Holmes tells Oliver that he makes 3,000 pounds a year, plus, he's the favorite of his 94-year-old Aunt Agatha who's worth hundreds of thousands of pounds.
The name of the agency is Cupid's Bow Marriage Bureau and J. Oliver is the manager.
Oliver: Edna, listen to what I'm telling you and see if you can do it right. Stand right here, and if either of them makes a move, scream. Can you do that?
Edna: Yes Mr. Oliver.
Oliver: Good. (to Watson and Lestrade who are tied up in chairs) She's awfully stupid, but she can scream.
Holmes: I was just admiring your Toulouse-Lautrec.
Oliver: My what?!
Holmes: Your Lautrec. Uh, it's very interesting. (pointing at the wall) The painting.
Oliver: Oh, the painting. Of course, of course.
