Pretty Stranger...Why Are You Following Me? (Sherlock Fanfiction)

Nothing ever happened to Emily Reynolds. Nothing. She was always lonely. No one ever really liked her. Most of her days, she would walk around London alone. Other days she would go to her job as a doctor at Saint Bartholomew's Hospital. Her very kind co-worker, Molly, was the only person she considered a friend to her. One day, while she was out on one of her lonely walks, she caught sight of a man trailing her closely.
