“Yes?”
“Do you ever prescribe chloral for your wife?”
Tanios gave a startled movement.
“I—no—at least I may have done. But not lately. She seems to have taken an aversion to any form of sleeping draught.”
“Ah! I suppose because she does not trust you?”
“M. Poirot!”
Tanios came striding forward angrily.
“That would be part of the disease,” said Poirot smoothly.
“Yes, yes, of course.”
“She is probably highly suspicious of anything you give her to eat or drink. Probably suspects you of wanting to poison her?”
“Dear me, M. Poirot, you are quite right. You know something of such cases, then?”
“One comes across them now and then in my profession, naturally. But do not let me detain you. You may find her waiting for you at the hotel.”
“True. I hope I shall. I feel terribly anxious.”
He hurried out of the room.
Poirot went swiftly to the telephone. He flicked over the pages of the telephone directory and asked for a number.
“Allo—Allo—is that the Durham Hotel. Can you tell me if Mrs. Tanios is in? What? T A N I O S. Yes, that is right. Yes? Yes? Oh, I see.”
He replaced the receiver.
“Mrs. Tanios left the hotel this morning early. She returned at eleven, waited in the taxi whilst her luggage was brought down and drove away with it.”
“Does Tanios know she took away her luggage?”
“I think not as yet.”
“Where has she gone?”
“Impossible to tell.”
“Do you think she will come back here?”
“Possibly. I cannot tell.”
“Perhaps she will write.”
“Perhaps.”
“What can we do?”
Poirot shook his head. He looked worried and distressed.
“Nothing at the moment. A hasty lunch and then we will go and see Theresa Arundell.”
“Do you believe it was her on the stairs?”
“Impossible to tell. One thing I made sure of—Miss Lawson could not have seen her face. She saw a tall figure in a dark dressing gown, that is all.”
“And the brooch.”
“My dear friend, a brooch is not part of a person’s anatomy! It can be detached from that person. It can be lost—or borrowed—or even stolen.”
“In other words you don’t want to believe Theresa Arundell guilty.”
“I want to hear what she has to say on the matter.”
“And if Mrs. Tanios comes back?”
“I will arrange for that.”
George brought in an omelette.
“Listen, George,” said Poirot. “If that lady comes back, you will ask her to wait. If Dr. Tanios comes while she is here on no account let him in. If he asks if his wife is here, you will tell him she is not. You understand?”
“Perfectly, sir.”
Poirot attacked the omelette.
“This business complicates itself,” he said. “We must step very carefully. If not—the murderer will strike again.”
“If he did you might get him.”
“Quite possibly, but I prefer the life of the innocent to the conviction of the guilty. We must go very, very carefully.”

THERESA’S DENIAL
We found Theresa Arundell just preparing to go out.
She was looking extraordinarily attractive. A small hat of the most outrageous fashion descended rakishly over one eye. I recognized with momentary amusement that Bella Tanios had worn a cheap imitation of such a hat yesterday and had worn it—as George had put it—on the back of the head instead of over the right eye. I remembered well how she had pushed it farther and farther back on her untidy hair.
Poirot said, politely:
“Can I have just a minute or two, mademoiselle, or will it delay you too much?”
Theresa laughed.
“Oh, it doesn’t matter. I’m always three-quarters of an hour late for everything. I might just as well make it an hour.”
She led him into the sitting room. To my surprise Dr. Donaldson rose from a chair by the window.
“You’ve met M. Poirot already, Rex, haven’t you?”
“We met at Market Basing,” said Donaldson, stiffly.
“You were pretending to write the life of my drunken grandfather, I understand,” said Theresa. “Rex, my angel, will you leave us?”
“Thank you, Theresa, but I think that from every point of view it would be advisable for me to be present at this interview.”
There was a brief duel of eyes. Theresa’s were commanding. Donaldson’s were impervious. She showed a quick flash of anger.
“All right, stay then, damn you!”
Dr. Donaldson seemed unperturbed.
He seated himself again in the chair by the window, laying down his book on the arm of it. It was a book on the pituitary gland, I noticed.
Theresa sat down on her favourite low stool and looked impatiently at Poirot.
“Well, you’ve seen Purvis? What about it?”
Poirot said in a noncommittal voice:
“There are—possibilities, mademoiselle.”
She looked at him thoughtfully. Then she sent a very faint glance in the direction of the doctor. It was, I think, intended as a warning to Poirot.
“But it would be well, I think,” went on Poirot, “for me to report later when my plans are more advanced.”
A faint smile showed for a minute on Theresa’s face.
Poirot continued:
“I have today come from Market Basing and while there I have talked to Miss Lawson. Tell me, mademoiselle, did you on the night of April 13th (that was the night of the Easter Bank Holiday) kneel upon the stairs after everyone had gone to bed?”
“My dear Hercule Poirot, what an extraordinary question. Why should I?”
“The question, mademoiselle, is not why you should, but whether you did.”
“I’m sure I don’t know. I should think it most unlikely.”
“You comprehend, mademoiselle, Miss Lawson says you did.”
