"There were so many strangers about, Lady Clarke. It is the holiday season."

"Yes—I forgot . . . . But they keep down by the beaches, they don't come up near the house."

"No stranger came to the house that day."

"Who says so?" demanded Lady Clarke, with a sudden vigour.

Poirot looked slightly taken aback. "The servants," he said. "Miss Grey."

Lady Clarke said very distinctly: "That girl is a liar!"

I started on my chair. Poirot threw me a glance.

Lady Clarke was going on, speaking now rather feverishly. "I didn't like her. I never liked her. Car thought all the world of her. Used to go on about her being an orphan and alone in the world. What's wrong with being an orphan? Sometimes it's a blessing in disguise. You might have a good-for-nothing father and a mother who drank—then you would have something to complain about. Said she was so brave and such a good worker. I dare say she did her work well! I don't know where all this bravery came in!"

"Now don't excite yourself, dear," said Nurse Capstick, intervening. "We mustn't have you getting tired."

"I soon sent her packing! Franklin had the impertinence to suggest that she might be a comfort to me. Comfort to me indeed! The sooner I saw the last of her the better—that's what I said! Franklin's a fool! I didn't want him getting mixed up with her. He's a boy! No sense! 'I'll give her three months' salary, if you like,' I said. 'But out she goes. I don't want her in the house a day longer.' There's one thing about being ill—men can't argue with you. He did what I said and she went."

"Went like a martyr, I expect—with more sweetness and bravery!"

"Now, dear, don't get so excited. It's bad for you."

Lady Clarke waved Nurse Capstick away. "You were as much of a fool about her as anyone else."

"Oh! Lady Clarke, you mustn't say that. I did think Miss Grey a very nice girl—so romantic-looking, like someone out of a novel."

"I've no patience with the lot of you," said Lady Clarke feebly.

"Well, she's gone now, my dear. Gone right away."

Lady Clarke shook her head with feeble impatience but she did not answer.

Poirot said: "Why did you say that Miss Grey was a liar?"

"Because she is. She told you no strangers came to the house, didn't she?"

"Yes."

"Very well, then. I saw her—with my own eyes—out of this window—talking to a perfectly strange man on the front door step."

"When was this?"

"In the morning of the day Car died—about eleven o'clock."

"What did this man look like?"

"An ordinary sort of man. Nothing special."

"A gentleman—or a tradesman?"

"Not a tradesman. A shabby sort of person. I can't remember." A sudden quiver of pain shot across her face.

"Please—you must go now—I'm a little tired. Nurse."

We obeyed the cue and took our departure.

"That's an extraordinary story," I said to Poirot as we journeyed back to London. "About Miss Grey and a strange man."

"You see, Hastings? It is, as I tell you: there is always something to be found out."

"Why did the girl lie about it and say she had seen no one?"

"I can think of seven separate reasons—one of them an extremely simple one."

"Is that a snub?" I asked.

"It is, perhaps, an invitation to use your ingenuity. But there is no need for us to perturb ourselves. The easiest way to answer the question is to ask her."

"And suppose she tells us another lie."

"That would indeed be interesting—and highly suggestive."

"It is monstrous to suppose that a girl like that could be in league with a madman."

"Precisely—so I do not suppose it."

I thought for some minutes longer. "A good-looking girl has a hard time of it," I said at last with a sigh.

"Du tout. Disabuse your mind of that idea."

"It's true," I insisted. "Everyone's hand is against her simply because she is good-looking."

"You speak the [unclear], my friend. Whose hand was against her at Combeside? Sir Carmichael's? Franklin's? Nurse Capstick's?"

"Lady Clarke was down on her, all right."

"Mon ami, you are full of charitable feeling towards beautiful young girls. Me, I feel charitable to sick old ladies. It may be that Lady Clarke was the clear-sighted one—and that her husband, Mr. Franklin Clarke and Nurse Capstick were all as blind as bats—and Captain Hastings."

"Realize, Hastings, that in the ordinary course of events those three separate dramas would never have touched each other. They would have pursued their course uninfluenced by each other. The permutations and combinations of life, Hastings—I never cease to be fascinated by them."

"This is Paddington," was the only answer I made.

It was time, I felt, that someone pricked the bubble.

On our arrival at Whitehaven Mansions we were told a gentleman was waiting to see Poirot.

I expected it to be Franklin, or perhaps Japp, but to my astonishment it turned out to be none other than Donald Fraser.

He seemed very embarrassed and his inarticulateness was more noticeable than ever.

Poirot did not press him to come to the point of his visit, but instead suggested sandwiches and a glass of wine.

Until these made their appearance he monopolized the conversation, explaining where we had been, and speaking with kindliness and feeling of the invalid woman.

Not until we finished the sandwiches and sipped the wine did he give the conversation a personal turn.

"You have come from Bexhill, Mr. Fraser?"

"Yes."

"Any success with Milly Higley?"

"Milly Higley? Milly Higley?" Fraser repeated the name wonderingly. "Oh, that girl! No, I haven't done anything there yet. It's—"

He stopped. His hands twisted themselves together nervously. "I don't know why I've come to you," he burst out.

"I know," said Poirot.

"You can't. How can you?"

"You have come to me because there is something that you must tell to someone. You were quite right. I am the proper person. Speak!"

Poirot's air of assurance had its effect. Fraser looked at him with a queer air of grateful obedience.

"You think so?"

"Parbleu, I am sure of it."

"M. Poirot, do you know anything about dreams?"

It was the last thing I had expected him to say. Poirot, however, seemed in no wise surprised.

"I do," he replied. "You have been dreaming—?"

"Yes. I suppose you'll say it's only natural that I should—should dream about it. But it isn't an ordinary dream."

"No?"

"I've dreamed it now three nights running, sir . . . . I think I'm going mad . . . ."

"Tell me—"

The man's face was livid. His eyes were starting out of his head. As a matter of fact, he looked mad.

"It's always the same. I'm on the beach. Looking for Betty. She's lost—only lost, you understand. I've got to find her. I've got to give her her belt. I'm carrying it in my hand. And then—"

"Yes?"

"The dream changes . . . I'm not looking anymore. She's there in front of me—sitting on the beach. She doesn't see me coming— Oh—oh, I can't—"

"Go on." Poirot's voice was authoritative—firm.

"I come up behind her . . . she doesn't hear me . . . I slip the belt around her neck and pull—oh—pull—"
