“I've always believed in writing without a collaborator, because where two people are writing the same book, each believes he gets all the worries and only half the royalties.”

“I mean, what can you say about how you write your books? What I mean is, first you've got to think of something, and then when you've thought of it you've got to force yourself to sit down and write it. That's all." ~ Mrs. Oliver”

“I was such a foolish girl - girls are foolish, Mr. Satterthwaite. They are so sure of themselves, so convinced they know best. People write and talk a lot of a ‘woman’s instinct.’ I don’t believe, Mr.Satterthwaite, that there is any such thing. There doesn’t seem to be anything that warns girls against a certain type of man. Nothing in themselves, I mean. Their parents warn them, but that’s no good - one doesn’t believe.

“She was a lucky woman who had established a happy knack of writing what quite a lot of people wanted to read.”

“Do you believe in the value of truth, my dear, or don’t you?”“Of course I believe in the truth,” said Rhoda, staring.“Yes, you say that, but perhaps you haven’t thought about it.

“Nowadays, no one believes in evil. It is considered, at most, a mere negation of good. Evil, people say, is done by those who know no better - who are undeveloped - who are to be pitied rather than blamed. But, M. Poirot, evil is real! It is a fact! I believe in Evil as I believe in Good. It exists! It is powerful! It walks the earth!' He stopped. His breath was coming fast. He wiped his forehead with his handkerchief and looked suddenly apologetic. 'I'm sorry. I got carried away.”
