circumstances of that crime and was about to deliver her up to justice, she would be wild with terror; she would stop at nothing to save herself. It would be the same result, though brought about through a different reaction – not cool nerve and daring, but desperate panic.
'Then take Major Despard – a cool, resourceful man willing to try a long shot if he believed it absolutely necessary. He would weigh the pros and cons and might decide that there was a sporting chance in his favor – and he is the type of man to prefer action to inaction, and a man who would never shrink from taking the dangerous way if he believed there was a reasonable chance of success. Finally there is Mrs. Lorrimer, an elderly woman, but a woman in full possession of her wits and faculties. A cool woman. A woman with a mathematical brain. She has probably the best brain of the four. I confess that if Mrs. Lorrimer committed a crime, I should expect it to be a premeditated crime. I can see her planning a crime slowly and carefully, making sure that there were no flaws in her scheme. For that reason she seems to me slightly more unlikely than the other three. She is, however, the most dominating personality, and whatever she undertook she would probably carry through without a flaw. She is a thoroughly efficient woman.' He paused.
'So, you see, that does not help us much. No – there is only one way in this crime. We must go back into the past.'
Battle sighed. 'You've said it,' he murmured.
'In the opinion of Mr. Shaitana each of those four people had committed murder. Had he evidence? Or was it a guess? We cannot tell. It is unlikely, I think, that he could have had actual evidence in all four cases -'
'I agree with you there,' said Battle, nodding his head. 'That would be a bit too much of a coincidence.'
'I suggest that it might come about this way – murder or a certain form of murder is mentioned, and Mr. Shaitana surprised a look on someone's face. He was very quick – very sensitive to expression. It amuses him to experiment, to probe gently in the course of apparently aimless conversation; he is alert to notice a wince, a reservation, a desire to turn the conversation. Oh, it is easily done. If you suspect a certain secret, nothing is easier than to confirm your suspicion. Every time a word goes home you notice it – if you are watching for such a thing.'
'It's the sort of game that would have amused our late friend,' said Battle, nodding.
'We may assume, then, that such was the procedure in one or more cases. He may have come across a piece of actual evidence in another case and followed it up. I doubt whether, in any of the cases, he had sufficient actual knowledge with which – for instance – to have gone to the police.'
'Or it mayn't have been the kind of case,' said Battle. 'Often enough there's a fishy business – we suspect foul play, but we can't ever prove it. Anyway the course is clear. We've got to go through the records of all these people – and note any deaths that may be significant. I expect you noticed, just as the colonel did, what Shaitana said at dinner.'
'The black angel,' murmured Mrs. Oliver.
'A neat little reference to poison, to accident, to a doctor's opportunities, to shooting accidents. I shouldn't be surprised if he signed his death warrant when he said those words.'
'It was a nasty sort of pause,' said Mrs. Oliver.
'Yes,' said Poirot. 'Those words went home to one person at least – that person probably thought that Shaitana knew far more than he really did. That listener thought that they were the prelude to the end – that the party was a dramatic entertainment arranged by Shaitana leading up to arrest for murder as its climax! Yes, as you say, he signed his death warrant when he baited his guests with those words.'
There was a moment's silence.
'This will be a long business,' said Battle with a sigh. 'We can't find out all we want in a moment – and we've got to be careful. We don't want any of the four to suspect what we're doing. All our questioning and so on must seem to have to do with this murder. There mustn't be a suspicion that we've got any idea of the motive for the crime. And the devil of it is we've got to check up on four possible murders in the past, not one.'
Poirot demurred.
'Our friend Mr. Shaitana was not infallible,' he said. 'He may – it is just possible – have made a mistake.'
'About all four?'
'No – he was more intelligent than that.'
'Call it fifty-fifty?'
'Not even that. For me, I say one in four.'
'One innocent and three guilty? That's bad enough. And the devil of it is even if we get at the truth it mayn't help us. Even if somebody did push his or her great-aunt down the stairs years ago, it won't be much use to us today.'
'Yes, yes, it will be of use to us.' Poirot encouraged him. 'You know that. You know it as well as I do.'
Battle nodded slowly.
'I know what you mean,' he said. 'Same hallmark.'
'Do you mean,' said Mrs. Oliver, 'that the previous victim will have been stabbed with a dagger, too?'
'Not quite as crude as that, Mrs. Oliver,' said Battle turning to her. 'But I don't doubt it will be essentially the same type of crime. The details may be different, but the essentials underlying them will be the same. It's odd, but a criminal gives himself away every time by that.'
'Man is an unoriginal animal,' said Hercule Poirot.
'Women,' said Mrs. Oliver, 'are capable of infinite variation. I should never commit the same type of murder twice running.'
'Don't you ever write the same plot twice running?' asked Battle.
'The Lotus Murder,' murmured Poirot. 'The Clue of the Candle Wax.'
Mrs. Oliver turned on him, her eyes beaming appreciation. 'That's clever of you – that's really very clever of you. Because of course those two are exactly the same plot, but nobody else has seen it. One is stolen papers at an informal week-end party of the Cabinet, and the other's a murder in Borneo in a rubber planter's bungalow.'
'But the essential point on which the story turns is the same,' said Poirot. 'One of your neatest tricks. The rubber planter arranges his own murder; the cabinet minister arranges the robbery of his own papers. At the last minute the third person steps in and turns deception into reality.'
'I enjoyed your last, Mrs. Oliver,' said Superintendent Battle kindly. 'The one where all the chief constables were shot simultaneously. You just slipped up once or twice on official details. I know you're keen on accuracy, so I wondered if -'
Mrs. Oliver interrupted him.
'As a matter of fact I don't care two pins about accuracy. Who is accurate? Nobody nowadays. If a reporter writes that a beautiful girl of twenty-two dies by turning on the gas after looking out over the sea and kissing her favorite Labrador, Bob, good-by, does anybody make a fuss because the girl was twenty-six, the room faced inland, and the dog was a Sealyham terrier called Bonnie? If a journalist can do that sort of thing I don't see that it matters if I mix up police ranks and say a revolver when I mean an automatic and a dictograph when I mean a phonograph, and use a poison that just allows you to gasp one dying sentence and no more.
'What really matters is plenty of bodies! If the thing's getting a little dull, some more blood cheers it up. Somebody is going to tell something – and then they're killed first! That always goes down well. It comes in all my books – camouflaged different ways of course. And people like untraceable poisons, and idiotic police inspectors and girls tied up in cellars with sewer gas or water pouring in, such a troublesome way of killing anyone really, and a hero who can dispose of anything from three to seven villains singlehanded. I've written thirty-two books by now – and of course they're all exactly the same really, as Monsieur Poirot seems to have noticed – but nobody else has; and I only regret one thing, making my detective a Finn. I don't really know anything about Finns and I'm always getting letters from Finland pointing out something impossible that he's said or done. They seem to read detective stories a good deal in Finland. I suppose it's the long winters with no daylight. In Bulgaria and Rumania they don't seem to read at all. I'd have done better to have made him a Bulgarian,' She broke off.
'I'm so sorry. I'm talking shop. And this is a real murder.' Her face lighted up. 'What a good idea it would be if none of them had murdered him. If he'd asked them all, and then quietly committed suicide just for the fun of making a schemozzle.'
Poirot nodded approvingly. 'An admirable solution. So neat. So ironic. But alas, Mr. Shaitana was not that sort of man. He was very fond of life.'
