“I was thinking, that when my time comes, I should be sorry if the only plea I had to offer was that of justice. Because it might mean that only justice would be meted out to me.”

“If I were at any time to set out on a career of deceit, it would be of Miss Marple that I should be afraid.”

“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 clumsy, all the same - for I had no suspicion - at least hardly any suspicion. Yes, but for my quick eyes, the eyes of a cat, Hercule Poirot might now be crushed out of existence - a terrible calamity for the world. And you, too, mon ami - though that would not be such a national catastrophe." "Thank you," I said coldly.”

“Plots come to me at such odd moments, when I am walking along the street, or examining a hat shop…suddenly a splendid idea comes into my head.”
