Miss Marple's final cases

'Oh, poor dear, she has been very much under the weather lately. She can't help it, of course, but it really makes things a little difficult sometimes. Wanting certain things cooked and then, when they come, saying she can't eat now - and then wanting them again half an hour later and everything spoiled and having to be done again. It makes, of course, a lot of work - but fortunately Mary does not seem to mind at all. She's used to waiting on invalids, she says, and understands them. It is such a comfort.'

'Dear me,' said Miss Marple. 'You are fortunate.'

'Yes, indeed. I really feel Mary has been sent to us as an answer to prayer.'

'She sounds to me,' said Miss Marple, 'almost too good to be true. I should - well, I should be a little careful if I were you.'

Lavinia Skinner failed to perceive the point of this remark. She said, 'Oh! I assure you I do all I can to make her comfortable. I don't know what I should do if she left.'

'I don't expect she'll leave until she's ready to leave,' said Miss Marple and stared very hard at her hostess.

Miss Lavinia said, 'If one has no domestic worries, it takes such a load off one's mind, doesn't it? How is your little Edna shaping?'

'She's doing quite nicely. Not much ahead, of course. Not like your Mary. Still, I do know all about Edna because she's a village girl.'

As she went out into the hall she heard the invalid's voice fretfully raised. 'This compress has been allowed to get quite dry - Doctor Allerton particularly said moisture continually renewed. There, there, leave it. I want a cup of tea and a boiled egg - boiled only three minutes and a half, remember, and send Miss Lavinia to me.'

The efficient Mary emerged from the bedroom and, saying to Lavinia, 'Miss Emily is asking for you, madam,' proceeded to open the door for Miss Marple, helping her into her coat and handing her her umbrella in the most irreproachable fashion.

Miss Marple took the umbrella, dropped it, tried to pick it up, and dropped her bag, which flew open. Mary politely retrieved various odds and ends - a handkerchief, an engagement book, an old-fashioned leather purse, two shillings, three pennies, and a striped piece of peppermint rock.

Miss Marple received the last with some signs of confusion.

'Oh, dear, that must have been Mrs Clement's little boy. He was sucking it, I remember, and he took my bag to play with. He must have put it inside. It's terribly sticky, isn't it?'

'Shall I take it, madam?'

'Oh, would you? Thank you so much.'

Mary stooped to retrieve the last item, a small mirror, upon recovering which Miss Marple exclaimed fervently, 'How lucky, now, that that isn't broken.'

She thereupon departed, Mary standing politely by the door holding a piece of striped rock with a completely expressionless face.

For ten days longer St Mary Mead had to endure hearing of the excellencies of Miss Lavinia and Miss Emily's treasure.

On the eleventh day, the village awoke to its big thrill.

Mary, the paragon, was missing! Her bed had not been slept in, and the front door was found ajar. She had slipped out quietly during the night.

And not Mary alone was missing! Two brooches and five rings of Miss Lavinia's; three rings, a pendant, a bracelet, and four brooches of Miss Emily's were missing, also!

It was the beginning of a chapter of catastrophe.

Young Mrs Devereux had lost her diamonds which she kept in a unlocked drawer and also some valuable furs given to her as a wedding present. The judge and his wife also had had jewellery taken and a certain amount of money. Mrs Carmichael was the greatest sufferer. Not only had she some very valuable jewels but she also kept in the flat a large sum of money which had gone. It had been Janet's evening out, and her mistress was in the habit of walking round the gardens at dusk calling to the birds and scattering crumbs. It seemed clear that Mary, the perfect maid, had had keys to fit all the flats!

There was, it must be confessed, a certain amount of ill-natured pleasure in St Mary Mead. Miss Lavinia had boasted so much of her marvellous Mary.

'And all the time, my dear, just a common thief!'

Interesting revelations followed. Not only had Mary disappeared into the blue, but the agency who had provided her and vouched for her credentials was alarmed to find that the Mary Higgins who had applied to them and whose references they had taken up had, to all intents and purposes, never existed. It was the name of a bona fide servant who had lived with the bona fide sister of a dean, but the real Mary Higgins was existing peacefully in a place in Cornwall.

'Damned clever, the whole thing,' Inspector Slack was forced to admit. 'And, if you ask me, that woman works with a gang. There was a case of much the same kind in Northumberland a year ago. Stuff was never traced, and they never caught her. However, we'll do better than that in Much Benham!'

Inspector Slack was always a confident man.
