Young Sherlock (British TV series)

The series will be directed by Guy Ritchie and will star Hero Fiennes Tiffin as Holmes.

As a 19-year-old at Oxford University, Sherlock Holmes is not yet the master detective he grows up to be. He is raw and unfiltered, and he lacks discipline. A murder at Oxford puts Holmes's freedom at risk, and he sets out to solve his first murder mystery that leads him to a global-level conspiracy.^[1]
