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.

On Monday Poirot was out all day, but when he returned in the

evening he flung himself into his chair with a sigh of satisfaction.

“Hastings, shall I recount to you a little history? A story after

your own heart and which will remind you of your favourite cinema?”

“Go ahead,” I laughed. “I presume that it is a true story, not one

of your efforts of fancy.”

“It is true enough. Inspector Japp of Scotland Yard will vouch for

its accuracy, since it was through his kind offices that it came

to my ears. Listen, Hastings. A little over six months ago some

important Naval plans were stolen from an American Government

department. They showed the position of some of the most important

Harbour defences, and would be worth a considerable sum to any

foreign Government—that of Japan, for example. Suspicion fell upon

a young man named Luigi Valdarno, an Italian by birth, who was

employed in a minor capacity in the Department and who was missing

at the same time as the papers. Whether Luigi Valdarno was the

thief or not, he was found two days later on the East Side in New

York, shot dead. The papers were not on him. Now for some time past

Luigi Valdarno had been going about with a Miss Elsa Hardt, a young

concert singer who had recently appeared and who lived with a

brother in an apartment in Washington. Nothing was known of the

antecedents of Miss Elsa Hardt, and she disappeared suddenly about

the time of Valdarno’s death. There are reasons for believing that

she was in reality an accomplished international spy who has done

much nefarious work under various _aliases_. The American Secret

Service, whilst doing their best to trace her, also kept an eye

upon certain insignificant Japanese gentlemen living in Washington.

They felt pretty certain that, when Elsa Hardt had covered her

tracks sufficiently, she would approach the gentlemen in question.

One of them left suddenly for England a fortnight ago. On the face

of it, therefore, it would seem that Elsa Hardt is in England.”

Poirot paused, and then added softly: “The official description of

Elsa Hardt is: Height 5 ft. 7, eyes blue, hair auburn, fair

complexion, nose straight, no special distinguishing marks.”

“Mrs. Robinson!” I gasped.

“Well, there is a chance of it, anyhow,” amended Poirot. “Also, I

learn that a swarthy man, a foreigner of some kind, was inquiring

about the occupants of No. 4 only this morning. Therefore, _mon

ami_, I fear that you must forswear your beauty sleep to-night,

and join me in my all-night vigil in the flat below—armed with that

excellent revolver of yours, _bien entendu_!”

“Rather,” I cried with enthusiasm. “When shall we start?”

“The hour of midnight is both solemn and suitable, I fancy. Nothing

is likely to occur before then.”

At twelve o’clock precisely, we crept cautiously into the coal-lift

and lowered ourselves to the second floor. Under Poirot’s

manipulation, the wooden door quickly swung inwards, and we climbed

into the flat. From the scullery we passed into the kitchen where

we established ourselves comfortably in two chairs with the door

into the hall ajar.

“Now we have but to wait,” said Poirot contentedly, closing his

eyes.

To me, the waiting appeared endless. I was terrified of going to

sleep. Just when it seemed to me that I had been there about eight

hours—and had, as I found out afterwards, in reality been exactly

one hour and twenty minutes—a faint scratching sound came to my

ears. Poirot’s hand touched mine. I rose, and together we moved

carefully in the direction of the hall. The noise came from there.

Poirot placed his lips to my ear.

“Outside the front door. They are cutting out the lock. When I give

the word, not before, fall upon him from behind and hold him fast.

Be careful, he will have a knife.”

Presently there was a rending sound, and a little circle of light

appeared through the door. It was extinguished immediately and then

the door was slowly opened. Poirot and I flattened ourselves

against the wall. I heard a man’s breathing as he passed us. Then

he flashed on his torch, and as he did so, Poirot hissed in my ear:

“_Allez_.”

We sprang together, Poirot with a quick movement enveloped the

intruder’s head with a light woollen scarf whilst I pinioned his

arms. The whole affair was quick and noiseless. I twisted a dagger

from his hand, and as Poirot brought down the scarf from his eyes,

whilst keeping it wound tightly round his mouth, I jerked up my

revolver where he could see it and understand that resistance was

useless. As he ceased to struggle Poirot put his mouth close to

his ear and began to whisper rapidly. After a minute the man

nodded. Then enjoining silence with a movement of the hand, Poirot

led the way out of the flat and down the stairs. Our captive

followed, and I brought up the rear with the revolver. When we were

out in the street, Poirot turned to me.

