Miss Martin went on:--

"Evidently about some property Mr. Ryland was thinking of buying. But

really, I do feel that a man who can get into a rage over such a trifle

is, well, dangerous. What do you think I ought to do, Major Neville?

You've more experience of the world than I have."

I soothed the girl down, pointed out to her that Mr. Ryland had

probably been suffering from the enemy of his race--dyspepsia. In

the end I sent her away quite comforted. But I was not so easily

satisfied myself. When the girl had gone, and I was alone, I took out

my notebook, and ran over the letter which I had jotted down. What did

it mean--this apparently innocent-sounding missive? Did it concern some

business deal which Ryland was undertaking, and was he anxious that no

details about it should leak out until it was carried through? That was

a possible explanation. But I remembered the small figure 4 with which

the envelopes were marked, and I felt that, at last, I was on the track

of the thing we were seeking.

I puzzled over the letter all that evening, and most of the next

day--and then suddenly the solution came to me. It was so simple, too.

The figure 4 was the clue. Read every fourth word in the letter, and an

entirely different message appeared. "Essential should see you quarry

seventeen eleven four."

The solution of the figures was easy. Seventeen stood for the

seventeenth of October--which was to-morrow, eleven was the time, and

four was the signature--either referring to the mysterious Number Four

himself--or else it was the "trade-mark" so to speak, of the Big Four.

The quarry was also intelligible. There was a big disused quarry on the

estate about half a mile from the house--a lonely spot, ideal for a

secret meeting.

For a moment or two I was tempted to run the show myself. It would be

such a feather in my cap, for once, to have the pleasure of crowing

over Poirot.

But in the end I overcame the temptation. This was a big business--I

had no right to play a lone hand, and perhaps jeopardise our chances of

success. For the first time, we had stolen a march upon our enemies. We

must make good this time--and, disguise the fact as I might, Poirot had

the better brain of the two.

I wrote off post haste to him, laying the facts before him, and

explaining how urgent it was that we should overhear what went on at

the interview. If he liked to leave it to me, well and good, but I gave

him detailed instructions how to reach the quarry from the station in

case he should deem it wise to be present himself.

I took the letter down to the village and posted it myself. I had been

able to communicate with Poirot throughout my stay, by the simple

expedient of posting my letters myself, but we had agreed that he

should not attempt to communicate with me in case my letters should be

tampered with.

I was in a glow of excitement the following evening. No guests were

staying in the house, and I was busy with Mr. Ryland in his study all

the evening. I had foreseen that this would be the case, which was why

I had had no hope of being able to meet Poirot at the station. I was,

however, confident that I would be dismissed well before eleven o'clock.

Sure enough, just after ten-thirty, Mr. Ryland glanced at the clock,

and announced that he was "through." I took the hint and retired

discreetly. I went upstairs as though going to bed, but slipped quietly

down a side staircase and let myself out into the garden, having taken

the precaution to don a dark overcoat to hide my white shirt-front.

I had gone some way down the garden when I chanced to look over my

shoulder. Mr. Ryland was just stepping out from his study window into

the garden. He was starting to keep the appointment. I redoubled my

pace, so as to get a clear start. I arrived at the quarry somewhat out

of breath. There seemed no one about, and I crawled into a thick tangle

of bushes and awaited developments.

Ten minutes later, just on the stroke of eleven, Ryland stalked up,

his hat over his eyes and the inevitable cigar in his mouth. He

gave a quick look round, and then plunged into the hollows of the

quarry below. Presently I heard a low murmur of voices come up to me.

Evidently the other man--or men--whoever they were, had arrived first

at the rendezvous. I crawled cautiously out of the bushes, and inch

by inch, using the utmost precaution against noise, I wormed myself

down the steep path. Only a boulder now separated me from the talking

men. Secure in the blackness, I peeped round the edge of it and found

myself facing the muzzle of a black, murderous-looking automatic!

"Hands up!" said Mr. Ryland succinctly. "I've been waiting for you."

He was seated in the shadow of the rock, so that I could not see his

face, but the menace in his voice was unpleasant. Then I felt a ring of

cold steel on the back of my neck, and Ryland lowered his own automatic.

"That's right, George," he drawled. "March him around here."

Raging inwardly, I was conducted to a spot in the shadows, where the

unseen George (whom I suspected of being the impeccable Deaves), gagged

and bound me securely.

Ryland spoke again in a tone which I had difficulty in recognising, so

cold and menacing was it.

"This is going to be the end of you two. You've got in the way of the

Big Four once too often. Ever heard of land slides? There was one about

here two years ago. There's going to be another to-night. I've fixed

that good and square. Say, that friend of yours doesn't keep his dates

very punctually."

