About “Young Sherlock” in a few words:

Young Sherlock is a fresh take on the legendary detective, exploring his teenage years long before Baker Street fame. The story follows a young Sherlock Holmes studying at Oxford, where he stumbles into a web of political intrigue, strange crimes, and secret societies. What begins as curiosity turns into a much bigger mystery, forcing Sherlock and those around him to navigate danger, loyalty, and the fine line between genius and obsession.

Meet the characters from Young Sherlock

Sherlock Holmes

Oh man, Sherlock is this crackling ball of pure brain-energy — brilliant, impatient, kind of delightfully cruel with puzzles and people alike. He’s theatrical in the best way, always a little dramatic (yes, he probably does a dramatic sniff and then writes a note in invisible ink — don’t ask how I know). Social awkwardness? Tons — but somehow he pulls off charisma when it matters, like a cat that learned to smile. He’s fiercely curious, stubborn as a stone, and secretly soft about one or two things he’d never admit; also, he definitely plays the violin at 3 a.m. and claims not to be sentimental while totally being sentimental.

James Moriarty

Moriarty is the deliciously dangerous kind of villain who makes you clap and then regret it, all at once — genius, theatrical, and a little bit of a show-off. He treats crime like chess or a cruel art project, polite on the surface but with a manic grin underneath (have I mentioned the laugh? it’s the kind that gives you chills). He’s obsessively precise, sometimes too charming, and utterly unpredictable — you’ll never know if he’s plotting a lecture or a catastrophe. Also, low-key enjoys poetry in a twisted way and might keep sugar cubes in his pocket for no logical reason.

Cordelia Holmes

Cordelia feels like the warm, secret heart of the whole chaotic Holmes family — tender, quietly fierce, and endlessly patient, which shocks people who expect only Holmes icy logic. She’s the one who anchors the house, baking metaphors into actual bread sometimes (I swear there’s at least one scene where she’s making tea and solving a riddle without even trying). There’s a soft mystery about her past — she’s both worldly and a touch forgetful, like she’s living two lives at once, which is probably dramatic but also kinda adorable. She’ll give you the best advice and then deny it ever happened, totally sincere and yet a little elusive.

Princess Gulun Shou’an

Okay, Princess Gulun Shou’an is an absolute delight — regal, stubborn, sharp-eyed, and not having any of the polite nonsense that comes with being royalty. She’s politically savvy but also has these tiny, surprising hobbies (like carving tiny boats or collecting old matchboxes — don’t ask), and she can read a room faster than anyone. There’s a fierce loyalty dripping from her speeches and then, weirdly, a soft spot for bad jokes and steamed buns, so she’s terrifying and oddly relatable. She fights for her people with strategy and heart, and her tiny rebellions are the best kind — subtle, clever, and kind of thrilling.

Mycroft Holmes

Mycroft is the gloriously smug, all-seeing older brother who sits in a comfy chair and apparently runs half the world, or at least a very important part of it. He’s bureaucratic, annoyingly efficient, and has this dry wit that can cut through steel — and yet he’s also oddly sentimental about tiny things like perfect teaspoons or the exact angle of a hat. He’s almost lazy, except when he isn’t; most of the time he’ll sigh and hand someone a solution like handing over a wrapped-up prophecy. Also, don’t be fooled by the bored stare — he notices everything, and he’ll definitely correct your facts at dinner (politely, of course).
