Dempsey's rental car, a white Mercedes convertible paid for by using O'Grady's credit card, has the registration number A882 JLB.
Dempsey: It's my hunch, but it's your butt too. I'm out of ideas, it's your country. You think of something.
Makepeace: You? Order me?
Dempsey: You're damn' right. I'm a lieutenant and you… are just a sergeant.
Makepeace: We… don't have lieutenants!
Dempsey: You've got one now.
Makepeace: Well, I'm not taking orders from him.
Makepeace: With the greatest respect lieutenant, there are several flaws in that argument.
Dempsey: Believe me sergeant, believe this. [ He taps his nose. ] Believe the nose, the nose knows. I'm telling you.
Makepeace [ discussing their cover as a married couple ]: Somehow, I don't think this is going to work.
Dempsey: Why is that?
Makepeace: I mean, how can we carry this off if we don't even like each other?
Dempsey: Who says we have to like each other? Lots of married couples hate each other's guts. We could be one of them.
Spikings: Sergeant Makepeace would be a good detective to show you around.
Dempsey: Suppose we don't get along?
Spikings: Oh, I think you'll get along.
Spikings: Where did you get that fancy car you arrived in?
Dempsey: I rented it at the airport.
Spikings: How long do you intend to keep it?
Dempsey: Until O'Grady stops paying for it.
Spikings: When will that be, do you think?
Dempsey: Depends on how guilty he feels about me.
Spikings: I will never feel that guilty, lieutenant.
Dempsey: I hope not.
Spikings: And I don't accept threats, from anyone!
Dempsey: Neither do I.
Spikings: Least of all… Yanks!
Spikings: Are you offering me a bloody yank?
Dempsey: What have I got to lose? I'm next on the list, right? If I'm gonna go down, I'm gonna take Coltrane with me!
O'Grady: Because you feel bad about Joe?
Dempsey: Not as bad as if he had shot me.
Joey: This could be the big one!
Dempsey: Now where have I heard that before?
Joey: You don't believe me, do you?
Dempsey: You stink of yesterday's booze, Joey.
