As pointed out by Digital Spy, 'The Six Thatchers' could be linked to Doyle's 'The Adventure Of The Six Napoleons', whilst 'The Lying Detective' may be a spin on the book series' 'The Adventure Of The Dying Detective'.
The BBC previously revealed that series four will begin with Cumberbatch's title character "back once more on British soil as Doctor Watson and his wife, Mary, prepare for their biggest ever challenge - becoming parents for the first time".
The show's last series, which also consisted of three episodes, aired in 2014. Cumberbatch and Freeman first played Doyle's iconic characters in 2010.
