“There is no telling what a human character is. Until the test comes. To most of us the test comes early in life. A man is confronted quite soon with the necessity to stand on his own feet, to face dangers and difficulties and to take his own line of dealing with them. It may be the straight way, it may be the crooked way --- whichever it is, a man usually learns early just what he is made of.”

“But I know human nature, my friend, and I tell you that, suddenly confronted with the possibility of being tried for murder, the most innocent person will lose his head and do the most absurd things.”

“A man doesn't want to feel that a woman cares more for him than he cares for her. He doesn't want to feel owned, body and soul. It's that damned possessive attitude. This man is mine---he belongs to me! He wants to get away --- to get free. He wants to own his woman; he doesn't want her to own him.(Simon Boyle)”

“I gather," he added, "that you've never had much time to study the classics?""That is so.""Pity. Pity. You've missed a lot. Everyone should be made to study the classics, if I had my way."Poirot shrugged his shoulders."Eh bien, I have got on very well without them.""Got on! Got on? It's not a question of getting on. That's the wrong view all together. The classics aren't a ladder leading to quick success, like a modern correspondence course! It's not a man's working hours that are important--it's his leisure hours. That's the mistake we all make. Take yourself now, you're getting on, you'll be wanting to get out of things, to take things easy--what are you going to do then with your leisure hours?”

“There is too much tendency to attribute to God the evils that man does of his own free will. I must concede you the Devil. God doesn't really need to punish us, Miss Barton. We're so busy punishing ourselves.”

“Nothing is so sad, in my opinion, as the devastation wrought by age. My poor friend. I have described him many times. Now to convey to you the difference. Crippled with arthritis, he propelled himself about in a wheelchair. His once plump frame had fallen in. He was a thin little man now. His face was lined and wrinkled. His moustache and hair, and hair, it is true, were still of a jet black colour, but candidly, though I would not for the world have hurt his feelings by saying so to him, this was a mistake. There comes a moment when hair dye is only too painfully obvious. There had been a time when I had been surprised to learn that the blackness of Poirot's hair came out of a bottle. But now the theatricality was apparent and merely created the impression that he wore a wig and had adorned his upper lip to amuse children!”

“It was An­tho­ny Marston who dis­agreed with the ma­jor­ity. 'A bit un­sport­ing, what?' he said. 'Ought to fer­ret out the mys­tery be­fore we go. Whole thing's like a de­tec­tive sto­ry. Pos­itive­ly thrilling.' The judge said acid­ly: 'At my time of life, I have no de­sire for "thrills," as you call them.' An­tho­ny said with a grin: 'The le­gal life's narrow­ing! I'm all for crime! Here's to it.' He picked up his drink and drank it off at a gulp. Too quick­ly, per­haps. He choked -​ choked bad­ly. His face contort­ed, turned pur­ple. He gasped for breath -​ then slid down off his chair, the glass falling from his hand.”
