Young Sherlock has found its Sherlock Holmes’ older brother, Mycroft. According to Deadline, Max Irons (Condor) has joined the series and will star alongside Hero Fiennes Tiffin’s Sherlock.

The drama revolves around the legendary detective’s younger days. The rest of the cast includes Dónal Finn, who plays James Moriarty, Joseph Fiennes (Silas Holmes), Natascha McElhone (Cordelia Holmes), Zine Tseng (Princess Gulun Shou’an) and Colin Firth (Sir Bucephalus Hodge).

The following was revealed about the plot of the Prime Video series:

Inspired by Andy Lane’s book series, Young Sherlock is described as an irreverent, action-packed origin story of Sir Arthur Conan Doyle’s beloved detective in a re-imagining of this iconic character. At age 19, Sherlock Holmes (Fiennes Tiffin) is disgraced, raw, unfiltered, and unformed, when he finds himself caught up in a murder mystery at Oxford University which threatens his freedom. Diving into his first-ever case with a wild lack of discipline, Sherlock manages to unravel a globe-trotting conspiracy that will change his life forever.

The premiere date of Young Sherlock will be announced later.
