So far, in the cases which I have recorded, Poirot’s investigations have started from the central fact, whether murder or robbery, and have proceeded from thence by a process of logical deduction to the final triumphant unravelling. In the events I am now about to chronicle, a remarkable chain of circumstances led from the apparently trivial incidents which first attracted Poirot’s attention to the sinister happenings which completed a most unusual case.

I had been spending the evening with an old friend of mine, Gerald Parker. There had been, perhaps, about half a dozen people there besides my host and myself, and the talk fell, as it was bound to do sooner or later wherever Parker found himself, on the subject of house-hunting in London. Houses and flats were Parker’s special hobby. Since the end of the War, he had occupied at least half a dozen different flats and maisonnettes. No sooner was he settled anywhere than he would light unexpectedly upon a new find, and would forthwith depart bag and baggage. His moves were nearly always accomplished at a slight pecuniary gain, for he had a shrewd business head, but it was sheer love of the sport that actuated him, and not a desire to make money at it. We listened to Parker for some time with the respect of the novice for the expert. Then it was our turn, and a perfect babel of tongues was let loose. Finally the floor was left to Mrs. Robinson, a charming little bride who was there with her husband. I had never met them before, as Robinson was only a recent acquaintance of Parker’s.

“Talking of flats,” she said, “have you heard of our piece of luck, Mr. Parker? We’ve got a flat — at last! In Montagu Mansions.”
“Well,” said Parker, “I’ve always said there are plenty of flats — at a price!”
“Yes, but this isn’t at a price. It’s dirt cheap. Eighty pounds a year!”

“But — but Montagu Mansions is just off Knightsbridge, isn’t it? Big handsome building. Or are you talking of a poor relation of the same name stuck in the slums somewhere?”
“No, it’s the Knightsbridge one. That’s what makes it so wonderful.”

“Wonderful is the word! It’s a blinking miracle. But there must be a catch somewhere. Big premium, I suppose?”
“No premium!”
“No prem — oh, hold my head, somebody!” groaned Parker.

“But we’ve got to buy the furniture,” continued Mrs. Robinson.
“Ah!” Parker brisked up. “I knew there was a catch!”
“For fifty pounds. And it’s beautifully furnished!”
“I give it up,” said Parker. “The present occupants must be lunatics with a taste for philanthropy.”

Mrs. Robinson was looking a little troubled. A little pucker appeared between her dainty brows.

“It is queer, isn’t it? You don’t think that — that — the place is haunted?”
“Never heard of a haunted flat,” declared Parker decisively.
“No.” Mrs. Robinson appeared far from convinced. “But there were several things about it all that struck me as — well, queer.”

“For instance — ” I suggested.

“Ah,” said Parker, “our criminal expert’s attention is aroused! Unburden yourself to him, Mrs. Robinson. Hastings is a great unraveller of mysteries.”

I laughed, embarrassed but not wholly displeased with the role thrust upon me.

“Oh, not really queer, Captain Hastings, but when we went to the agents, Stosser and Paul — we hadn’t tried them before because they only have the expensive Mayfair flats, but we thought at any rate it would do no harm — everything they offered us was four and five hundred a year, or else huge premiums, and then, just as we were going, they mentioned that they had a flat at eighty, but that they doubted if it would be any good our going there, because it had been on their books some time and they had sent so many people to see it that it was almost sure to be taken — ‘snapped up’ as the clerk put it — only people were so tiresome in not letting them know, and then they went on sending, and people get annoyed at being sent to a place that had, perhaps, been let some time.”

Mrs. Robinson paused for some much needed breath, and then continued: “We thanked him, and said that we quite understood it would probably be no good, but that we should like an order all the same — just in case. And we went there straight away in a taxi, for, after all, you never know. No. 4 was on the second floor, and just as we were waiting for the lift, Elsie Ferguson — she’s a friend of mine, Captain Hastings, and they are looking for a flat too — came hurrying down the stairs. ‘Ahead of you for once, my dear,’ she said. ‘But it’s no good. It’s already let.’ That seemed to finish it, but — well, as John said, the place was very cheap, we could afford to give more, and perhaps if we offered a premium. — A horrid thing to do, of course, and I feel quite ashamed of telling you, but you know what flat-hunting is.”

