Part 21 (1/2)

”To begin with it is necessary to picture exactly what pa.s.sed in Miss ArundelFs mind. That, I think, is fairly easy. She has a fall, her fall is supposed to be occasioned by a dog's ball, but she herself knows better. Lying there on her bed her active and shrewd mind goes over the circ.u.mstances of her fall and she comes to a very definite conclusion about it. Some one has deliberately tried to injure--perhaps to kill her.

”From that conclusion she pa.s.ses to a consideration of who that person can be. There were seven people in the house--four guests, her companion and two servants. Of these seven people only one can be entirely exonerated--since to that one person no advantage could accrue. She does not seriously suspect the two servants, both of whom have been with her for many years and whom she knows to be devoted to her. There remain then, four persons, three of them members of her family, and one of them a connection by marriage. Each of those four persons benefit, three directly, one indirectly, by her death.

”She is in a difficult position, since she is a woman with a strong sense of family feeling.

Essentially she is not one who wishes to wash the dirty linen in public, as the saying goes. On the other hand, she is not one to submit tamely to attempted murder!

”She takes her decision and writes to me.She also takes a further step. That further step was, I believe, actuated by two motives.

One, I think, was a distant feeling of spite against her entire family! She suspected them all impartially, and she determined at all costs to score off them! The second and more reasoned motive was a wish to protect herself and a realization of how this could be accomplished. As you know, she wrote to her lawyer, Mr. Pur vis, and directed him to draw up a will in favour of the one person in the house whom, she felt convinced, could have had no hand in her accident.

”Now I may say that, from the terms of her letter to me and from her subsequent actions, I am quite sure that Miss Arundell pa.s.sed from indefinite suspicion of four people to definite suspicion of one of those four.

The whole tenor of her letter to me is an insistence that this business must be kept strictly private, since the honour of the family is involved.

”I think that, from a Victorian point of view, this means that a person of her own name was indicated--and preferably a man.

”If she had suspected Mrs. Tanios she would have been quite as anxious to secure her own safety, but not quite as concerned for the family honour. She might have felt much the same about Theresa Arundell, but not nearly as intensely as she would feel about Charles.

”Charles was an Arundell. He bore the family name! Her reasons for suspecting him seem quite clear. To begin with, she had no illusions about Charles. He had come near to disgracing the family once before. That is, she knew him to be not only a potential but an actual criminal! He had already forged her name to a cheque. After forgery--a step further--murder!

”Also she had had a somewhat suggestive conversation with him only two days before her accident. He had asked her for money and she had refused and he had thereupon remarked--oh, lightly enough--that she was going the right way to get herself b.u.mped off. To this she had responded that she could take care of herself! To this, we are told, her nephew responded, 'Don't be too sure.' And two days later this sinister accident takes place.

”It is hardly to be wondered at that lying there and brooding over the occurrence, Miss Arundell came definitely to the conclusion that it was Charles Arundell who had made an attempt upon her life.

”The sequence of events is perfectly clear.

The conversation with Charles. The accident.

The letter written to me in great distress of mind. The letter to the lawyer. On the following Tuesday, the 21st, Mr. Purvis brings the will and she signs it.

”Charles and Theresa Arundell come down the following week-end and Miss Arundell at once takes the necessary steps to safeguard herself. She tells Charles about the will. She not only tells him but she actually shows it to him! That, to my mind, is absolutely conclusive. She is making it quite clear to a would-be murderer that murder would bring him nothing whatever!

”She probably thought that Charles would pa.s.s on that information to his sister. But he did not do so. Why? I fancy that he had a very good reason--he felt guilty! He believed that it was his doingthat the will had been made. But why did he feel guilty? Because he had really attempted murder?

Or merely because he had helped himself to a small sum of ready cash? Either the serious crime or the petty one might account for his reluctance. He said nothing, hoping that his aunt would relent and change her mind.

”As far as Miss ArundelFs state of mind was concerned I felt that I had reconstructed events with a fair amount of correctness. I had next to make up my mind if her suspicions were, in actual fact, justified.

”Just as she had done, I realized that my suspicions were limited to a narrow circle-- seven people to be exact. Charles and Theresa Arundell, Dr. Tanios and Mrs. Tanios, the two servants, and Miss Lawson. There was an eighth person who had to be taken into account--namely. Dr.

Donaldson, who dined there that night, but I did not learn of his presence until later.

”These seven persons that I was considering fell easily into two categories. Six of them stood to benefit in a greater or lesser degree by Miss ArundelFs death. If any one of those six had committed the crime the reason was probably a plain matter of gain. The second category contained one person only--Miss Lawson. Miss Lawson did not stand to gain by Miss Arundell's death, but as a result of the accident, she did benefit considerably later!

”That meant that if Miss Lawson staged the so-called accident--” ”I never did anything of the kind!” Miss Lawson interrupted. ”It's disgraceful!

Standing up there and saying such things!” ”A little patience, mademoiselle. And be kind enough not to interrupt,” said Poirot.

Miss Lawson tossed her head angrily.

”I insist on making my protest! Disgraceful, that's what it is! Disgraceful!” Poirot went on, unheeding.

