Sherlock Holmes in The Wren Testament (Paperback) (ISBN-13: 9798242224254)

When a sacred relic vanishes from St. Paul's Cathedral, Sherlock Holmes discovers a mystery far deeper than simple theft.

A reliquary has disappeared from a locked vestry, accessible only through Christopher Wren's ingenious Geometric Staircase. But as Holmes investigates, he uncovers evidence that the great architect embedded more than mathematical beauty into his masterpiece-he built a two-hundred-year-old puzzle, designed to challenge future generations.

An American scholar obsessed with hidden codes. A stonemason guarding his family's centuries-old secret. A terrified librarian who has concealed a devastating truth for thirty years. All are converging on St. Paul's, each seeking something different in Wren's architectural labyrinth.

What begins as a routine investigation soon escalates into violence, conspiracy, and a race against powerful forces determined to suppress what Holmes has discovered. For hidden within the cathedral's ancient stones lies Wren's Testament-a document that could shake the foundations of faith itself.