A wave of horror swept over me. Poirot! In another minute he would

walk straight into the trap. And I was powerless to warn him. I could

only pray that he had elected to leave the matter in my hands, and had

remained in London. Surely, if he had been coming, he would have been

here by now.

With every minute that passed, my hopes rose.

Suddenly they were dashed to pieces. I heard footsteps--cautious

footsteps, but footsteps nevertheless. I writhed in impotent agony.

They came down the path, paused, and then Poirot himself appeared, his

head a little on one side, peering into the shadows.

I heard the growl of satisfaction Ryland gave as he raised the big

automatic and shouted "Hands up." Deaves sprang forward as he did so,

and took Poirot in the rear. The ambush was complete.

"Please to meet you, Mr. Hercule Poirot," said the American grimly.

Poirot's self-possession was marvellous. He did not turn a hair. But I

saw his eyes searching in the shadows.

"My friend? He is here?"

"Yes, you are both in the trap--the trap of the Big Four."

He laughed.

"A trap?" queried Poirot.

"Say, haven't you tumbled to it yet?"

"I comprehend that there is a trap--yes," said Poirot gently. "But you

are in error, monsieur. It is _you_ who are in it--not I and my

friend."

"What?" Ryland raised the big automatic, but I saw his gaze falter.

"If you fire, you commit murder watched by ten pairs of eyes, and you

will be hanged for it. This place is surrounded--has been for the last

hour--by Scotland Yard men. It is checkmate, Mr. Abe Ryland."

He uttered a curious whistle, and as though by magic, the place was

alive with men. They seized Ryland and the valet and disarmed them.

After speaking a few words to the officer in charge, Poirot took me by

the arm, and led me away.

Once clear of the quarry he embraced me with vigour.

"You are alive--you are unhurt. It is magnificent. Often have I blamed

myself for letting you go."

"I'm perfectly all right," I said, disengaging myself. "But I'm just a

bit fogged. You tumbled to their little scheme, did you?"

"But I was waiting for it! For what else did I permit you to go there?

Your false name, your disguise, not for a moment was it intended to

deceive!"

"What?" I cried. "You never told me."

"As I have frequently told you, Hastings, you have a nature so

beautiful and so honest that unless you are yourself deceived, it is

impossible for you to deceive others. Good, then, you are spotted

from the first, and they do what I had counted on their doing--a

mathematical certainty to any one who uses his gray cells properly--use

you as a decoy. They set the girl on--By the way, _mon ami_, as an

interesting fact psychologically, has she got red hair?"

"If you mean Miss Martin," I said coldly. "Her hair is a delicate shade

of auburn, but--"

"They are _épatant_--these people! They have even studied your

psychology. Oh! yes, my friend, Miss Martin was in the plot--very

much so. She repeats the letter to you, together with her tale of Mr.

Ryland's wrath, you write it down, you puzzle your brains--the cipher

is nicely arranged, difficult, but not too difficult--you solve it, and

you send for me."

"But what they do not know is that I am waiting for just this very

thing to happen. I go post haste to Japp and arrange things. And so, as

you see, all is triumph!"

I was not particularly pleased with Poirot, and I told him so. We went

back to London on a milk train in the early hours of the morning, and a

most uncomfortable journey it was.

I was just out of my bath and indulging in pleasurable thoughts of

breakfast when I heard Japp's voice in the sitting-room. I threw on a

bathrobe and hurried in.

"A pretty mare's nest you've got us into this time," Japp was saying.

"It's too bad of you, M. Poirot. First time I've ever known you take a

toss."

Poirot's face was a study. Japp went on.

"There were we, taking all this Black Hand stuff seriously--and all the

time it was the footman."

"The footman?" I gasped.

"Yes, James, or whatever his name is. Seems he laid 'em a wager in

the servants' hall that he could get taken for the old man by his

nibs--that's you, Captain Hastings--and would hand him out a lot of spy

stuff about a Big Four gang."

"Impossible!" I cried.

"Don't you believe it. I marched our gentleman straight to Hatton

Chase, and there was the real Ryland in bed and asleep, and the butler

and the cook and God knows how many of them to swear to the wager. Just

a silly hoax--that's all it was--and the valet is with him."

"So that was why he kept in the shadow," murmured Poirot.

After Japp had gone we looked at each other.

"We _know_, Hastings," said Poirot at last. "Number Two of the Big

Four is Abe Ryland. The masquerading on the part of the footman was to

ensure a way of retreat in case of emergencies. And the footman--"

"Yes," I breathed.

"_Number Four_," said Poirot gravely.
