Quote context

[...]

- I'm not interested in whether a racketeer like Lime was killed by his friends or by an accident. The only important thing is that he's dead. I'm sorry.

- Tactful, too, aren't we, Callaghan?

- Calloway.

- Must you take those letters?

- Yes, I'm afraid so. They're Harry's.

- That's the reason.

- You won't learn anything from them. They're only love letters. There are not many of them.

- They'll be returned to you, Miss Schmidt, as soon as they've been examined.

- There's nothing in them.

- Harry never did anything. Only a small thing once, out of kindness.

- And what was that?

- You've got it in your hand.

- Major Calloway. Finished?

- Yes.- Okay.

- You will have to come with us, Miss Schmidt.

- You're not locking her up.

- Go home, Martins, like a sensible chap. You don't know what you're mixing in. Get the next plane.
