[...]

- I told you to go away. This isn't Santa Fe, I'm not a sheriff and you aren't a cowboy.

- You've been blundering around with the worst bunch of racketeers in Vienna, your precious Harry's friends, and now you're wanted for murder.

- Put down drunk and disorderly, too.

- I have.

- What's the matter with your hand?

- Parrot bit me.

- Oh, stop behaving like a fool, Martins.

- I'm only a little fool. I'm an amateur at it. You're a professional.

- You've been shaking your cap and bells all over town.

- Get me the Harry Lime file, and get Mr Martins a large whisky.

- I don't need your drinks, Calloway.

- You will.

- I don't want another murder in this case and you were born to be murdered.
