Agatha Christie. Evil under the sun (№ 421823)

That's what I don't like! That's what I can't tolerate! <... > how people began to behave. They take on something and at the first opportunity throw what they started to grab on to something else! It freaks me out! There's a thing called decency. If you married a woman and made a commitment to take care of her, you should keep your word. Until the end! It's a matter of honor! There have been too many unsuccessful marriages and hasty divorces!
