‘Sherlock’ Season 4 Air Date, News & Update: BBC Benedict Cumberbatch Series Revealing Thatcher, Smith, Sherrinford Secrets In New Year 2017?

BBC "Sherlock Season 4" release date according to Mark Gatiss (Mycroft Holmes) comes this New Year 2017. Benedict Cumberbatch (Sherlock Holmes) will then be seen unraveling the mysteries of the 2016 San Diego Comic Con (SDDC) three-key S4 tease: "Thatcher," "Smith," "Sherrinford."

The Mirror cites a Mark Gatiss interview with BBC Breakfast where the "Sherlock Season 4" actor and writer indicated that S4 premiere release date will follow the pattern of previous seasons. Mark Gatiss further confirmed that "Sherlock Season 4" filming has been completed and will throw Benedict Cumberbatch and fellow BBC series cast into life-changing events.

According to Mark Gatiss "Sherlock Season 4" is not only big and chewy. "Sherlock Season 4" will reportedly be the best one yet from the Benedict Cumberbatch series. Among the changes that "Sherlock Season 4" is expected to bring, as Parent Herald cites, will be the death of Mary Watson (Amanda Abbington) and the return of Irene Adler (Lara Pulver) into Holmes' life.

These "Sherlock Season 4" expectations should run alongside revelations on the significance of "Thatcher," "Smith," "Sherrinford." "Sherlock" executive producers Steven Moffat and Sue Vertue with Mark Gatiss teased these keys during the 2016 SDDC.

Some reports further say that "Sherlock Season 4" is the end of the BBC series and Benedict Cumberbatch will play out Holmes' death in S4. However, Deadline reports otherwise.

Citing Steven Moffat and Mark Gatiss, the media outlet reports that "Sherlock Season 4" will bring the climax of Holmes' story but not necessarily the end of the character or the series that Benedict Cumberbatch popularized. This aligns with tease by Mark Gatiss that "Sherlock Season 4" will not be followed by S5 but will have S6.

Benedict Cumberbatch, Mark Gatiss, Amanda Abbington, Martin Freeman (John Watson) and Una Stubbs (Mrs Hudson) will usher in new and returning "Sherlock Season 4" cast when BBC airs the series in January 2017. Do you share the theory that Benedict Cumberbatch will lay Holmes to rest in "Sherlock Season 4?"
