I stared at him in dumb agony.

"I think, Captain Hastings, that you will write that letter. See, I

have a cable form here. The message I shall write on it depends on you,

and means life or death for your wife."

The sweat broke out on my brow. My tormentor continued, smiling

amiably, and speaking with perfect sangfroid:--

"There, captain, the pen is ready to your hand. You have only to write.

If not--"

"If not?" I echoed.

"If not, that lady that you love dies--and dies slowly. My master,

Li Chang Yen, amuses himself in his spare hours by devising new and

ingenious methods of tortures--"

"My God!" I cried. "You fiend! Not that--you wouldn't do that--"

"Shall I recount to you some of his devices?"

Without heeding my cry of protest, his speech flowed on--evenly,

serenely--till with a cry of horror I clapped my hands to my ears.

"It is enough, I see. Take up the pen and write."

"You would not dare--"

"Your speech is foolishness, and you know it. Take up the pen and

write."

"If I do?"

"Your wife goes free. The cable shall be despatched immediately."

"How do I know that you will keep faith with me?"

"I swear it to you on the sacred tombs of my ancestors. Moreover, judge

for yourself--why should I wish to do her harm? Her detention will have

answered its purpose."

"And--and Poirot?"

"We will keep him in safe custody until we have concluded our

operations. Then we will let him go."

"Will you swear that also on the tombs of your ancestors?"

"I have sworn one oath to you. That should be sufficient."

My heart sank. I was betraying my friend--to what? For a moment I

hesitated--then the terrible alternative rose like a nightmare before

my eyes. Cinderella--in the hands of these Chinese devils, dying by

slow torture--

A groan rose to my lips. I seized the pen. Perhaps by careful wording

of the letter, I could convey a warning, and Poirot would be enabled to

avoid the trap. It was the only hope.

But even that hope was not to remain. The Chinaman's voice rose, suave

and courteous.

"Permit me to dictate to you."

He paused, consulted a sheaf of notes that lay by his side, and then

dictated as follows:--

"Dear Poirot, I think I'm on the track of Number Four. A Chinaman

came this afternoon and lured me down here with a bogus message.

Luckily I saw through his little game in time, and gave him the

slip. Then I turned the tables on him, and managed to do a bit of

shadowing on my own account--rather neatly too, I flatter myself.

I'm getting a bright young lad to carry this to you. Give him a

half a crown, will you? That's what I promised him if it was

delivered safely. I'm watching the house, and daren't leave. I

shall wait for you until six o'clock, and if you haven't come then,

I'll have a try at getting into the house on my own. It's too good

a chance to miss, and, of course, the boy mightn't find you. But

if he does, get him to bring you down here right away. And cover

up those precious moustaches of yours in case any one's watching

out from the house and might recognise you.

"Yours in haste,

"A. H."

Every word that I wrote plunged me deeper in despair. The thing was

diabolically clever. I realised how closely every detail of our life

must be known. It was just such an epistle as I might have penned

myself. The acknowledgment that the Chinaman who had called that

afternoon had endeavoured to "lure me away" discounted any good I might

have done by leaving my "sign" of four books. It _had_ been a

trap, and I had seen through it, that was what Poirot would think. The

time, too, was cleverly planned. Poirot, on receiving the note, would

have just time to rush off with his innocent-looking guide, and that

he would do so, I knew. My determination to make my way into the house

would bring him post haste. He always displayed a ridiculous distrust

of my capacities. He would be convinced that I was running into danger

without being equal to the situation, and would rush down to take

command of the situation.

But there was nothing to be done. I wrote as bidden. My captor took the

note from me, read it, then nodded his head approvingly and handed it

to one of the silent attendants who disappeared with it behind one of

the silken hangings on the wall which masked a doorway.

With a smile the man opposite to me picked up a cable form and wrote.

He handed it to me.
