“About Miss Debenham," he said rather awkwardly. "You can take it from me that she's all right. She's a pukka sahib."What," asked Dr. Constantine with interest, "does a pukka sahib mean?""It means," said Poirot, "that Miss Debenham's father and brothers were at the same kind of school as Colonel Arbuthnot was.""Oh!" said Dr. Constantine, disappointed. "Then it has nothing to do with the crime at all.""Exactly," said Poirot.”

“Poirot's eyes opened. "That is great ferocity," he said."It is a woman," said the chef de train, speaking for the first time. "Depend upon it, it was a woman. Only a woman would stab like that."Dr. Constantine screwed up his face thoughtfully. "She must have been a very strong woman," he said. "It is not my desire to speak technically-that is only confusing; but I can assure you that two of the blows were delivered with such forces as to drive them through hard belts of bone and muscle.""It was clearly not a scientific crime," said Poirot."It was most unscientific," returned Dr. Constantine."The blows seem to have been delivered haphazard and at random. Some have glanced off, doing hardly any damage. It is as though somebody had shut his eyes and then in a frenzy struck blindly again and again.""C'est une femme," said the chef de train again. "Women are like that. When they are enraged they have great strength." He nodded so sagely that everyone suspected a personal experience of his own.”

“And Miss Ophelia?" he asked, getting round to her at last. "Miss Ophelia? Well, to tell you the truth, Ned, we're all rather worried about her." Ned recoiled as if a wasp had gone up his nose. "Oh? What's the trouble? Nothing serious, I hope." "She's gone all green," I said. "I think it's chlorosis. Dr. Darby thinks so too.”

“Oh, it's lovely to see you!' Franny said as the cab moved off. 'I've missed you.' The words were no sooner out than she realized that she didn't mean them at all.”

“As you yourself have said, what other explanation can there be?'Poirot stared straight ahead of him. 'That is what I ask myself,' he said. 'That is what I never cease to ask myself.”

“I could spank Constantine and skin him alive afterwards, that I could," she exclaimed bitterly. "Oh, Susan, I'm surprised at you," said the doctor, pulling a long face. "Have you no regard for the proprieties? Skin him alive by all means but omit the spanking.”
