"I will ask you nothing. It is enough for me that it is as I thought. And I.I, too, have an instinct. We are

working together towards a common end."

"Don't ask me to help you, because I won't. I wouldn't lift a finger to.to.." She faltered.

"You will help me in spite of yourself. I ask you nothing.but you will be my ally. You will not be able to

help yourself. You will do the only thing that I want of you."

"And that is?"

"You will watch!"

Evelyn Howard bowed her head.

"Yes, I can't help doing that. I am always watching.always hoping I shall be proved wrong."

"If we are wrong, well and good," said Poirot. "No one will be more pleased than I shall. But, if we are right?

If we are right, Miss Howard, on whose side are you then?""I don't know, I don't know..""Come now.""It could be hushed up.""There must be no hushing up.""But Emily herself.." She broke off."Miss Howard," said Poirot gravely, "this is unworthy of you."Suddenly she took her face from her hands."Yes," she said quietly, "that was not Evelyn Howard who spoke!" She flung her head up proudly. "This is Evelyn Howard! And she is on the side of Justice! Let the cost be what it may." And with these words, she

walked firmly out of the room.

"There," said Poirot, looking after her, "goes a very valuable ally. That woman, Hastings, has got brains as well as a heart."

I did not reply.

"Instinct is a marvellous thing," mused Poirot. "It can neither be explained nor ignored."

"You and Miss Howard seem to know what you are talking about," I observed coldly. "Perhaps you don't

realize that I am still in the dark."

"Really? Is that so, mon ami?"

"Yes. Enlighten me, will you?"

Poirot studied me attentively for a moment or two. Then, to my intense surprise, he shook his head decidedly.

"No, my friend."

"Oh, look here, why not?"

"Two is enough for a secret."

"Well, I think it is very unfair to keep back facts from me."

"I am not keeping back facts. Every fact that I know is in your possession. You can draw your own

deductions from them. This time it is a question of ideas."

"Still, it would be interesting to know."Poirot looked at me very earnestly, and again shook his head."You see," he said sadly, "you have no instincts.""It was intelligence you were requiring just now," I pointed out."The two often go together," said Poirot enigmatically.The remark seemed so utterly irrelevant that I did not even take the trouble to answer it. But I decided that if I made any interesting and important discoveries.as no doubt I should.I would keep them to myself, and surprise Poirot with the ultimate result.

There are times when it is one's duty to a.s.sert oneself.

CHAPTER IX.

DR. BAUERSTEIN

I HAD had no opportunity as yet of pa.s.sing on Poirot's message to Lawrence. But now, as I strolled out on the lawn, still nursing a grudge against my friend's high-handedness, I saw Lawrence on the croquet lawn, aimlessly knocking a couple of very ancient b.a.l.l.s about, with a still more ancient mallet.

It struck me that it would be a good opportunity to deliver my message. Otherwise, Poirot himself might relieve me of it. It was true that I did not quite gather its purport, but I flattered myself that by Lawrence's reply, and perhaps a little skillful cross-examination on my part, I should soon perceive its significance. Accordingly I accosted him.

"I've been looking for you," I remarked untruthfully.

"Have you?"

"Yes. The truth is, I've got a message for you.from Poirot."

"Yes?"

"He told me to wait until I was alone with you," I said, dropping my voice significantly, and watching him

intently out of the corner of my eye. I have always been rather good at what is called, I believe, creating an atmosphere.

"Well?"

There was no change of expression in the dark melancholic face. Had he any idea of what I was about to say?

"This is the message." I dropped my voice still lower. " 'Find the extra coffee-cup, and you can rest in peace.'

"What on earth does he mean?" Lawrence stared at me in quite unaffected astonishment.

"Don't you know?"

"Not in the least. Do you?"

I was compelled to shake my head.

"What extra coffee-cup?"

"I don't know."

"He'd better ask Dorcas, or one of the maids, if he wants to know about coffee-cups. It's their business, not

mine. I don't know anything about the coffee-cups, except that we've got some that are never used, which are

a perfect dream! Old Worcester. You're not a connoisseur, are you, Hastings?"

I shook my head.

"You miss a lot. A really perfect bit of old china.it's pure delight to handle it, or even to look at it."

"Well, what am I to tell Poirot?"

"Tell him I don't know what he's talking about. It's double Dutch to me."

"All right."

I was moving off towards the house again when he suddenly called me back.

"I say, what was the end of that message? Say it over again, will you?"

" 'Find the extra coffee-cup, and you can rest in peace.' Are you sure you don't know what it means?" I asked him earnestly.

He shook his head.

"No," he said musingly, "I don't. I.I wish I did."

The boom of the gong sounded from the house, and we went in together. Poirot had been asked by John to

remain to lunch, and was already seated at the table.

By tacit consent, all mention of the tragedy was barred. We conversed on the war, and other outside topics.
