I know you're an army doctor and you've been invalided home from Afghanistan, you've got a brother worried about you, you won't go to him for help because you don't approve of him. Possibly because he's an alcoholic. More likely because he recently walk out his wife and I know that your therapist thinks your limp's psychosomatic, quite correctly, I'm afraid. That's enough to be going on with. Don't you think? the name's Sherlock Holmes, and address is 221B Baker Street.
