DOCTOR: I suggest we pool resources, share information, spread panic, and sow the seeds of defeat in the fields of our enemies!

HOLMES: You are a suspect.

DOCTOR: Yes, I usually am.

BENNY: Come on, let's take you home. I'll let you buy me dinner.

WATSON: (laughs) You're terribly forward!

BENNY: Letting you buy me dinner isn't forward. We'll get to the forward bit depending on how nice the dinner is.

DOCTOR: I'm currently lodging in Hampstead, with Professor Litefoot. You may know of him?

WATSON: Not Professor George Litefoot? The eminent pathologist?

HOLMES: (sotto voce) As opposed to all the other Professor George Litefoots in London?

WATSON: It's no good. I haven't the foggiest what's going on.

BENNY: Just nod and look serious. You'll get the hang of it.
