Unfolding in 1870s Oxford and adventuring abroad, the series will expose the early antics of the anarchic adolescent who is yet to evolve into Baker Street’s most renowned resident.”The year is 1870, when a 19-year-old, naive and inexperienced Sherlock is studying at Oxford University. After a harrowing murder threatens his freedom, he sets out to catch the killer, taking on his first-ever case before becoming the experienced sleuth from Doyle's works we know today.Young Sherlock reimagines the iconic detective in his growing-up years, inexperienced and still learning the nitty-gritties of his profession.
