Quote context

[...]

- I'm glad you're convinced.

- I didn't say that, but it is a theory.

- My facts seem to have gone wrong.

- Now tell me what you know about this man who is supposed to be an Egyptian.

- What man?

- The one that's just taken the big house past the nursing home.

- An Egyptian?

- So the locals say. Though it's my belief they wouldn't know an Egyptian from a Chinese acrobat.

- But what's an Egyptian doing here?

- That's what I asked myself.

- Didn't you ask him?

- Mr Banning, if he tells me he's over here to grow mushrooms, I'll have to accept it. And he's not likely to say he's over here to murder a few people.

- Don't you know anything about him?

- Nothing. I don't even know if he's really Egyptian.

- I could find out.

- No doubt, but you're not going to.

- This must tie up. It's too great a coincidence.

- If he's up to something, you'll be placing yourself in danger.

- I know, it's your own neck. But, at the moment, I'm partially responsible for keeping it where it belongs.
