Curtain

'A murder will shortly be committed here – here.'

Chapter 3

For a moment or two I stared at Poirot in dismay, then I reacted.

'No, it won't,' I said. 'You'll prevent that.'

Poirot threw me an affectionate glance.

'My loyal friend. How much I appreciate your faith in me. Tout de meme, I am not sure if it is justified in this case.'

'Nonsense. Of course you can stop it.'

Poirot's voice was grave as he said:

'Reflect a minute, Hastings. One can catch a murderer, yes. But how does one proceed to stop a murder?'

'Well, you – you – well, I mean – if you know beforehand -'

I paused rather feebly – for suddenly I saw the difficulties.

Poirot said:

'You see? It is not so simple. There are, in fact, only three methods. The first is to warn the victim. To put the victim on his or her guard. That does not always succeed, for it is unbelievably difficult to convince some people that they are in grave danger – possibly from someone near and dear to them. They are indignant and refuse to believe. The second course is to warn the murderer. To say, in language that is only slightly veiled: 'I know your intentions. If so-and-so dies, my friend, you will most surely hang.' That succeeds more often than the first method, but even there it is likely to fail. For a murderer, my friend, is more conceited than any creature on this earth. A murderer is always more clever than anyone else – no one will ever suspect him or her – the police will be utterly baffled, et cetera. Therefore he (or she) goes ahead just the same, and all you can have is the satisfaction of hanging them afterwards.' He paused and said thoughtfully:

'Twice in my life I have warned a murderer – once in Egypt, once elsewhere. In each case, the criminal was determined to kill… It may be so here.'

'You said there was a third method,' I reminded him.

'Ah yes. For that one needs the utmost ingenuity. You have to guess exactly how and when the blow is timed to fall and you have to be ready to step in at the exact psychological moment. You have to catch the murderer, if not quite red-handed, then guilty of the intention beyond any possible doubt.

'And that, my friend,' went on Poirot, 'is, I can assure you, a matter of great difficulty and delicacy, and I would not for a moment guarantee its success! I may be conceited, but I am not so conceited as that.'

'Which method do you propose to try here?'

'Possibly all three. The first is the most difficult.'

'Why? I should have thought it the easiest.'

'Yes, if you know the intended victim. But do you not realize, Hastings, that here I do not know the victim?'

'What?'

I gave vent to the exclamation without reflecting. Then the difficulties of the position began to dawn on me. There was, there must be, some link connecting this series of crimes, but we did not know what that link was. The motive, the vitally important motive, was missing. And without knowing that, we could not tell who was threatened.

Poirot nodded as he saw by my face that I was realizing the difficulties of the situation.

'You see, my friend, it is not so easy.'

'No,' I said. 'I see that. You have so far been able to find no connection between these varying cases?'

Poirot shook his head.

'Nothing.'

I reflected again. In the A.B.C. crimes, we had to deal with what purported to be an alphabetical series, though in actuality it had turned out to be something very different.

I asked:

'There is, you are quite sure, no far-fetched financial motive – nothing, for instance, like you found in the case of Evelyn Carlisle?'

'No. You may be quite sure, my dear Hastings, that financial gain is the first thing for which I look.'

That was true enough. Poirot has always been completely cynical about money.

I thought again. A vendetta of some kind? That was more in accordance with the facts. But even there, there seemed a lack of any connecting link. I recalled a story I had read of a series of purposeless murders – the clue being that the victims had happened to serve as members of a jury, and the crimes had been committed by a man whom they had condemned. It struck me that something of that kind would meet this case. I am ashamed to say that I kept the idea to myself. It would have been such a feather in my cap if I could go to Poirot with the solution.

Instead I asked:

'And now tell me, who is X?'

To my intense annoyance Poirot shook his head very decidedly.

'That, my friend, I do not tell.'

'Nonsense. Why not?'

Poirot's eyes twinkled.

'Because, mon cher, you are still the same old Hastings. You have still the speaking countenance. I do not wish, you see, that you should sit staring at X with your mouth hanging open, your face saying plainly: 'This – this that I am looking at is a murderer.''

'You might give me credit for a little dissimulation at need.'

'When you try to dissimulate, it is worse. No, no, mon ami, we must be very incognito, you and I. Then, when we pounce, we pounce.'

'You obstinate old devil,' I said. 'I've a good mind to -'

I broke off as there was a tap on the door. Poirot called, 'Come in,' and my daughter Judith entered.

I should like to describe Judith, but I've always been a poor hand at descriptions.

Judith is tall, she holds her head high, she has level dark brows and a very lovely line of cheek and jaw – severe in its austerity. She is grave and slightly scornful, and to my mind there has always hung about her a suggestion of tragedy.

Judith didn't come and kiss me – she is not that kind. She just smiled at me and said, 'Hullo, Father.'

Her smile was shy and a little embarrassed, but it made me feel that in spite of her undemonstrativeness she was pleased to see me.

'Well,' I said, feeling foolish as I so often do with the younger generation, 'I've got here.'

'Very clever of you, darling,' said Judith.

'I describe to him,' said Poirot, 'the cooking.'

'Is it very bad?' asked Judith.

'You should not have to ask that, my child. Is it that you think of nothing but the test tubes and the microscopes? Your middle finger, it is stained with methylene blue. It is not a good thing for your husband if you take no interest in his stomach.'

'I daresay I shan't have a husband.'

'Certainly you will have a husband. What did the bon Dieu create you for?'

'Many things, I hope,' said Judith.

'Le mariage first of all.'

'Very well,' said Judith. 'You shall find me a nice husband and I will look after his stomach very carefully.'

'She laughs at me,' said Poirot. 'Someday she will know how wise old men are.'

There was another tap on the door and Dr Franklin entered. He was a tall, angular young man of thirty-five,
