The Science of Sentiment (Sherlock x reader)✅

Moriarty still reigns from the grave. He left a whole plan on how to destroy the world...and Sherlock behind when he died. One day Agent Y/n arrives at 221B Baker street to ask for Mr. Holmes and Dr. Watson's help, but there's a catch. Y/n is as smart as Sherlock, maybe smarter. She moves into 221D to be closer to her 'partners', but are they even on the same team. Did Y/n loose someone important to her? Or is she actually a machine for not having the least bit of Sentiment. Why does she call Sherlock, Mr. Holmes and John, Dr. Watson?
You are involved in this story so the basics are
Y/n= Your name
L/n=Last name
