Miss Brewster shrugged her shoulders.
“Oh! of course I realize that, but all the same—”
“But all the same this still seems to you an unlikely setting for crime? You forget one thing, Mademoiselle.”
“Human nature, I suppose?”
“That, yes. That, always. But that was not what I was going to say. I was going to point out to you that here everyone is on holiday.”
Emily Brewster turned a puzzled face to him.
“I don’t understand.”
Hercule Poirot beamed kindly at her. He made dabs in the air with an emphatic forefinger.
“Let us say, you have an enemy. If you seek him out in his flat, in his office, in the street—eh bien, you must have a reason—you must account for yourself. But here at the seaside it is necessary for no one to account for himself. You are at Leathercombe Bay, why? Parbleu! it is August—one goes to the seaside in August—one is on one’s holiday. It is quite natural, you see, for you to be here and for Mr. Lane to be here and for Major Barry to be here and for Mrs. Redfern and her husband to be here. Because it is the custom in England to go to the seaside in August.”
“Well,” admitted Miss Brewster, “that’s certainly a very ingenious idea. But what about the Gardeners? They’re American.”
Poirot smiled.
“Even Mrs. Gardener, as she told us, feels the need to relax. Also, since she is ‘doing’ England, she must certainly spend a fortnight at the seaside—as a good tourist, if nothing else. She enjoys watching people.”
Mrs. Redfern murmured:
“You like watching the people too, I think?”
“Madame, I will confess it. I do.”
She said thoughtfully: “You see—a good deal.”

There was a pause. Stephen Lane cleared his throat and said with a trace of self-consciousness.
“I was interested, M. Poirot, in something you said just now. You said that there was evil done everywhere under the sun. It was almost a quotation from Ecclesiastes.” He paused and then quoted himself: “Yea, also the heart of the sons of men is full of evil, and madness is in their heart while they live.” His face lit up with an almost fanatical light. “I was glad to hear you say that. Nowadays, no one believes in evil. It is considered, at most, a mere negation of good. Evil, people say, is done by those who know no better—who are undeveloped—who are to be pitied rather than blamed. But M. Poirot, evil is real! It is a fact! I believe in Evil like I believe in Good. It exists! It is powerful! It walks the earth!”
He stopped. His breath was coming fast. He wiped his forehead with his handkerchief and looked suddenly apologetic.
“I’m sorry. I got carried away.”
Poirot said calmly:
“I understand your meaning. Up to a point I agree with you. Evil does walk the earth and can be recognized as such.”
Major Barry cleared his throat.
“Talking of that sort of thing, some of these fakir fellers in India—”
Major Barry had been long enough at the Jolly Roger for everyone to be on their guard against his fatal tendency to embark on long Indian stories. Both Miss Brewster and Mrs. Redfern burst into speech.
“That’s your husband swimming in now, isn’t it, Mrs. Redfern? How magnificent his crawl stroke is. He’s an awfully good swimmer.”
At the same moment Mrs. Redfern said:
“Oh look! What a lovely little boat that is out there with the red sails. It’s Mr. Blatt’s, isn’t it?”
The sailing boat with the red sails was just crossing the end of the bay.
