Prime Video’s Young Sherlock takes audiences back to when the famed sleuthing mastermind was just 19 years old. Though he’s usually the cleverest and sharpest person in any room, Sherlock is still unmistakably a young man with some growing up left to do. When viewers first meet Sherlock Holmes (Hero Fiennes Tiffin), he is behind bars for thieving. Warning: Spoilers ahead for Season 1 of Young Sherlock.

His brother, Mycroft (Max Irons), who has a post in Her Majesty’s Foreign Office, gets his younger brother out of trouble and into Oxford — well, into the janitorial staff at Oxford, at least. It’s still, much, much better than prison. As it stands, Mycroft sees this as a chance to redirect Sherlock’s restless genius into something useful.
