"I must hurry on," I said, thankful that he did not ask me whither I was bound.

In a few minutes I was knocking at the door of Leastways Cottage.

Getting no answer, I repeated my summons impatiently. A window above me was cautiously opened, and Poirot himself looked out.

He gave an exclamation of surprise at seeing me. In a few brief words, I explained the tragedy that had occurred, and that I wanted his help.

"Wait, my friend, I will let you in, and you shall recount to me the affair whilst I dress."

In a few moments he had unbarred the door, and I followed him up to his room. There he installed me in a chair, and I related the whole story, keeping back nothing, and omitting no circ.u.mstance, however insignificant, whilst he himself made a careful and deliberate toilet.

I told him of my awakening, of Mrs. Inglethorp's dying words, of her husband's absence, of the quarrel the day before, of the sc.r.a.p of conversation between Mary and her mother-in-law that I had overheard, of the former quarrel between Mrs. Inglethorp and Evelyn Howard, and of the latter's innuendoes.

I was hardly as clear as I could wish. I repeated myself several times, and occasionally had to go back to some detail that I had forgotten. Poirot smiled kindly on me.

"The mind is confused? Is it not so? Take time, mon ami. You are agitated; you are excited.it is but natural. Presently, when we are calmer, we will arrange the facts, neatly, each in his proper place. We will examine.and reject. Those of importance we will put on one side; those of no importance, pouf!".he screwed up his cherub-like face, and puffed comically enough."blow them away!"

"That's all very well," I objected, "but how are you going to decide what is important, and what isn't? That always seems the difficulty to me."

Poirot shook his head energetically. He was now arranging his moustache with exquisite care.

"Not so. Voyons! One fact leads to another.so we continue. Does the next fit in with that? A merveille! Good! We can proceed. This next little fact.no! Ah, that is curious! There is something missing.a link in the chain that is not there. We examine. We search. And that little curious fact, that possibly paltry little detail that will not tally, we put it here!" He made an extravagant gesture with his hand. "It is significant! It is tremendous!"

"Y.es."

"Ah!" Poirot shook his forefinger so fiercely at me that I quailed before it. "Beware! Peril to the detective who says: 'It is so small.it does not matter. It will not agree. I will forget it.' That way lies confusion! Everything matters."

"I know. You always told me that. That's why I have gone into all the details of this thing whether they

seemed to me relevant or not."

"And I am pleased with you. You have a good memory, and you have given me the facts faithfully. Of the order in which you present them, I say nothing.truly, it is deplorable! But I make allowances.you are upset.

To that I attribute the circ.u.mstance that you have omitted one fact of paramount importance."

"What is that?" I asked.

"You have not told me if Mrs. Inglethorp ate well last night."

I stared at him. Surely the war had affected the little man's brain. He was carefully engaged in brushing his

coat before putting it on, and seemed wholly engrossed in the task.

"I don't remember," I said. "And, anyway, I don't see.."

"You do not see? But it is of the first importance."

"I can't see why," I said, rather nettled. "As far as I can remember, she didn't eat much. She was obviously

upset, and it had taken her appet.i.te away. That was only natural."

"Yes," said Poirot thoughtfully, "it was only natural."

He opened a drawer, and took out a small despatch-case, then turned to me.

"Now I am ready. We will proceed to the chateau, and study matters on the spot. Excuse me, mon ami, you

dressed in haste, and your tie is on one side. Permit me." With a deft gesture, he rearranged it.

"Ca y est! Now, shall we start?"

We hurried up the village, and turned in at the lodge gates. Poirot stopped for a moment, and gazed

sorrowfully over the beautiful expanse of park, still glittering with morning dew.

"So beautiful, so beautiful, and yet, the poor family, plunged in sorrow, prostrated with grief."

He looked at me keenly as he spoke, and I was aware that I reddened under his prolonged gaze.

Was the family prostrated by grief? Was the sorrow at Mrs. Inglethorp's death so great? I realized that there

was an emotional lack in the atmosphere. The dead woman had not the gift of commanding love. Her death

was a shock and a distress, but she would not be pa.s.sionately regretted.

Poirot seemed to follow my thoughts. He nodded his head gravely.

"No, you are right," he said, "it is not as though there was a blood tie. She has been kind and generous to these Cavendishes, but she was not their own mother. Blood tells.always remember that.blood tells."

"Poirot," I said, "I wish you would tell me why you wanted to know if Mrs. Inglethorp ate well last night? I have been turning it over in my mind, but I can't see how it has anything to do with the matter?"

He was silent for a minute or two as we walked along, but finally he said:

"I do not mind telling you.though, as you know, it is not my habit to explain until the end is reached. The present contention is that Mrs. Inglethorp died of strychnine poisoning, presumably administered in her coffee."

"Yes?"

"Well, what time was the coffee served?"

"About eight o'clock."

"Therefore she drank it between then and half-past eight. certainly not much later. Well, strychnine is a

fairly rapid poison. Its effects would be felt very soon, probably in about an hour. Yet, in Mrs. Inglethorp's case, the symptoms do not manifest themselves until five o'clock the next morning: nine hours! But a heavy meal, taken at about the same time as the poison, might r.e.t.a.r.d its effects, though hardly to that extent. Still, it is a possibility to be taken into account. But, according to you, she ate very little for supper, and yet the symptoms do not develop until early the next morning! Now that is a curious circ.u.mstance, my friend. Something may arise at the autopsy to explain it. In the meantime, remember it."

As we neared the house, John came out and met us. His face looked weary and haggard.

"This is a very dreadful business, Monsieur Poirot," he said. "Hastings has explained to you that we are anxious for no publicity?"

"I comprehend perfectly."

"You see, it is only suspicion so far. We have nothing to go upon."

"Precisely. It is a matter of precaution only."

John turned to me, taking out his cigarette-case, and lighting a cigarette as he did so.

"You know that fellow Inglethorp is back?"

"Yes. I met him."

John flung the match into an adjacent flower bed, a proceeding which was too much for Poirot's feelings. He

retrieved it, and buried it neatly.

"It's jolly difficult to know how to treat him."

"That difficulty will not exist long," p.r.o.nounced Poirot quietly.

John looked puzzled, not quite understanding the portent of this cryptic saying. He handed the two keys

which Dr. Bauerstein had given him to me.

"Show Monsieur Poirot everything he wants to see."

"The rooms are locked?" asked Poirot.

"Dr. Bauerstein considered it advisable."

Poirot nodded thoughtfully.

"Then he is very sure. Well, that simplifies matters for us."

We went up together to the room of the tragedy. For convenience I append a plan of the room and the

princ.i.p.al articles of furniture in it.

Poirot locked the door on the inside, and proceeded to a minute inspection of the room. He darted from one

object to the other with the agility of a gra.s.shopper. I remained by the door, fearing to obliterate any clues.

Poirot, however, did not seem grateful to me for my forbearance.

"What have you, my friend," he cried, "that you remain there like.how do you say it?.ah, yes, the stuck

pig?"

I explained that I was afraid of obliterating any foot-marks.

"Foot-marks? But what an idea! There has already been practically an army in the room! What foot-marks

are we likely to find? No, come here and aid me in my search. I will put down my little case until I need it."

He did so, on the round table by the window, but it was an ill-advised proceeding; for, the top of it being loose, it tilted up, and precipitated the despatch-case on the floor.

"Eh voila une table!" cried Poirot. "Ah, my friend, one may live in a big house and yet have no comfort."
