all over the world. Then they bought this house somewhere—I think it was abroad but I can’t remember. And then there were suddenly accounts of this case in the papers. Whether somebody else had killed them or whether they’d been assassinated or something, or whether they killed each other. I think it was a revolver that had been in the house for ages and—well, I’d better tell you as much as I can remember.’
Pulling herself slightly together, Mrs Oliver managed to give Poirot a more or less clear résumé of what she had been told. Poirot from time to time checked on a point here or there.
‘But why?’ he said finally, ‘why should this woman want to know this?’
‘Well, that’s what I want to find out,’ said Mrs Oliver. ‘I could get hold of Celia, I think. I mean, she still lives in London. Or perhaps it’s Cambridge she lives in, or Oxford—I think she’s got a degree and either lectures here or teaches somewhere, or does something like that. And—very modern, you know. Goes about with long-haired people in queer clothes. I don’t think she takes drugs. She’s quite all right and—just very occasionally I hear from her. I mean, she sends a card at Christmas and things like that. Well, one doesn’t think of one’s god-children all the time, and she’s quite twenty-five or -six.’
‘Not married?’
‘No. Apparently she is going to marry—or that is the idea—Mrs—What’s the name of that woman again?—oh yes, Mrs Brittle—no—Burton-Cox’s son.’
‘And Mrs Burton-Cox does not want her son to marry this girl because her father killed her mother or her mother killed her father?’
‘Well, I suppose so,’ said Mrs Oliver. ‘It’s the only thing I can think. But what does it matter which? If one of your parents killed the other, would it really matter to the mother of the boy you were going to marry, which way round it was?’
‘That is a thing one might have to think about,’ said Poirot. ‘It is—yes, you know it is quite interesting. I do not mean it is very interesting about Sir Alistair Ravenscroft or Lady Ravenscroft. I seem to remember vaguely—oh, some case like this one, or it might not have been the same one. But it is very strange about Mrs Burton-Cox. Perhaps she is a bit touched in the head. Is she very fond of her son?’
‘Probably,’ said Mrs Oliver. ‘Probably she doesn’t want him to marry this girl at all.’
‘Because she may have inherited a predisposition to murder the man she marries—or something of that kind?’
‘How do I know?’ said Mrs Oliver. ‘She seems to think that I can tell her, and she’s really not told me enough, has she? But why, do you think? What’s behind it all? What does it mean?’
‘It would be almost interesting to find out,’ said Poirot.
‘Well, that’s why I’ve come to you,’ said Mrs Oliver. ‘You like finding out things. Things that you can’t see the reason for at first. I mean, that nobody can see the reason for.’
‘Do you think Mrs Burton-Cox has any preference?’ said Poirot.
‘You mean that she’d rather the husband killed the wife, or the wife killed the husband? I don’t think so.’
‘Well,’ said Poirot, ‘I see your dilemma. It is very intriguing. You come home from a party. You’ve been asked to do something that is very difficult, almost impossible, and—you wonder what is the proper way to deal with such a thing.’
‘Well, what would you think is the proper way?’ said Mrs Oliver.
‘It is not easy for me to say,’ said Poirot. ‘I’m not a woman. A woman whom you do not really know, whom you had met at a party, has put this problem to you, asked you to do it, giving no discernible reason.’
‘Right,’ said Mrs Oliver. ‘Now what does Ariadne do? What does A do, in other words, if you were reading this as a problem in a newspaper?’
‘Well, I suppose,’ said Poirot, ‘there are three things that A could do. A could write a note to Mrs Burton-Cox and say, “I’m very sorry but I really feel I cannot oblige you in this matter,” or whatever words you like to put. B. You get into touch with your goddaughter and you tell her what has been asked of you by the mother of the boy, or the young man, or whatever he is, whom she is thinking of marrying. You will find out from her if she is really thinking of marrying this young man. If so, whether she has any idea or whether the young man has said anything to her about what his mother has got in her head. And there will be other interesting points, like finding out what this girl thinks of the mother of the young man she wants to marry. The third thing you could do,’ said Poirot, ‘and this really is what I firmly advise you to do, is …’
‘I know,’ said Mrs Oliver, ‘one word.’
‘Nothing,’ said Poirot.
‘Exactly,’ said Mrs Oliver. ‘I know that is the simple and proper thing to do. Nothing. It’s darned cheek to go and tell a girl who’s my goddaughter what her future mother-in-law is going about saying, and asking people. But—’
‘I know,’ said Poirot, ‘it is human curiosity.’
‘I want to know why that odious woman came and said what she did to me,’ said Mrs Oliver. ‘Once I know that I could relax and forget all about it. But until I know that …’
‘Yes,’ said Poirot, ‘you won’t sleep. You’ll wake up in the night and, if I know you, you will have the most extraordinary and extravagant ideas which presently, probably, you will be able to make into a most attractive crime story. A whodunit—a thriller. All sorts of things.’
‘Well, I suppose I could if I thought of it that way,’ said Mrs Oliver. Her eyes flashed slightly.
‘Leave it alone,’ said Poirot. ‘It will be a very difficult plot to undertake. It seems as though there could be no good reason for this.’
‘But I’d like to make sure that there is no good reason.’
‘Human curiosity,’ said Poirot. ‘Such a very interesting thing.’ He sighed. ‘To think what we owe to it throughout history. Curiosity. I don’t know who invented curiosity. It is said to be usually associated with the cat. Curiosity killed the cat. But I should say really that the Greeks were the inventors of curiosity. They wanted to know. Before them, as far as I can see, nobody wanted to know much. They just wanted to know what the rules of the country they were living in were, and how they could avoid having their heads cut off or being impaled on spikes or something disagreeable happening to them. But they either obeyed or disobeyed. They didn’t want to know why. But since then a lot of people have wanted to know why and all sorts of things have happened because of that. Boats, trains, flying machines and atom bombs and penicillin and cures for various illnesses. A little boy watches his mother’s kettle raising its lid because of the steam. And the next thing we know is we have railway trains, leading on in due course to railway strikes and all that. And so on and so on.’
‘Just tell me,’ said Mrs Oliver, ‘do you think I’m a terrible nosey-parker?’
‘No, I don’t,’ said Poirot. ‘On the whole I don’t think you are a woman of great curiosity. But I can quite see you getting in a het-up state at a literary party, busy defending yourself against too much kindness, too much praise.
