[Casey is posing as a blackmailer]
Louise Bamf: I heard what you said to Mr. Whittaker this morning. The partitions are thin; voices travel.
Casey Jones: Especially through keyholes.
Louise Bamf: Mr. Whittaker has a heart condition. He's had too much excitement as it is... first the robbery, then you. I don't want him to have any more.
Casey Jones: That's very touching. Would you remind me to send him a get-well card?
Louise Bamf: What kind of woman are you? Don't you care about a person's health - whether he lives or whether he dies?
Casey Jones: I care about my health, honey. It just gets better with every dollar I have in the bank.
Lieutenant Bergen: Mr. Whittaker threw the blackmailer out. Apparently he wasn't worried, but you were. Why?
Louise Bamf: Well, I thought if the police came around asking questions he might get upset...
Lieutenant Bergen: Upset about what? His secretary being a thief?
