The Adventure of the Engineer's Thumb, one of the 56 short Sherlock Holmes stories written by Sir Arthur Conan Doyle, is the ninth of the twelve stories collected in The Adventures of Sherlock Holmes. The story was first published in Strand Magazine in March 1892. Dr. Watson notes that this is one of only two cases which he personally brought to the attention of Sherlock Holmes.The story, set in 1889, mainly consists of a young London consultant hydraulic engineer, Mr. Victor Hatherley, recounting strange happenings of the night before, first to Dr. Watson, who dresses the stump where Mr. Hatherley's thumb has been cut off, and then to Sherlock Holmes himself.Hatherley had been visited in his office by a man who identified himself as Colonel Lysander Stark. He offered Hatherley a commission at a country house, to examine a hydraulic press used, as Stark explains, to compress fuller's earth into bricks. Stark warned Hatherley to keep the job confidential, offering him 50 guineas (£52 10s, an enormous sum at the time, worth over £4000 today). Hatherley felt compelled to take this work, despite his misgivings, as his business was newly established and he had very little work.Famous works of the author Arthur Conan Doyle's: "A Study in Scarlet", "Silver Blaze", "The Hound of the Baskervilles", "The Yellow Face", "A Scandal in Bohemia", "The Red-Headed League", A Case of Identity", "The Boscombe Valley Mystery", "The Five Orange Pips", "The Man with the Twisted Lip", "The Blue Carbuncle", "The Speckled Band", "The Engineer's Thumb", "The Noble Bachelor", "The Beryl Coronet", "The Copper Beeches" and many more.
