Quote context

[...]

- I suppose it wouldn't interest you to know that Harry Lime was murdered. You're too busy. You haven't even bothered to get the complete evidence.

- Must you take those?

- They'll be returned, miss.

- They are private letters.

- That's all right, miss. Don't worry. We're used to it. Like doctors.

- There was a third man there. I suppose that doesn't sound peculiar to you.

- 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.
