A Study in ViolinWillingly, Sherlock Holmes has started 3 relationships in his life: The one he used to have with drugs -violently called off as soon as he wasn't too high to realize he was no longer the owner of his most precious organ, his brain- the one he has with his Violin -he was close to turn into a concert master, but the life of the musician lacked the excitement his job had- and the one with the army doctor whom he shares flat with: John Watson.
He could also state his job was a fourth willing ship he commanded, but his job wasn't just a relationship, his job was his life. His job had brought him everything he has now, so if he should label his job, he wouldn't label it as a mere relationship. It was more, much more.
But then, so were his so called "relationships". When he abused cocaine, he was young, bored, and didn't want anything from this stupid world, filled with ordinary people, stuffed -like Christmas's turkeys- with poison to throw at him. Freak. That wouldn't believe him.
