神探夏洛克 第四季是一部剧情,悬疑,犯罪片，《神探夏洛克》第四季将于2017年元旦回归BBC1，本季依旧为三集，标题分别为： 第一集：六座撒切尔像（The Six Thatchers）：编剧为Mark Gatiss，导演为Rachel Talalay； 第二集：倒下的侦探（The Lying Detective）：编剧为Steven Moffat，导演为Nick Hurran； 第三集：最后的谜题（The Final Problem）：编剧为Mark Gatiss和Steven Moffat，导演为Ben Caron。
Sherlock waits to see where Moriarty will make his posthumous move. One mysterious case in particular baffles Scotland Yard but Sherlock is more interested in a seemingly trivial detail. Why is someone destroying busts of the late Prime Minister Margaret Thatcher? Is there a madman on the loose? Or is there a much darker purpose at work? Something with its roots deep in Mary Watson's past.
