Promises Series

After the Fall, Sherlock spends all of his time tracking down Moriarty's associates and exterminating them. During his last hit, he stumbles upon the last thing he'd expected - a teenage girl. Julia is more insecure than she lets on, and in more danger than either of them realize. Meanwhile, Sherlock has to work to win back John's friendship. Enter Mary Morstan, who only makes the task more difficult.