Theresa shrugged her attractive shoulders.
“Does it matter?”
“It matters very much.”
She stared at him. In a perfectly amiable fashion, Poirot stared back.
“Loopy!” said Theresa.
“Pardon?”
“Definitely loopy!” said Theresa. “Don’t you think so, Rex?”
Dr. Donaldson coughed.
“Excuse me, M. Poirot, but what is the point of the question?”
My friend spread out his hands.
“It is most simple! Someone drove in a nail in a convenient position at the head of the stairs. The nail was just touched with brown varnish to match the skirting board.”
“Is this a new kind of witchcraft?” asked Theresa.
“No, mademoiselle, it is much more homely and simple than that. On the following evening, the Tuesday, someone attached a string of thread from the nail to the balusters with the result that when Miss Arundell came out of her room she caught her foot in it and went headlong down the stairs.”
Theresa drew in her breath sharply.
“That was Bob’s ball!”
“Pardon, it was not.”
There was a pause. It was broken by Donaldson who said in his quiet, precise voice:
“Excuse me, but what evidence have you in support of this statement?”
Poirot said quietly:
“The evidence of the nail, the evidence of Miss Arundell’s own written words, and finally the evidence of Miss Lawson’s eyes.”
Theresa found her voice.
“She says I did it, does she?”
Poirot did not answer except by bending his head a little.
“Well, it’s a lie! I had nothing to do with it!”
“You were kneeling on the stairs for quite another reason?”
“I wasn’t kneeling on the stairs at all!”
“Be careful, mademoiselle.”
“I wasn’t there! I never came out of my room after I went to bed on any evening I was there.”
“Miss Lawson recognized you.”
“It was probably Bella Tanios or one of the maids she saw.”
“She says it was you.”
“She’s a damned liar!”
“She recognized your dressing gown and a brooch you wear.”
“A brooch—what brooch?”
“A brooch with your initials.”
“Oh, I know the one! What a circumstantial liar she is!”
“You still deny that it was you she saw?”
“If it’s my word against hers—”
“You are a better liar than she is—eh?”
Theresa said, calmly:
“That’s probably quite true. But in this case I’m speaking the truth. I wasn’t preparing a booby trap, or saying my prayers, or picking up gold or silver, or doing anything at all on the stairs.”
“Have you this brooch that was mentioned?”
“Probably. Do you want to see it?”
“If you please, mademoiselle.”
Theresa got up and left the room. There was an awkward silence. Dr. Donaldson looked at Poirot much as I imagined he might have looked at an anatomical specimen.
Theresa returned.
“Here it is.”
She almost flung the ornament at Poirot. It was a large rather showy chromium or stainless steel brooch with T.A. enclosed in a circle. I had to admit that it was large enough and showy enough to be easily seen in Miss Lawson’s mirror.
“I never wear it now. I’m tired of it,” said Theresa. “London’s been flooded with them. Every little skivvy wears one.”
“But it was expensive when you bought it?”
“Oh, yes. They were quite exclusive to begin with.”
“When was that?”
“Last Christmas, I think it was. Yes, about then.”
“Have you ever lent it to anyone?”
“No.”
“You had it with you at Littlegreen House?”
“I suppose I did. Yes, I did. I remember.”
“Did you leave it about at all? Was it out of your possession while you were there?”
“No, it wasn’t. I wore it on a green jumper. I remember. And I wore the same jumper every day.”
“And at night?”
“It was still in the jumper.”
“And the jumper.”
“Oh, hell, the jumper was sitting on a chair.”
“You are sure no one removed the brooch and put it back again the next day?”
“We’ll say so in court if you like—if you think that’s the best lie to tell! Actually I’m quite sure that nothing like that happened! It’s a pretty idea that somebody framed me—but I don’t think it’s true.”
Poirot frowned. Then he got up, attached the brooch carefully to his coat lapel and approached a mirror on a table at the other end of the room. He stood in front of it and then moved slowly backward, getting an effect of distance.
Then he uttered a grunt.
“Imbecile that I am! Of course!”
He came back and handed the brooch to Theresa with a bow.
“You are quite right, mademoiselle. The brooch did not leave your possession! I have been regrettably dense.”
“I do like modesty,” said Theresa, pinning the brooch on carelessly.
She looked up at him.
“Anything more? I ought to be going.”
“Nothing that cannot be discussed later.”
Theresa moved towards the door. Poirot went on in a quiet voice:
“There is a question of exhumation, it is true—”
Theresa stopped dead. The brooch fell to the ground.
“What’s that?”
Poirot said clearly:
“It is possible that the body of Miss Emily Arundell may be exhumed.”
Theresa stood still, her hands clenched. She said in a low, angry voice:
“Is this your doing? It can’t be done without an application from the family!”
“You are wrong, mademoiselle. It can be done on an order from the Home Office.”
“My God!” said Theresa.
She turned and walked swiftly up and down.
Donaldson said quietly:
“I really don’t see that there is any need to be upset, Tessa. I daresay that to an outsider the idea is not very pleasant, but—”
She interrupted him.
