博客來When a brilliant engineer vanishes beneath the streets of London, Sherlock Holmes must descend into the city’s darkest depths to uncover a conspiracy that threatens the very foundations of Victorian society.
Thomas Vintry was investigating irregularities in London’s sewage system when he disappeared without a trace. His only clue: a cryptic telegram warning of ＂the old river＂ and hidden proof beneath the Adelphi Buildings’ labyrinthine coal vaults.
But as Holmes traces the missing engineer’s path through brick-lined tunnels and forgotten Victorian infrastructure, he discovers more than unauthorized sewage diversions. With corrupt property developers, murdered Port Authority officials, and the abyss of absolute darkness, Holmes must risk everything in a harrowing pursuit through London’s subterranean maze-where one wrong step could send him plunging into the ancient rivers that still flow beneath the city’s streets.
From the gaslit parlors of Baker Street to the depths of Victorian London’s most vital and vulnerable systems, this case delivers classic Holmes detection with pulse-pounding adventure-a tale of corruption, courage, and the thin line between civilization and catastrophe.
