Charlotte Holmes (a Sherlock fanfic)

John Watson is best friends with the now-famous Sherlock Holmes. Sure, he knows his older brother, Mycroft Holmes. But, who he doesn't know is Sherlock's sister, Charlotte. That's probably because she was dead, or at least she was supposed to be. But, when Charlotte somehow walks again, it's the least of their problems. A storm is brewing right under their noses. Bombings. Murders. Horrible killings, and by who? They'll just have to find out.
