case.
Series order and scale
This is Robert Langdon book six, following Origin. Its case can be read alone, although readers of The Lost Symbol will recognize Katherine Solomon and understand more of her history.
Key ideas
- Scientific claims about consciousness challenge institutions that depend on fixed definitions of the human mind.
- Love increases Langdon's urgency while making objective judgment harder.
