The Thirteen Problems

'I always explain things so badly. What I mean is that when Dr Lloyd described the two ladies first, he didn't know which was which, and I don't suppose anyone else in the hotel did. They would have, of course, after a day or so, but the very next day one of the two was drowned, and if the one who was left said she was Miss Barton, I don't suppose it would ever occur to anyone that she mightn't be.'

'You think - Oh! I see,' said Sir Henry slowly.

'It's the only natural way of thinking of it. Dear Mrs Bantry began that way just now. Why should the rich employer kill the humble companion? It's so much more likely to be the other way about I mean - that's the way things happen.'

'Is it?' said Sir Henry. 'You shock me.'

'But of course,' went on Miss Marple, 'she would have to wear Miss Barton's clothes, and they would probably be a little tight on her, so that her general appearance would look as though she had got a little fatter. That's why I asked that question. A gentleman would be sure to think it was the lady who had got fatter, and not the clothes that had got smaller - though that isn't quite the right way of putting it.'

'But if Amy Durrant killed Miss Barton, what did she gain by it?' asked Mrs Bantry. 'She couldn't keep up the deception for ever.'

'She only kept it up for another month or so,' pointed out Miss Marple. 'And during that time I expect she travelled, keeping away from anyone who might know her. That's what I meant by saying that one lady of a certain age looks so like another. I don't suppose the different photograph on her passport was ever noticed - you know what passports are. And then in March, she went down to this Cornish place and began to act queerly and draw attention to herself so that when people found her clothes on the beach and read her last letter they shouldn't think of the commonsense conclusion.'

'Which was?' asked Sir Henry.

'No body,' said Miss Marple firmly. 'That's the thing that would stare you in the face, if there weren't such a lot of red herrings to draw you off the trail - including the suggestion of foul play and remorse. No body. That was the real significant fact.'

'Do you mean - ' said Mrs Bantry - 'do you mean that there wasn't any remorse? That there wasn't - that she didn't drown herself?'

'Not she!' said Miss Marple. 'It's just Mrs Trout over again. Mrs Trout was very good at red herrings, but she met her match in me. And I can see through your remorse-driven Miss Barton. Drown herself? Went off to Australia, if I'm any good at guessing.'

'You are, Miss Marple,' said Dr Lloyd. 'Undoubtedly you are. Now it again took me quite by surprise. Why, you could have knocked me down with a feather that day in Melbourne.'

'Was that what you spoke of as a final coincidence?'

Dr Lloyd nodded.

'Yes, it was rather rough luck on Miss Barton - or Miss Amy Durrant - whatever you like to call her. I became a ship's doctor for a while, and landing in Melbourne, the first person I saw as I walked down the street was the lady I thought had been drowned in Cornwall. She saw the game was up as far as I was concerned, and she did the bold thing - took me into her confidence. A curious woman, completely lacking, I suppose, in some moral sense. She was the eldest of a family of nine, all wretchedly poor. They had applied once for help to their rich cousin in England and been repulsed, Miss Barton having quarrelled with their father. Money was wanted desperately, for the three youngest children were delicate and wanted expensive medical treatment. Amy Barton then and there seems to have decided on her plan of cold-blooded murder. She set out for England, working her passage over as a children's nurse. She obtained the situation of companion to Miss Barton, calling herself Amy Durrant. She engaged a room and put some furniture into it so as to create more of a personality for herself. The drowning plan was a sudden inspiration. She had been waiting for some opportunity to present itself. Then she staged the final scene of the drama and returned to Australia, and in due time she and her brothers and sisters inherited Miss Barton's money as next of kin.'

'A very bold and perfect crime,' said Sir Henry. 'Almost the perfect crime. If it had been Miss Barton who had died in the Canaries, suspicion might attach to Amy Durrant and her connection with the Barton family might have been discovered; but the change of identity and the double crime, as you may call it, effectually did away with that. Yes, almost the perfect crime.'

'What happened to her?' asked Mrs Bantry. 'What did you do in the matter, Dr Lloyd?'
