Agatha Christie — "I have always been a great admirer of Hercule Poirot."

"I don’t think necessity is the mother of invention. Invention, in my opinion, arises directly from idleness, possibly also from laziness—to save oneself trouble."

"I’ve always thought that people who are frightened to show their feelings are inclined to be a bit ruthless."

"The happy people are failures because they are on such good terms with themselves they don’t give a damn."

"If you confront anyone who has lied with the truth, he will usually admit it - often out of sheer surprise. It is only necessary to guess right to produce your effect."

"One of the things I like about living in the country is that I can say anything I like and nobody hears me but the cows."