“There is a taxi waiting just round the corner. Give me the

revolver. We shall not need it now.”

“But if this fellow tries to escape?”

Poirot smiled.

“He will not.”

I returned in a minute with the waiting taxi. The scarf had been

unwound from the stranger’s face, and I gave a start of surprise.

“He’s not a Jap,” I ejaculated in a whisper to Poirot.

“Observation was always your strong point, Hastings! Nothing

escapes you. No, the man is not a Jap. He is an Italian.”

We got into the taxi, and Poirot gave the driver an address in St.

John’s Wood. I was by now completely fogged. I did not like to ask

Poirot where we were going in front of our captive, and strove in

vain to obtain some light upon the proceedings.

We alighted at the door of a small house standing back from the

road. A returning wayfarer, slightly drunk, was lurching along the

pavement and almost collided with Poirot, who said something

sharply to him which I did not catch. All three of us went up the

steps of the house. Poirot rang the bell and motioned us to stand

a little aside. There was no answer and he rang again and then

seized the knocker which he plied for some minutes vigorously.

A light appeared suddenly above the fanlight, and the door was

opened cautiously a little way.

“What the devil do you want?” a man’s voice demanded harshly.

“I want the doctor. My wife is taken ill.”

“There’s no doctor here.”

The man prepared to shut the door, but Poirot thrust his foot in

adroitly. He became suddenly a perfect caricature of an infuriated

Frenchman.

“What you say, there is no doctor? I will have the law of you. You

must come! I will stay here and ring and knock all night.”

“My dear sir——” The door was opened again, the man, clad in a

dressing-gown and slippers, stepped forward to pacify Poirot with

an uneasy glance round.

“I will call the police.”

Poirot prepared to descend the steps.

“No, don’t do that for Heaven’s sake!” The man dashed after him.

With a neat push Poirot sent him staggering down the steps. In

another minute all three of us were inside the door and it was

pushed to and bolted.

“Quick—in here.” Poirot led the way into the nearest room switching

on the light as he did so. “And you—behind the curtain.”

“Si, signor,” said the Italian and slid rapidly behind the full

folds of rose-coloured velvet which draped the embrasure of the

window.

Not a minute too soon. Just as he disappeared from view a woman

rushed into the room. She was tall with reddish hair and held a

scarlet kimono round her slender form.

“Where is my husband?” she cried, with a quick frightened glance.

“Who are you?”

Poirot stepped forward with a bow.

“It is to be hoped your husband will not suffer from a chill. I

observed that he had slippers on his feet, and that his dressing-gown

was a warm one.”

“Who are you? What are you doing in my house?”

“It is true that none of us have the pleasure of your acquaintance,

madame. It is especially to be regretted as one of our number has

come specially from New York in order to meet you.”

The curtains parted and the Italian stepped out. To my horror I

observed that he was brandishing my revolver, which Poirot must

doubtless have put down through inadvertence in the cab.

The woman gave a piercing scream and turned to fly, but Poirot was

standing in front of the closed door.

“Let me by,” she shrieked. “He will murder me.”

“Who was it dat croaked Luigi Valdarno?” asked the Italian hoarsely,

brandishing the weapon, and sweeping each one of us with it. We

dared not move.

“My God, Poirot, this is awful. What shall we do?” I cried.

“You will oblige me by refraining from talking so much, Hastings.

I can assure you that our friend will not shoot until I give the

word.”

“Youse sure o’ dat, eh?” said the Italian, leering unpleasantly.

It was more than I was, but the woman turned to Poirot like a

flash.

“What is it you want?”

Poirot bowed.

“I do not think it is necessary to insult Miss Elsa Hardt’s

intelligence by telling her.”

With a swift movement, the woman snatched up a big black velvet

cat which served as a cover for the telephone.

“They are stitched in the lining of that.”

“Clever,” murmured Poirot appreciatively. He stood aside from the

door. “Good evening, madame. I will detain your friend from New

York whilst you make your getaway.”

