First, a couple of mine: (In my head!canon, all of the women from Sherlock are secretly badass.)
"Hudson's Gang". (PG) Mrs. Hudson and most of the other characters. A short AU story is which Mrs. Hudson is the boss of a criminal organization. ~800 words
"Almost Anyone". (R - WARNINGS for mentions of suicide and rough sex.) Moriarty, Molly Hooper. "The greatest shock of a dead body is how ordinary it looks." And how ordinary it becomes. ~800 words.
More recs: (This is where you discover I'm a huge Molly fangirl and a Molly/Jim shipper, to boot.)
"Home Is Where", by Mad_Maudlin. (PG-13) Molly, Jim. "Home is the place where, when you have to go there,
They have to take you in." ~2,000 words.
"No Surprises", by
rachel2205. (R - references to sex and murder.) Molly Hooper, Moriarty. When Molly discovers the truth about her boyfriend "Jim" she's more intrigued than horrified, and in her search to find him proves herself to be stronger and smarter than anyone thought. ~2,000 words.
Finally, I have to rec the community I co-mod with the lovely Rachel:
sherlockhet. Rachel decided to set it up for me after I wondered to her what a het fan like myself was doing in such a slashy fandom as Sherlock!
There's a lot of great stories about the women in Sherlock posted there, and if you have some you'd like to add, please do! We subscribe to a loose definition of "het", so the barest of connection to co-ed relationships will qualify! Mostly, I'd just be interested to collect more stories about the female characters there, so if you've got a fic about Sally, Molly, Sarah, Mrs. Hudson, Harry, Clara, etc--bring it over!
