Currently taking place on Twitter, the BBC is hosting a Sherlock Live event, encouraging mystery fans to try out their own powers of deduction. The interactive Twitter experience consists of the BBC 1 account tweeting clues and other details of a case for followers to collect and solve.
The campaign also serves to advertise their show Sherlock, a contemporary version of the stories by Arthur Conan Doyle starring Benedict Cumberbatch and Martin Freeman, which recently began a new season. Sherlock Live (or #SherlockLive) began at 8pm GMT on Tuesday, January 10th. The mystery you can solve online is a clever way to engage with fans of the program as well as incorporating other Twitter users who may see the hashtag trending.