“Don’t be a fool, Rex!”
Poirot asked:
“The idea disturbs you, mademoiselle?”
“Of course it does! It isn’t decent. Poor old Aunt Emily. Why the devil should she be exhumed?”
“I presume,” said Donaldson, “that there is some doubt as to the cause of death?” He looked inquiringly at Poirot. He went on. “I confess that I am surprised. I think that there is no doubt that Miss Arundell died a natural death from a disease of long standing.”
“You told me something about a rabbit and liver trouble once,” said Theresa. “I’ve forgotten it now, but you infect a rabbit with blood from a person with yellow atrophy of the liver, and then you inject that rabbit’s blood into another rabbit, and then that second rabbit’s blood into a person and the person gets a diseased liver. Something like that.”
“That was merely an illustration of serum therapeutics,” said Donaldson patiently.
“Pity there are so many rabbits in the story!” said Theresa with a reckless laugh. “None of us keep rabbits.” She turned on Poirot and her voice altered.
“M. Poirot, is this true?” she asked.
“It is true enough, but—there are ways of avoiding such a contingency, mademoiselle.”
“Then avoid it!” her voice sank almost to a whisper. It was urgent, compelling. “Avoid it at all costs!”
Poirot rose to his feet.
“Those are your instructions?” His voice was formal.
“Those are my instructions.”
“But Tessa—” Donaldson interrupted.
She whirled round on her fiancé.
“Be quiet! She was my aunt, wasn’t she? Why should my aunt be dug up? Don’t you know there will be paragraphs in the papers and gossip and general unpleasantness?” She swung round again on Poirot.
“You must stop it! I give you carte blanche. Do anything you like, but stop it!”
Poirot bowed formally.
“I will do what I can. Au revoir, mademoiselle, au revoir, doctor.”
“Oh, go away!” cried Theresa. “And take St. Leonards with you. I wish I’d never set eyes on either of you.”
We left the room. Poirot did not this time deliberately place his ear to the crack but he dallied—yes, he dallied.
And not in vain. Theresa’s voice rose clear and defiant:
“Don’t look at me like that, Rex.”
And then suddenly, with a break in her voice—“Darling.” Dr. Donaldson’s precise voice answered her.
He said very clearly: “That man means mischief.”
Poirot grinned suddenly. He drew me through the front door. “Come, St. Leonards,” he said. “C’est drôle, ça!” Personally I thought the joke a particularly stupid one.

I LIE BACK AND REFLECT
No, I thought, as I hurried after Poirot, there was no doubt about it now. Miss Arundell had been murdered and Theresa knew it. But was she herself the criminal or was there another explanation?
She was afraid—yes. But was she afraid for herself or for someone else? Could that someone be the quiet, precise young doctor with the calm, aloof manner?
Had the old lady died of genuine disease artificially induced?
Up to a point it all fitted in—Donaldson’s ambitions, his belief that Theresa would inherit money at her aunt’s death. Even the fact that he had been at dinner there on the evening of the accident
. How easy to leave a convenient window open and return in the dead of night to tie the murderous thread across the staircase. But then, what about the placing of the nail in position?
No, Theresa must have done that. Theresa, his fiancée and accomplice. With the two of them working in together, the whole thing seemed clear enough. In that case it was probably Theresa who had actually placed the thread in position. The first crime, the crime that failed, had been her work. The second crime, the crime that had succeeded, was Donaldson’s more scientific masterpiece.
Yes—it all fitted in.
Yet even now there were loose strands. Why had Theresa blurted out those facts about inducing liver disease in human beings? It was almost as though she did not realize the truth… But in that case—and I felt my mind growing bewildered, and I interrupted my speculations to ask:
“Where are we going, Poirot?”
“Back to my flat. It is possible that we may find Mrs. Tanios there.”
My thoughts switched off on a different track.
Mrs. Tanios! That was another mystery! If Donaldson and Theresa were guilty, where did Mrs. Tanios and her smiling husband come in? What did the woman want to tell Poirot and what was Tanios’ anxiety to prevent her doing so?
“Poirot,” I said humbly. “I’m getting rather muddled. They’re not all in it, are they?”
“Murder by a syndicate? A family sydicate? No, not this time. There is the mark of one brain and one brain only in this. The psychology is very clear.”
“You mean that either Theresa or Donaldson did it—but not both of them? Did he get her to hammer that nail in on some entirely innocent pretext, then?”
“My dear friend, from the moment I heard Miss Lawson’s story I realized that there were three possibilities. (1) That Miss Lawson was telling the exact truth. (2) That Miss Lawson had invented the story for reasons of her own. (3) That Miss Lawson actually believed her own story, but that her identification rested upon the brooch—and as I have already pointed out to you—a brooch is easily detachable from its owner.”
“Yes, but Theresa insists that the brooch did not leave her possession.”
“And she is perfectly right. I had overlooked a small but intensely significant fact.”
“Very unlike you, Poirot,” I said solemnly.
“N’est ce pas? But one has one’s lapses.”
“Age will tell!”
