The Adventures Of Sherlock Holmes - Volume 4 From The Shadows Of Progress Files

By Martin Swan

From the Shadows of Progress Files comes one of Sherlock Holmes's most perilous investigations yet.

London, cloaked in choking fog, stands on the brink of a new electrical age. But when mysterious fires, unexplained blackouts, and whispered sightings of a phantom figure plague the colossal Battersea Power Station, the city teeters between progress and disaster.

Summoned to unravel a web of sabotage, espionage, and political betrayal, Sherlock Holmes and Dr. Watson uncover coded transmissions hidden in the very currents of the power grid, a foreman held hostage beneath the city's boilers, and a conspiracy that reaches the highest echelons of government.

As the test to unleash Battersea's full power approaches, Holmes races against time to prevent London from being plunged into chaos. But with enemies hidden in the shadows-and a mastermind known only as "Crown Seven"-the detective faces a battle not just of deduction, but of survival.

A tale of industry, intrigue, and looming catastrophe, this volume captures the chilling intersection of Victorian ambition and the dangers of unchecked progress.
