I just saw Paul McGuigan tweet this:

Congrats to @steven_moffat @DavidGArnold @michaelpriceweb and of course @Eilrahc0801 on their Emmy nominations for #sherlock

So I went to investigate. A Study in Pink (no idea why on that episode) got nominated for:

Outstanding Music Composition For A Miniseries, Movie Or A Special (Original Dramatic Score)

Outstanding Single-Camera Picture Editing For A Miniseries Or A Movie

Outstanding Special Visual Effects For A Miniseries, Movie Or A Special

Outstanding Writing for a Miniseries, Movie or a Dramatic Special
