'That's your solution?'

'Well, if it wasn't natural for her to behave in that way, she must have been "putting on an act" as people say, and that means that somebody paid her to do what she did.'

'And you know who that somebody was?'

'Oh, I think so. Money again, I'm afraid. And I've always noticed that gentlemen always tend to admire the same type.'

'Now I'm out of my depth.'

'No, no, it all hangs together. Harry Laxton admired Bella Edge, a dark, vivacious type. Your niece Clarice was the same. But the poor little wife was quite a different type - fair-haired and clinging - not his type at all. So he must have married her for her money. And murdered her for her money, too!'

'You use the word "murder"?'

'Well, he sounds the right type. Attractive to women and quite unscrupulous. I suppose he wanted to keep his wife's money and marry your niece. He may have been seen talking to Mrs Edge. But I don't fancy he was attached to her any more. Though I dare say he made the poor woman think he was, for ends of his own. He soon had her well under his thumb, I fancy.'

'How exactly did he murder her, do you think?'

Miss Marple stared ahead of her for some minutes with dreamy blue eyes.

'It was very well timed - with the baker's van as witness. They could see the old woman and, of course, they'd put down the horse's fright to that. But I should imagine, myself, that an air gun, or perhaps a catapult. Yes, just as the horse came through the gates. The horse bolted, of course, and Mrs Laxton was thrown.'

She paused, frowning.

"The fall might have killed her. But he couldn't be sure of that. And he seems the sort of man who would lay his plans carefully and leave nothing to chance. After all, Mrs Edge could get him something suitable without her husband knowing. Otherwise, why would Harry bother with her? Yes, I think he had some powerful drug handy, that could be administered before you arrived. After all, if a woman is thrown from her horse and has serious juries and dies without recovering consciousness, well - a doctor wouldn't normally be suspicious, would he? He'd put it down to shock or something.'

Doctor Haydock nodded.

'Why did you suspect?' asked Miss Marple.

'It wasn't any particular cleverness on my part,' said Doctor Haydock. 'It was just the trite, well-known that a murderer is so pleased with his cleverness that he doesn't take proper precautions. I was just saying a few consolatory words to the bereaved husband - and feeling damned sorry for the fellow, too - when he flung himself down on the settee to do a bit of play-acting and a hypodermic syringe fell out of his pocket.

'He snatched it up and looked so scared that I began to think. Harry Laxton didn't drug; he was in perfect health; what was he doing with a hypodermic syringe? I did the autopsy with a view to certain possibilities. I found strophanthin. The rest was easy. There was strophanthin in Laxton's possession, and Bella Edge, questioned by the police, broke down and admitted to having got it for him. And finally old Mrs Murgatroyd confessed that it was Harry Laxton who had put her up to the cursing stunt.'

'And your niece got over it?'

'Yes, she was attracted by the fellow, but it hadn't gone far.'

The doctor picked up his manuscript.

'Full marks to you. Miss Marple - and full marks to me for my prescription. You're looking almost yourself again.'

Tape Measure Murder

Miss Politt took hold of the knocker and rapped politely on the cottage door. After a discreet interval she knocked again. The parcel under her left arm shifted a little as she did so, and she readjusted it. Inside the parcel was Mrs. Spenlow's new green winter dress, ready for fitting. From Miss Politt's left hand dangled a bag of black silk, containing a tape measure, a pincushion, and a large, practical pair of scissors.

Miss Politt was tall and gaunt, with a sharp nose, pursed lips, and a meager iron-grey hair. She hesitated before using the knocker for the third time. Glancing down the street, she saw a figure rapidly approaching. Miss Hartnell, jolly, weather-beaten, fifty-five, shouted out in her usual loud bass voice, 'Good afternoon, Miss Politt!'

The dressmaker answered, 'Good afternoon, Miss Hartnell.' Her voice was excessively thin and genteel in its accents. She had started life as a lady's maid. 'Excuse me,' she went on, 'but do you happen to know if by any chance Mrs. Spenlow isn't at home?'

'Not the least idea,' said Miss Hartnell.

'It's rather awkward, you see. I was to fit on Mrs. Spenlow's new dress this afternoon. Three-thirty, she said.'

Miss Hartnell consulted her wrist watch. 'It's a little past the half-hour now.'

'Yes. I have knocked three time, but there doesn't seem to be any answer, so I was wondering if perhaps Mrs. Spenlow might have gone out and forgotten. She doesn't forget appointments as a rule, and she wants the dress to wear the day after tomorrow.'

Miss Hartnell entered the gate and walked up the path to join Miss Politt outside the door of Laburnam Cottage.

'Why doesn't Gladys answer the door?' she demanded. 'Oh, no, of course, it's Thursday - Gladys's day out. I expect Mrs. Spenlow has fallen asleep. I don't expect you've made enough noise with this thing.'

Seizing the knocker, she executed a deafening rat-a-tat-tat and, in addition, thumped upon the panels of the door. She also called out in a stentorian voice: 'What ho, within there!'

There was no response.

Miss Politt murmured, 'Oh, I think Mrs. Spenlow must have forgotten and gone out. I'll call round some other time.' She began edging away down the path.

'Nonsense,' said Miss Hartnell firmly. 'She can't have gone out. I'd have met her. I'll just take a look through the windows and see if I can find any signs of life.'

She laughed in her usual hearty manner, to indicate that it was a joke, and applied a perfunctory glance to the nearest windowpane - perfunctory because she knew quite well that the front room was seldom used, Mr. and Mrs. Spenlow preferring the small back sitting room.

Perfunctory as it was, though, it succeeded in its object. Miss Hartnell, it is true, saw no signs of life. On the contrary, she saw, through the window, Mrs. Spenlow lying on the hearthrug - dead.

'Of course,' said Miss Hartnell, telling the story afterward, 'I managed to keep my head. That Politt creature wouldn't have had the least idea of what to do. 'Got to keep our heads,' I said to her. 'You stay here and I'll go for Constable Palk.' She said something about not wanting to be left, but I paid no attention at all. One has to be firm with that sort of person. I've always found they enjoy making a fuss. So I was just going off when, at that very moment, Mr. Spenlow came round the corn er of the house.'

Here Miss Hartnell made a significant pause. It enabled her audience to ask breathlessly, 'Tell me, how did he look?'

Miss Hartnell would then go on: 'Frankly, I suspected something at once! He was far too calm. He didn't seem surprised in the least. And you may say what you like, it isn't natural for a man to hear that his wife is dead and display no emotion what ever.'

Everybody agreed with this statement.

The police agreed with it too. So suspicious did they consider Mr. Spenlow's detachment that they lost no time in ascertaining how that gentleman was situated as a result of his wife's death. When they discovered that Mrs. Spenlow had been the money ed partner, and that her money went to her husband under a will made soon after their marriage, they were more suspicious than ever.

Miss Marple, that sweet-faced (and some said vinegar-tongued) elderly spinster who lived in the house next to the rectory, was interviewed very early - within half an hour of the discovery of the crime. She was approached by Police Constable Palk, importantly thumbing a notebook. 'If you don't mind, ma'am, I've a few questions to ask you.'
