- Sorry to bother you.

- Bannion just left here.

- No, sir. I just gave him a lot of double-talk.

- He said he'd be back again.

- Yes, sir. I will.

- Okay, buster, who'd you call?

- My mother.

- Would you rather go downtown to answer the questions?

- Don't scare me, Sergeant. Five minutes after we get downtown, you'll be answering the questions.

- Get your coat.

- Sure. Only somebody will want to know why you're butting into a county case, why you don't stop annoying people, especially after you've been told once.

- You get your news fast, don't you?

- Special carrier pigeon.

- Do we still go downtown?

- No. Not today. When we do, I'll have enough answers to close this joint up.
