The Adventures Of Sherlock Holmes - Volume 7 From The Invisible Empire Files

By Martin Swan

In The Adventures of Sherlock Holmes - Volume 7: From the Invisible Empire Files, the great detective confronts espionage, coded ciphers, and shadowy enemies who manipulate nations like pieces on a chessboard.

In The Adventure of the Blue Cigarette Case, a diplomat's mysterious death and a cipher etched into silver draw Holmes and Watson into the dangerous intrigues of Prague and London's secret societies.
In The Mystery of the Midnight Tram, Holmes unravels a plot of industrial sabotage, political corruption, and illusions crafted by the enigmatic stage magician Dr. Umbra - a master of deception whose allegiance lies with forces bent on destabilizing the Empire.

From smoke-filled theatres to the looming towers of Battersea Power Station, Holmes and Watson chase clues through a London where progress and conspiracy intertwine. As the Invisible Empire's plots unfold, Holmes must pit logic against illusion, and reason against shadow, to protect Britain from a hidden enemy that thrives in misdirection.

A gripping continuation of The Shadows of Progress saga, this volume delivers espionage, betrayal, and high-stakes deduction for fans of Conan Doyle's style and modern historical thrillers alike.
