The reply to Armstrong, from Hercule Poirot
My dear Colonel Armstrong. Finally, I can answer your letter. At least with the thoughts in my head and the feeling in my heart… that somewhere,you can hear me. I have now discovered the truth of the case, and it is profoundly disturbing. I have seen the fracture of the human soul. So many broken lives, so much pain and anger giving way to the poison of deep grief until one crime became many. I have always wanted to believe that man is rational and civilized. My very existence depends upon this hope upon order and method and the little gray cells. But now, perhaps, I am asked to listen instead to my heart.
The last words to the murders from Hercule Poirot
Ladies and gentlemen, I have understood in this case that the scales of justice cannot always be evenly weighed. And I must learn, for once to live with the imbalance. There are no killers here. Only people who deserve a chance to heal. The police have accepted my first solution to the crime the lone assassin who made his escape. I will leave the train hereto conclude formalities. You are all free to go. And may you find your peace with this. May we all.