I assured her that I was well aware that in the struggle for house-room the baser side of human nature frequently triumphed over the higher, and that the well-known rule of dog eat dog always applied.

“So we went up and, would you believe it, the flat wasn’t let at all. We were shown over it by the maid, and then we saw the mistress, and the thing was settled then and there. Immediate possession and fifty pounds for the furniture. We signed the agreement next day, and we are to move in to-morrow!” Mrs. Robinson paused triumphantly.

“And what about Mrs. Ferguson?” asked Parker. “Let’s have your deductions, Hastings.”
“‘Obvious, my dear Watson,’” I quoted lightly. “She went to the wrong flat.”
“Oh, Captain Hastings, how clever of you!” cried Mrs. Robinson admiringly.

I rather wished Poirot had been there. Sometimes I have the feeling that he rather underestimates my capabilities.

The whole thing was rather amusing, and I propounded the thing as a mock problem to Poirot on the following morning. He seemed interested, and questioned me rather narrowly as to the rents of flats in various localities.

“A curious story,” he said thoughtfully. “Excuse me, Hastings, I must take a short stroll.”

When he returned, about an hour later, his eyes were gleaming with a peculiar excitement. He laid his stick on the table, and brushed the nap of his hat with his usual tender care before he spoke.

“It is as well, mon ami, that we have no affairs of moment on hand. We can devote ourselves wholly to the present investigation.”
“What investigation are you talking about?”
“The remarkable cheapness of your friend’s, Mrs. Robinson’s, new flat.”

“Poirot, you are not serious!”
“I am most serious. Figure to yourself, my friend, that the real rent of those flats is £350. I have just ascertained that from the landlord’s agents. And yet this particular flat is being sublet at eighty pounds! Why?”

“There must be something wrong with it. Perhaps it is haunted, as Mrs. Robinson suggested.”

Poirot shook his head in a dissatisfied manner. “Then again how curious it is that her friend tells her the flat is let, and, when she goes up, behold, it is not so at all!”
“But surely you agree with me that the other woman must have gone to the wrong flat. That is the only possible solution.”

“You may or may not be right on that point, Hastings. The fact still remains that numerous other applicants were sent to see it, and yet, in spite of its remarkable cheapness, it was still in the market when Mrs. Robinson arrived.” “That shows that there must be something wrong about it.”
“Mrs. Robinson did not seem to notice anything amiss. Very curious, is it not? Did she impress you as being a truthful woman, Hastings?”
“She was a delightful creature!”
“Évidemment! Since she renders you incapable of replying to my question. Describe her to me, then.”
“Well, she’s tall and fair; her hair’s really a beautiful shade of auburn — ”

“Always you have had a penchant for auburn hair!” murmured Poirot. “But continue.”

“Blue eyes and a very nice complexion and — well, that’s all, I think,” I concluded lamely.
“And her husband?”
“Oh, he’s quite a nice fellow — nothing startling.”
“Dark or fair?”
“I don’t know — betwixt and between, and just an ordinary sort of face.”

Poirot nodded. “Yes, there are hundreds of these average men — and, anyway, you bring more sympathy and appreciation to your description of women. Do you know anything about these people? Does Parker know them well.”
“They are just recent acquaintances, I believe. But surely, Poirot, you don’t think for an instant — ”

Poirot raised his hand. “Tout doucement, mon ami. Have I said that I think anything? All I say is — it is a curious story. And there is nothing to throw light upon it; except perhaps the lady’s name, eh, Hastings?”

