- Chief Inspector Greyson: Oh, no! Not that dead detective!
- Inspector Beth Lestrade: Yes sir...
- Chief Inspector Greyson: That's all I need: a mayor crisis and a mayor meddler.
- Inspector Beth Lestrade: Deidre, if you were looking to buy a rare African doll with no questions asked, where would you go?
- Deidre: Try the Curio shop on Oxford circle near the tube. But don't tell that Zed-head owner it was me who told ya.
- Inspector Beth Lestrade: No way, Miss Anonymous, and, eh, thanks.
- Chief Inspector Greyson: Is that scruffy little informant properly registered with the Yard?
- Inspector Beth Lestrade: Sometimes, sir, the best information comes from unregistered sources.
- Sherlock Holmes: [to Watson] Now I suggest you help Lestrade escort our imobilized captor straight to New Scotland Yard's strongest jail.
- Inspector Beth Lestrade: I set a Yard record tracking down that perp. How did you get here first?
- Sherlock Holmes: Eyes and brains, Lestrade.
- Chief Inspector Grayson: Er, Lestrade, not a word of this to the, eh, Prime Minister, eh? Heheh.
- Inspector Beth Lestrade: Oh, of course not sir... now, about that submersible I requested last month?
