Agatha Christie - The Mirror Crack'd from Side to Side

'I don't see that you've got anything to tell,' said Cherry.

'Well, it was funny,' said Gladys, defiantly clinging to her favourite adjective.

'I think,' said Cherry, 'that you just want an excuse to go and talk to Mr Giuseppe – and you'd better be careful, my girl. You know what these wops are like! Affiliation orders all over the place. Hot-blooded and passionate, that's what these Italians are.'

Gladys sighed ecstatically.

Cherry looked at her friend's fat slightly spotted face and decided that her warnings were unnecessary. Mr Giuseppe, she thought, would have better fish to fry elsewhere.

'Aha!' said Dr Haydock, 'unravelling, I see.'

He looked from Miss Marple to a pile of fluffy white fleecy wool.

'You advised me to try unravelling if I couldn't knit,' said Miss Marple.

'You seem to have been very thorough about it.'

'I made a mistake in the pattern right at the beginning. That made the whole thing go out of proportion, so I've had to unravel it all. It's a very elaborate pattern, you see.'

'What are elaborate patterns to you? Nothing at all.'

'I ought really, I suppose, with my bad eyesight, to stick to plain knitting.'

'You'd find that very boring. Well, I'm flattered that you took my advice.'

'Don't I always take your advice, Doctor Haydock?'

'You do when it suits you,' said Dr Haydock.

'Tell me, Doctor, was it really knitting you had in mind when you gave me that advice?'

He met the twinkle in her eyes and twinkled back at her.

'How are you getting on with unravelling the murder?' he asked.

'I'm afraid my faculties aren't quite what they were,' said Miss Marple, shaking her head with a sigh.

'Nonsense,' said Dr Haydock. 'Don't tell me you haven't formed some conclusions.'

'Of course I have formed conclusions. Very definite ones.'

'Such as?' asked Haydock inquiringly.

'If the cocktail glass was tampered with that day – and I don't see quite how that could have been done -'

'Might have had the stuff ready in an eyedropper,' suggested Haydock.

'You are so professional,' said Miss Marple admiringly. 'But even then it seems to me so very peculiar that nobody saw it happen.'

'Murder should not only be done, but be seen done! Is that it?'

'You know exactly what I mean,' said Miss Marple.

'That was a chance the murderer had to take,' said Haydock.

'Oh quite so. I'm not disputing that for a moment. But there were, I have found by inquiry and adding up the persons, at least eighteen to twenty people on the spot. It seems to me that amongst twenty people somebody must have seen that action occur.'

Haydock nodded. 'One would think so, certainly. But obviously no one did.'

'I wonder,' said Miss Marple thoughtfully.

'What have you got in mind exactly?'

'Well, there are three possibilities. I'm assuming that at least one person would have seen something. One out of twenty. I think it's only reasonable to assume that.'

'I think you're begging the question,' said Haydock, 'and I can see looming ahead one of those terrible exercises in probability where six men have white hats and six men have black and you have to work it out by mathematics how likely it is that the hats will get mixed up and in what proportion. If you start thinking about things like that you would go round the bend. Let me assure you of that!'

'I wasn't thinking of anything like that,' said Miss Marple. 'I was just thinking of what is likely -'

'Yes,' said Haydock thoughtfully, 'you're very good at that. You always have been.'

'It is likely, you know,' said Miss Marple, 'that out of twenty people one at least should be an observant one.'

'I give in,' said Haydock. 'Let's have the three possibilities.'

'I'm afraid I'll have to put them in rather sketchily,' said Miss Marple. 'I haven't quite thought it out. Inspector Craddock, and probably Frank Cornish before him, will have questioned everybody who was there so the natural thing would be that whoever saw anything of the kind would have said so at once.'

'Is that one of the possibilities?'

'No, of course it isn't,' said Miss Marple, 'because it hasn't happened. What you have to account for is if one person did see something why didn't that person say so?'

'I'm listening.'

'Possibility One,' said Miss Marple, her cheeks going pink with animation. 'The person who saw it didn't realise what they had seen. That would mean, of course, that it would have to be rather a stupid person. Someone, let us say, who can use their eyes but not their brain. The sort of person who, if you asked them. 'Did you see anyone put anything in Marina Gregg's glass?" would answer, "Oh, no," but if you said "Did you see anyone put their hand over the top of Marina Gregg's glass" would say "Oh, yes, of course I did."'

Haydock laughed. 'I admit,' he said, 'that one never quite allows for the moron in our midst. All right, I grant you Possibility One. The moron saw it, the moron didn't grasp what the action meant. And the second possibility?'

'This one's far-fetched, but I do think it's just a possibility. It might have been a person whose action in putting something in a glass was natural.'

'Wait, wait, explain that a little more clearly.'

'It seems to me nowadays,' said Miss Marple, 'that people are always adding things to what they eat and drink. In my young days it was considered to be very bad manners to take medicines with one's meals. It was on a par with blowing your nose at the dinner table. It just wasn't done. If you had to take pills or capsules, or a spoonful of something, you went out of the room to do so. That's not the case now. When staying with my nephew Raymond, I observed some of his guests seemed to arrive with quite a quantity of little bottles of pills and tablets. They take them with food, or before food, or after food. They keep aspirins and such things in their handbags and take them the whole time – with cups of tea or with their after-dinner coffee. You understand what I mean?'

'Oh, yes,' said Dr Haydock, 'I've got your meaning now and it's interesting. You mean that someone -' he stopped. 'Let's have it in your own words.'

'I meant,' said Miss Marple, 'that it would be quite possible, audacious but possible, for someone to pick up that glass which as soon as it was in his or her hand, of course, would be assumed to be his or her own drink and to add whatever was added quite openly. In that case, you see, people wouldn't think twice of it.'

'He – or she – couldn't be sure of that, though,' Haydock pointed out.

'No,' agreed Miss Marple, 'it would be a gamble, a risk – but it could happen. And then,' she went on, 'there's the third possibility.'

'Possibility One, a moron,' said the doctor. 'Possibility Two, a gambler – what's Possibility Three?'

'Somebody saw what happened, and has held their tongue deliberately.'

Haydock frowned. 'For what reason?' he asked. 'Are you suggesting blackmail? If so -'

'If so,' said Miss Marple, 'it's a very dangerous thing to do.'

'Yes, indeed.' He looked sharply at the placid old lady with the white fleecy garment on her lap. 'Is the third possibility the one you consider the most probable one?'

'No,' said Miss Marple, 'I wouldn't go so far as that. I have, at the moment, insufficient grounds. Unless,' she added carefully, 'someone else gets killed.'

'Do you think someone else is going to get killed?'

'I hope not,' said Miss Marple, 'I trust and pray not. But it so often happens, Doctor Haydock. That's the sad and frightening thing. It so often happens.'

Ella put down the telephone receiver, smiled m herself and came out of the public telephone box. She was pleased with herself.
