Mark Gatiss and Steven Moffat included a very lovely Terry Pratchett shout out in Sherlock: The Abominable Bride. When Sherlock is tossing out names for the case, he suggests “The Adventure of the Invisible Army? The League of Furies? The Monstrous Regiment?”
Okay, okay. I know that Monstrous Regiment of Women is the title of a Mary Russell/Sherlock Holmes novel by Laurie R. King, and before that “A First Blast Against the Monstrous Regiment of Women” is a work of political philosophy by sixteenth-century reformer John Knox, but I still think Moffat and Gatiss were referencing the late Sir Terry.