“Her name is Stella,” I said stiffly, “but I don’t see — ”

Poirot interrupted me with a tremendous chuckle. Something seemed to be amusing him vastly. “And Stella means a star, does it not? Famous!”
“What on earth — ”
“And stars give light! Voilà! Calm yourself, Hastings. Do not put on that air of injured dignity. Come, we will go to Montagu Mansions and make a few inquiries.”

I accompanied him, nothing loath. The Mansions were a handsome block of buildings in excellent repair. A uniformed porter was sunning himself on the threshold, and it was to him that Poirot addressed himself:
“Pardon, but could you tell me if a Mr. and Mrs. Robinson reside here?”

The porter was a man of few words and apparently of a sour or suspicious disposition. He hardly looked at us and grunted out: “No. 4. Second floor.”
“I thank you. Can you tell me how long they have been here?”
“Six months.”

I started forward in amazement, conscious as I did so of Poirot’s malicious grin.
“Impossible,” I cried. “You must be making a mistake.”
“Six months.”

“Are you sure? The lady I mean is tall and fair with reddish gold hair and — ”
“That’s ’er,” said the porter. “Come in the Michaelmas quarter, they did. Just six months ago.”

He appeared to lose interest in us and retreated slowly up the hall. I followed Poirot outside.

“Eh bien, Hastings?” my friend demanded slyly. “Are you so sure now that delightful women always speak the truth?”

I did not reply.

Poirot had steered his way into Brompton Road before I asked him what he was going to do and where we were going.

“To the house agents, Hastings. I have a great desire to have a flat in Montagu Mansions. If I am not mistaken, several interesting things will take place there before long.”

We were fortunate in our quest. No. 8, on the fourth floor, was to be let furnished at ten guineas a week. Poirot promptly took it for a month.

Outside in the street again, he silenced my protests: “But I make money nowadays! Why should I not indulge a whim? By the way, Hastings, have you a revolver?”
“Yes — somewhere,” I answered, slightly thrilled. “Do you think — ”
“That you will need it? It is quite possible. The idea pleases you, I see. Always the spectacular and romantic appeals to you.”

The following day saw us installed in our temporary home. The flat was pleasantly furnished. It occupied the same position in the building as that of the Robinsons, but was two floors higher.

The day after our installation was a Sunday. In the afternoon, Poirot left the front door ajar, and summoned me hastily as a bang reverberated from somewhere below.
“Look over the banisters. Are those your friends. Do not let them see you.”

I craned my neck over the staircase.

“That’s them,” I declared in an ungrammatical whisper.
“Good. Wait awhile.”

About half an hour later, a young woman emerged in brilliant and varied clothing. With a sigh of satisfaction, Poirot tiptoed back into the flat.

“C’est ça. After the master and mistress, the maid. The flat should now be empty.”

“What are we going to do?” I asked uneasily.

Poirot had trotted briskly into the scullery and was hauling at the rope of the coal-lift.
“We are about to descend after the method of the dustbins,” he explained cheerfully. “No one will observe us. The Sunday concert, the Sunday ‘afternoon out,’ and finally the Sunday nap after the Sunday dinner of England — le rosbif — all these will distract attention from the doings of Hercule Poirot. Come, my friend.”

He stepped into the rough wooden contrivance and I followed him gingerly.

“Are we going to break into the flat?” I asked dubiously.
Poirot’s answer was not too reassuring: “Not precisely to-day,” he replied.

Pulling on the rope, we descended slowly till we reached the second floor. Poirot uttered an exclamation of satisfaction as he perceived that the wooden door into the scullery was open.

“You observe? Never do they bolt these doors in the daytime. And yet anyone could mount or descend as we have done. At night yes — though not always then — and it is against that that we are going to make provision.”

He had drawn some tools from his pocket as he spoke, and at once set deftly to work, his object being to arrange the bolt so that it could be pulled back from the lift. The operation only occupied about three minutes. Then Poirot returned the tools to his pocket, and we reascended once more to our own domain.
