What Season 1 of Young Sherlock
Oxford, 1870. Sherlock Holmes is 19 years old, studies at the university, and isn't yet the detective readers of Conan Doyle know. He's impulsive, says what he thinks, and struggles to fit into academic discipline. When a murder shakes the city, he becomes the main suspect and his future is at risk, so he decides to investigate on his own. What seems like a local mystery opens up into an international plot. Alongside Moriarty, he faces new murders and missing professors, as well as questions about his own family. Hero Fiennes Tiffin plays the lead in this series created by Matthew Parkhill.
