Description
A midnight summons. A secretive employer. And a job that should never have been accepted.
In The Adventure of the Engineer’s Thumb by Arthur Conan Doyle, a young hydraulic engineer is drawn into a clandestine assignment under suspicious circumstances—one that quickly escalates from curiosity to mortal danger. When he emerges with a shocking injury and a story that strains belief, Sherlock Holmes and Dr. John Watson are called upon to investigate.
What follows is one of the most intense and atmospheric cases in the Holmes canon—a tale of deception, hidden operations, and a narrow escape from a fate far worse than failure.