”I was saying that i/Miss Lawson staged that accident she did so for an entirely different reason--that is, she engineered it so that Miss Arundell would naturally suspect her own family and become alienated from them.

That was a possibility! I searched to see if there were any confirmation or otherwise and I unearthed one very definite fact. If Miss Lawson wanted Miss Arundell to suspect her own family, she would have stressed the fact of the dog. Bob, being out that night.

But on the contrary Miss Lawson took the utmost pains to prevent Miss Arundell hearing of that.

Therefore, I argued. Miss Lawson must be innocent.” Miss Lawson said sharply: ”I should hope so!” ”I next considered the problem of Miss Arundell5 s death. If one attempt to murder a person is made, a second attempt usually follows. It seemed to me significant that within a fortnight of the first attempt Miss Arundell should have died. I began to make inquiries.

”Dr. Grainger did not seem to think there was anything unusual about his patient's death. That was a little damping to my theory.

But, inquiring into the happenings of the last evening before she was taken ill, I came across a rather significant fact. Miss Isabel Tripp mentioned a halo of light that had appeared round Miss Arundell5 s head.Her sister confirmed her statement. They might, of course, be inventing--in a romantic spirit--but I did not think that the incident was quite a likely one to occur to them unprompted. When questioning Miss Lawson she also gave me an interesting piece of information. She referred to a luminous ribbon issuing from Miss ArundelFs mouth and forming a luminous haze round her head.

”Obviously, though described somewhat differently by two different observers 5 the actual fact was the same. What it amounted to, shorn of spiritualistic significance, was this: On the night in question Miss ArundelFs breath was phosph.o.r.escent!” Dr. Donaldson moved a little in his chair.

Poirot nodded to him.

”Yes, you begin to see. There are not very many phosph.o.r.escent substances. The first and most common one gave me exactly what I was looking for. I will read you a short extract from an article on phosphorus poisoning.

”The person's breath may be phosph.o.r.escent before he feels in any way affected. That is what Miss Lawson and the Misses Tripp saw in the dark--Miss ArundelFs phosph.o.r.escent breath--'a luminous haze.' And here I will read you again. The jaundice having thoroughly p.r.o.nounced itself, the system may be considered as not only under the influence of the toxic action of phosphorus, but as suffering in addition from all the accidents incidental to the retention of the biliary secretion in the blood, nor is therefrom this point any special difference between phosphorus poisoning and certain affections of the liver--such for example as yellow atrophy.

”You see the cleverness of that? Miss Arundell has suffered for years from liver trouble. The symptoms of phosphorus poisoning would only look like another attack of the same complaint.

There will be nothing new, nothing startling about it.

”Oh! it was well planned! Foreign matches--vermin paste? It is not difficult to get hold of phosphorus, and a very small dose will kill. The medicinal dose is from 1/100 to 1/30 grain.

”Voila. How clear--how marvellously clear the whole business becomes! Naturally, the doctor is deceived--especially as I find his sense of smell is affected--the garlic odour of the breath is a distinct symptom of phosphorus poisoning. He had no suspicions--why should he have? There were no suspicious circ.u.mstances and the one thing that might have given him a hint was the one thing he would never hear--or if he did hear it he would only cla.s.s it as spiritualistic nonsense.

”I was now sure (from the evidence of Miss Lawson and the Misses Tripp) that murder had been committed. The question still was by whom? I eliminated the servants--their mentality was obviously not adapted to such a crime. I eliminated Miss Lawson, since she would hardly have prattled on about luminous ectoplasm if she had been connected with the crime. I eliminated Charles Arundell, since he knew, having seen the will, that he would gain nothing by his aunts death.

”There remained his sister Theresa, Dr.

Tanios, Mrs. Tanios and Dr. Donaldson, who I discovered to have been dining in the house on the evening of the dog's ball incident.

”At this point I had very little to help me.I had to fall back upon the psychology of the crime and the personality of the murderer!

Both crimes had roughly the same outline. They were both simple. They were cunning, and carried out with efficiency. They required a certain amount of knowledge but not a great deal. The facts about phosphorus poisoning are easily learned, and the stuff itself, as I say, is quite easily obtained, especially abroad.

”I considered first the two men. Both of them were doctors, and both were clever men. Either of them might have thought of phosphorus and its suitability in this particular case, but the incident of the dog's ball did not seem to fit a masculine mind. The incident of the ball seemed to me essentially a woman's idea.

”I considered first of all Theresa Arundell.

She had certain potentialities. She was bold, ruthless, and not overscrupulous. She had led a selfish and greedy life. She had always had everything she wanted and she had reached a point where she was desperate for money--both for herself and for the man she loved. Her manner, also, showed plainly that she knew her aunt had been murdered.

”There was an interesting little pa.s.sage between her and her brother. I conceived the idea that each suspected the other of the crime. Charles endeavoured to make her say that she knew of the existence of the new will. Why? Clearly because if she knew of it she could not be suspected of the murder. She, on the other hand, clearly did not believe Charles's statement that Miss Arundell had shown it to him! She regarded it as a singularly clumsy attempt on his part to divert suspicion from himself.

”There was another significant point.
