"Why did two Italians fight a duel? Why did a young man shoot himself? Jock McLaren is an inarticulate man. He has resigned himself, perhaps, to being the faithful friend to you and your husband, but then comes Major Rich as well. It is too much! In the darkness of hate and desire, he plans what is well nigh the perfect murder - a double murder, for he is almost certain to be found guilty of it. And with Rich and your husband both out of the way - he thinks that at last you may turn to him. And perhaps, madame, you would have done... Eh?"
She was staring at him, wide-eyed, horror-struck. Almost unconsciously she breathed:
"Perhaps... I don't know..."
Inspector Miller spoke with sudden authority.
"This is all very well, Poirot. It's a theory, nothing more. There's not a shred of evidence, probably not a word of it is true."
"It is all true."
"But there's no evidence. There's nothing we can act on."
"You are wrong. I think that McLaren, if this is put to him, will admit it. That is, if it is made clear to him that Margharita Clayton knows... "
Poirot paused and added:
"Because, once he knows that, he has lost. The perfect murder has been in vain."
THE HARLEQUIN TEA SET
Mr. Satterthwaite clucked twice in vexation. Whether right in his assumption or not, he was more and more convinced that cars nowadays broke down far more frequently than they used to do. The only cars he trusted were old friends who had survived the test of time. They had their little idiosyncrasies, but you knew about those, provided for them, fulfilled their wants before the demand became too acute. But new cars! Full of new gadgets, different kinds of windows, an instrument panel newly and differently arranged, handsome in its glistening wood, but being unfamiliar, your groping hand hovered uneasily over fog lights, windshield wipers, the choke, etcetera. All these things with knobs in a place where you didn't expect them. And when your gleaming new purchase failed in performance, your local garage uttered the intensely irritating words: "Teething troubles. Splendid car, sir, these roadsters Super Superbos. All the latest accessories. But bound to have their teething troubles, you know. Ha, ha." Just as though a car was a baby.
But Mr. Satterthwaite, being now of an advanced age, was strongly of the opinion that a new car ought to be fully adult. Tested, inspected, and its teething troubles already dealt with before it came into its purchaser's possession.
Mr. Satterthwaite was on his way to pay a weekend visit to friends in the country. His new car had already, on the way from London, given certain symptoms of discomfort, and was now drawn up in a garage waiting for the diagnosis, and how long it would take before he could resume progress towards his destination. His chauffeur was in consultation with a mechanic. Mr. Satterthwaite sat, striving for patience. He had assured his hosts, on the telephone the night before, that he would be arriving in good time for tea. He would reach Doverton Kingsbourne, he assured them, well before four o'clock.
He clucked again in irritation and tried to turn his thoughts to something pleasant. It was no good sitting here in a state of acute irritation, frequently consulting his wristwatch, clucking once more and giving, he had to realize, a very good imitation of a hen pleased with its prowess in laying an egg.
Yes. Something pleasant. Yes, now hadn't there been something - something he had noticed as they were driving along. Not very long ago. Something that he had seen through the window which had pleased and excited him. But before he had had time to think about it, the car's misbehavior had become more pronounced and a rapid visit to the nearest service station had been inevitable.
What was it that he had seen? On the left - no, on the right. Yes, on the right as they drove slowly through the village street. Next door to a post office. Yes, he was quite sure of that. Next door to a post office because the sight of the post office had given him the idea of telephoning to the Addisons to break the news that he might be slightly late in his arrival. The post office. A village post office. And next to it - yes, definitely, next to it, next door or if not next door the door after. Something that had stirred old memories, and he had wanted - just what was it that he had wanted? Oh dear, it would come to him presently. It was mixed up with a color. Several colors. Yes, a color or colors. Or a word. Some definite word that had stirred memories, thoughts, pleasures gone by, excitement, recalling something that had been vivid and alive. Something in which he himself had not only seen but observed. No, he had done more. He had taken part. Taken part in what, and why, and where? All sorts of places. The answer came quickly at the last thought. All sorts of places.
