Hercule Poirot: [voice-over] It was quite immaterial. I take the sleeping tablets and have acquired a certain tolerance. The dose that would send Norton to sleep would have little effect on me. With the greatest of difficulty, I put him in my wheelchair, then, when the coast was clear, I wheeled him to his room. You will not have realized, Hastings, that recently I have taken to wearing a false moustache. Even George does not know that.
Hercule Poirot: [flashback, showing Poirot in Norton's room, removing his false moustache] I put on the dressing gown of Norton, tapped on your door, then went into his bathroom. Presently, I heard you open your door. I left the bathroom and returned into the room of Norton, locking the door behind me.
Hercule Poirot: [struggling to lay Norton on his bed] I put the dressing gown on Norton, and lay him on his bed. I had a pistol, which on two occasions I had placed ostentatiously on the dressing table of Norton when he was out, so that the maid would have seen it.
Hercule Poirot: [puts the pistol to Norton's head as he awakens, smiling... then fires] I put the key into the pocket of his dressing gown and locked the door from the outside with a duplicate I had made, then returned to my room and began writing this. I played the game, as you English say. I gave to you the clues and every chance to discover the truth, pointing you towards Iago, the original Stephen Norton. My only weakness was to shoot him in the center of his forehead and not in his temple, but I could not bring myself to produce an effect so lopsided. That, mon ami, is my nature, and should have told to you the truth.
Hercule Poirot: [voice-over as Hastings speaks with Miss Cole] Take my advice for the last time. Tell to Mademoiselle Cole all that I have said, that you also might have done what her sister did, had there been no watchful Poirot to stop you. Take the nightmare away, and show how Norton, not her sister, was responsible for the death of her father.
Hercule Poirot: [flashback to Styles, as Hastings discovers Poirot dead in his room] I have no more to say. Am I justified in what I have done? I do not know. I do not believe that a man should take the law into his own hands... but by taking the life of Norton, have I not saved others? I have always been so sure, but now...
Hercule Poirot: [flashback, Poirot writing the confession, kissing his rosary] When the moment comes, I will not try to save myself, but humbly offer my soul to God and pray for His mercy. It is for Him to decide. Ah, Hastings, my dear friend. They were good days. Yes... they have been good days.
