…heralding the one-off "Victorian Special" and three new episodes for Season 4.
And now the bad news: they won't be on our screens until 2017!
In the meantime you can still come and join us on the Sherlock Holmes Walk every Friday.
A London Walk costs £10 – £8 concession. To join a London Walk, simply meet your guide at the designated tube station at the appointed time. Details of all London Walks can be found at www.walks.com.
