I love the show, and I hate the way all the other imagines/fanfictions I've read portray Sherlock's girlfriend. Thought it was time to change that. (Also this is pre-Reichenbach)
Cora Rose is a... Well she doesn't know what to call it exactly. She has and extraordinary mind, and uses it to solve crimes. On a case, she meets Sherlock Holmes. A man who seems to be exactly like her. At first she hates him. And then her feelings begin to change, slowly but surely. All while a psychotic murderer is running around London.
