Sebastian Moran
The second most dangerous man in London, captured after shooting a wax effigy of Sherlock Holmes with a silenced air rifle.
Colonel Sebastian Moran is a fictional character created by Arthur Conan Doyle, serving as the primary antagonist in the 1903 short story 'The Adventure of the Empty House'. Sherlock Holmes famously described him as 'the second most dangerous man in London,' ranking just below his employer, Professor Moriarty. Born in London in 1840 to Sir Augustus Moran, a former Minister to Persia, Moran attended Eton College and the University of Oxford before pursuing a military career. He served with distinction in the 1st Bangalore Pioneers (Madras), participating in the Jowaki Expedition (1877–1878) and the Second Anglo-Afghan War. His service included action at the Battle of Char Asiab on 6 October 1879, where he was mentioned in despatches, as well as the Battle of Sherpur on 23 December 1879 and the conflict at Kabul.

Verified Timeline
Lore & Background
A devoted sportsman and author of 'Heavy Game of the Western Himalayas' (1881) and 'Three Months in the Jungle' (1884), Moran was known for his extreme skill as a shot, once reportedly crawling down a drain after a wounded man-eating tiger. Despite no open scandal following his turn to crime, he was obliged to retire from the army and return to London. Outwardly respectable with an address in Conduit Street, Mayfair, and memberships in the Anglo-Indian Club, Tankerville Club, and The Bagatelle Card Club, he served as Moriarty's chief of staff. His role was specific: executing assassinations requiring his rifle skills, such as the suspected killing of Mrs. Stuart in 1887. In 'The Final Problem' (set in 1891), Moran escaped incrimination and followed Moriarty to Reichenbach Falls, attempting to kill Holmes by rolling boulders upon him. Later, he earned a living playing cards until Ronald Adair noticed his cheating and threatened exposure. In response, Moran murdered Adair with a silenced air rifle firing revolver bullets.
In Their Own Story
The trap was set at 221B Baker Street, where Dr. Watson and the returned Sherlock Holmes awaited the return of their arch-nemesis. Across the street, in a vacant house, Colonel Sebastian Moran positioned himself to fire his specialized air-rifle. The weapon was designed to be silent, firing small pellets that mimicked revolver bullets, intended to make the death look like natural causes or an accident. Moran took aim at what he believed was Holmes's silhouette. With cold precision, he pulled the trigger. The shot struck true, but not flesh; it shattered a wax effigy of the detective that Holmes had placed in the window as bait. Before Moran could process the failure, the room filled with movement. Holmes, Watson, and Inspector Lestrade emerged from their hiding spots to seize him. This moment marked the end of Moran's reign of terror, capturing the man who had orchestrated Adair's murder and attempted to kill Holmes multiple times.
Reader's Guide
To understand Colonel Sebastian Moran is to recognize a man defined by military precision and lethal marksmanship. He is not merely a thug but an educated officer turned assassin, recruited by Professor Moriarty specifically for his ability to hit targets with a rifle where others failed. His background in the 1st Bangalore Pioneers and his experience as a big-game hunter provided him with the discipline and skill necessary to execute high-profile assassinations. Moran's primary threat lies in his use of specialized weaponry, particularly the silenced air-rifle, which allowed him to kill without leaving traceable evidence or making noise. His downfall in 'The Adventure of the Empty House' illustrates that while his physical skills were unmatched, he could not outthink Sherlock Holmes. By anticipating Moran's method and location, Holmes turned Moran's own weapon against him, leading to an arrest by Inspector Lestrade without a direct confrontation.
