Blue Murder at St. Trinian's

Sergeant Ruby Gates:
[dancing cheek-to-cheek in a Parisian boite] The French are so romantic!

Captain Romney Carlton-Ricketts:
Yes, but are they sincere?

Sergeant Ruby Gates:
You see, I'm here on a special case

Captain Romney Carlton-Ricketts:
What sort of case?

Sergeant Ruby Gates:
Must I tell you?

Captain Romney Carlton-Ricketts:
I should jolly well think you should! You give me all that guff about being an interpreter, lead me up the garden path...

Sergeant Ruby Gates:
Oh, please don't talk to me like that, Romney! I'm such a crazy, mixed-up policewoman!

Captain Romney Carlton-Ricketts:
Well, how do you think I feel? One second we're swapping sweet nothings to a Neapolitan love song, and the next moment we're up to our nostrils in Agatha Christie. A chap doesn't know where he stands!
