“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.”

“Lie is more worth living, more full of interest when you are likely to lose it. It shouldn't be, perhaps, but it is. When you're young and strong and healthy, and life stretches ahead of you, living isn't really important at all. It's young people who commit suicide easily, out of despair from love, sometimes from sheer anxiety and worry. But old people know how valuable life is and how interesting. - Jane Marple”

“I admit," I said, "that a second murder in a book often cheers things up." - Hastings”

“It's as easy to utter lies as truth”

“You tell your lies and you think nobody knows. But there are two people who know. Yes- two people. One is le bon Dieu - and the other is Hercule Poirot”

“I often wonder why the whole world is so prone to generalise. Generalisations are seldom if ever true and are usually utterly inaccurate.”

“When you find that people are not telling you the truth---look out!”
