I know you’re an Army doctor, and you’ve been invalided home from Afghanistan. I know you’ve got a brother who’s worried about you, but 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 walked out on his wife, and I know 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 the address is 221-B Baker Street. Afternoon.
