Author's Note: Simpson's was a restaurant where men could play chess while eating. Holmes mentions it in Dying Detective.

"Where do you fancy dinner?"
Sherlock Holmes is plainly not concentrating on the subject at hand.
"Holmes! Holmes? Where do you fancy dinner, I said?"
Holmes blinks lazily and looks up at his friend. "I don't know. Simpson's again, I suppose. Do you feel up for being beaten at chess again?"
Watson shrugs. "I suppose it is my destiny."
"Mmm."
"Holmes, your mind is obviously elsewhere."
Doctor Watson pulls his shirt on and starts out of the Turkish bath dressing room. Holmes smirks, reaching for his trousers. Yes, he thinks, as he pulls his towel off, elsewhere than dinner, certainly.
