Sherlock had a lucky escape after Mycroft summoned his brother back to England since Moriarty has returned. The only thing Sherlock has been able to think about is not about Moriarty but his blogger, John Watson.
Sherlock Holmes and John Watson have been friends for as long as they can remember. Only when John joins the army and is shipped off to Army camp do they realise they want to be more than friends. Much more.