“Whatta fool!” roared the big Italian, and raising the revolver he

fired point-blank at the woman’s retreating figure just as I flung

myself upon him.

But the weapon merely clicked harmlessly and Poirot’s voice rose

in mild reproof.

“Never will you trust your old friend, Hastings. I do not care for

my friends to carry loaded pistols about with them and never would

I permit a mere acquaintance to do so. No, no, _mon ami_.” This to

the Italian who swearing hoarsely. Poirot continued to address him

in a tone of mild reproof: “See now, what I have done for you. I

have saved you from being hanged. And do not think that our

beautiful lady will escape. No, no, the house is watched, back and

front. Straight into the arms of the police they will go. Is not

that a beautiful and consoling thought? Yes, you may leave the room

now. But be careful—be very careful. I——Ah, he is gone! And my

friend Hastings looks at me with eyes of reproach. But it was all

so simple! It was clear, from the first, that out of several

hundred, probably, applicants for No. 4, Montagu Mansions only the

Robinsons were considered suitable. Why? What was there that

singled them out from the rest—at practically a glance. Their

appearance? Possibly, but it was not so unusual. Their name, then!”

“But there’s nothing unusual about the name of Robinson,” I cried.

“It’s quite a common name.”

“Ah! _Sapristi_, but exactly! That was the point. Elsa Hardt and

her husband, or brother or whatever he really is, come from New

York, and take a flat in the name of Mr. and Mrs. Robinson. Suddenly

they learn that one of these secret societies, the Mafia, or the

Camorra, to which doubtless Luigi Valdarno belonged, is on their

track. What do they do? They hit on a scheme of transparent

simplicity. Evidently they knew that their pursuers were not

personally acquainted with either of them. What then can be simpler?

They offer the flat at an absurdly low rental. Of the thousands of

young couples in London looking for flats, there cannot fail to be

several Robinsons. It is only a matter of waiting. If you will look

at the name of Robinson in the telephone directory, you will

realize that a fair-haired Mrs. Robinson was pretty sure to come

along sooner or later. Then what will happen? The avenger arrives.

He knows the name, he knows the address. He strikes! All is over,

vengeance is satisfied, and Miss Elsa Hardt has escaped by the skin

of her teeth once more. By the way, Hastings, you must present me

to the real Mrs. Robinson—that delightful and truthful creature!

What will they think when they find their flat has been broken

into! We must hurry back. Ah, that sounds like Japp and his friends

arriving.”

A mighty tattoo sounded on the knocker.

“How did you know this address?” I asked as I followed Poirot out

into the hall. “Oh, of course, you had the first Mrs. Robinson

followed when she left the other flat.”

“_A la bonne heure_, Hastings. You use your grey cells at last.

Now for a little surprise for Japp.”

Softly unbolting the door, he stuck the cat’s head round the edge

and ejaculated a piercing “Miaow.”

The Scotland Yard inspector, who was standing outside with another

man, jumped in spite of himself.

“Oh, it’s only Monsieur Poirot at one of his little jokes!” he

exclaimed, as Poirot’s head followed that of the cat. “Let us in,

moosior.”

“You have our friends safe and sound?”

“Yes, we’ve got the birds all right. But they hadn’t got the goods

with them.”

“I see. So you come to search. Well, I am about to depart with

Hastings, but I should like to give you a little lecture upon the

history and habits of the domestic cat.”

“For the Lord’s sake, have you gone completely balmy?”

“The cat,” declaimed Poirot, “was worshipped by the ancient

Egyptians. It is still regarded as a symbol of good luck if a black

cat crosses your path. This cat crossed your path to-night, Japp.

To speak of the interior of any animal or any person is not, I

know, considered polite in England. But the interior of this cat

is perfectly delicate. I refer to the lining.”

With a sudden grunt, the second man seized the cat from Poirot’s

hand.

“Oh, I forgot to introduce you,” said Japp. “Mr. Poirot, this is

Mr. Burt of the United States Secret Service.”

The American’s trained fingers had felt what he was looking for.

He held out his hand, and for a moment speech failed him. Then he

rose to the occasion.

“Pleased to meet you,” said Mr. Burt.
