"What about Harper? Is he to be in on this?"

"It might be awkward for him to know too much. But there might be a hint from you. To watch certain persons, have them trailed, you know."

Sir Henry said slowly, "Yes, that would meet the case."

Superintendent Harper looked piercingly at Sir Henry Clithering. "Let's get this quite clear, sir. You're giving me a hint?"

Sir Henry said, "I'm informing you of what my friend has just informed me. He didn't tell me in confidence that he purposes to visit a solicitor in Danemouth tomorrow for the purpose of making a new will."

The superintendent's bushy eyebrows drew downward over his steady eyes. He said, "Does Mr. Conway Jefferson propose to inform his son-in-law and daughter-in-law of that fact?"

"He intends to tell them about it this evening."

"I see." The superintendent tapped his desk with a penholder. He repeated again, "I see." Then the piercing eyes bored once more into the eyes of the other man. Harper said, "So you're not satisfied with the case against Basil Blake?"

"Are your [missing text]

The superintendent's mustaches quivered. He said, "Is Miss Marple?" The two men looked at each other. Then Harper said, "You can leave it to me. I'll have men detailed. There will be no funny business, I can promise you that."

Sir Henry said, "There is one more thing. You'd better see this." He unfolded a slip of paper and pushed it across the table.

This time the superintendent's calm deserted him. He whistled. "So that's it, is it? That puts an entirely different complexion on the matter. How did you come to dig up this?"

"Women," said Sir Henry, "are eternally interested in marriages."

"Especially," said the superintendent, "elderly single women!"

Conway Jefferson looked up as his friend entered. His grim face relaxed into a smile. He said, "Well, I told 'em. They took it very well."

"What did you say?"

[missing text] to endow a hostel for young girls working as professional dancers in London. Damned silly way to leave your money. Surprised they swallowed it as though I'd do a thing like that." He added meditatively, "You know, I made a fool of myself over that girl. Must be turning into a silly old man. I can see it now. She was a pretty kid, but most of what I saw in her I put there myself. I pretended she was another Rosamund. Same coloring, you know. But not the same heart or mind. Hand me that paper; rather an interesting bridge problem."

Sir Henry went downstairs. He asked a question of the porter.

"Mr. Gaskell, sir? He's just gone off in his car. Had to go to London." "Oh, I see. Is Mrs. Jefferson about?" "Mrs. Jefferson, sir, has just gone up to bed." Sir Henry looked into the lounge and through to the ballroom. In the lounge Hugo McLean was doing a crossword puzzle and frowning a good deal over it. In the ballroom, Josie was smiling valiantly into the face of a stout, perspiring man as her nimble feet avoided his destructive tread. The stout man was clearly enjoying his dance. Raymond, graceful and weary, was dancing with an anemic-looking girl with adenoids, dull brown hair and an expensive and exceedingly unbecoming dress. Sir Henry said under his breath, "And so to bed," and went upstairs.

It was three o'clock. The wind had fallen, the moon was shining over the quiet sea. In Conway Jefferson's room there was no sound except his own heavy breathing as he lay half propped up on pillows. There was no breeze to stir the curtains at the window, but they stirred. For a moment they parted and a figure was silhouetted against the moonlight. Then they fell back into place. Everything was quiet again, but there was someone else inside the room. Nearer and nearer to the bed the intruder stole. The deep breathing on the pillow did not relax. There was no sound, or hardly any sound. A finger and thumb were ready to pick up a fold of skin; in the other hand the hypodermic was ready. And then, suddenly, out of the shadows a hand came and closed over the hand that held the needle; the other arm held the figure in an iron grasp. An unemotional voice the voice of the law, said, "No, you don't! I want that needle!" The light switched on, and from his pillows Conway Jefferson looked grimly at the murderer of Ruby Keene.

Sir Henry Clithering said, "Speaking as Watson, I want to know your methods. Miss Marple."

Superintendent Harper said, "I'd like to know what put you on to it first."

Colonel Melchett said, "You've done it again, by Jove, Miss Marple. I want to hear all about it from the beginning."

Miss Marple smoothed the pure silk of her best evening gown. She flushed and smiled and looked very self-conscious. She said, "I'm afraid you'll think my 'methods,' as Sir Henry calls them, are terribly amateurish. The truth is, you see, that most people, and I don't exclude policemen, are far too trusting for this wicked world. They believe what is told them. I never do. I'm afraid I always like to prove a thing for myself."

"That is the scientific attitude," said Sir Henry.

"In this case," continued Miss Marple, "certain things were taken for granted from the first, instead of just confining oneself to the facts. The facts, as I noted them, were that the victim was quite young and that she bit her nails and that her teeth stuck out a little as young girls' so often do if not corrected in time with a plate, and children are very naughty about their plates and take them out when their elders aren't looking."

"But that is wandering from the point. Where was I? Oh, yes, looking down at the dead girl and feeling sorry, because it is always sad to see a young life cut short, and thinking that whoever had done it was a very wicked person. Of course it was all very confusing, her being found in Colonel Bantry's library, altogether too like a book to be true. In fact, it made the wrong pattern. It wasn't, you see, meant, which confused us a lot. The real idea had been to plant the body on poor young Basil Blake, a much more likely person, and his action in putting it in the colonel's library delayed things considerably and must have been a source of great annoyance to the real murderer. Originally, you see, Mr. Blake would have been the first object of suspicion. They'd have made inquiries at Danemouth, found he knew the girl, then found he had tied himself up with another girl, and they'd have assumed that Ruby came to blackmail him or something like that, and that he'd strangled her in a fit of rage. Just an ordinary, sordid, what I call night-club type of crime!"

"But that, of course, all went wrong, and interest became focused much too soon on the Jefferson family to the great annoyance of a certain person."

"As I've told you, I've got a very suspicious mind. My nephew Raymond tells me in fun, of course, that I have a mind like a sink. He says that most Victorians have. All I can say is that the Victorians knew a good deal about human nature. As I say, having this rather insanitary - or surely sanitary? - mind, I looked at once at the money angle of it. Two people stood to benefit by this girl's death you couldn't get away from that. Fifty thousand pounds is a lot of money; especially when you are in financial difficulties, as both these people were. Of course they both seemed very nice, agreeable people; they didn't seem likely people, but one never can tell, can one?"

"Mrs. Jefferson, for instance. Everyone liked her. But it did seem clear that she had become very restless that summer and that she was tired of the life she led, completely dependent on her father-in-law. She knew, because the doctor had told her, that he couldn't live long, so that was all right, to put it callously, or it would have been all right if Ruby Keene hadn't come along. Mrs. Jefferson was passionately devoted to her son, and some women have a curious idea that crimes committed for the sake of their offspring are almost morally justified. I have come across that attitude once or twice in the village. "Well, 'twas all for Daisy, you see, miss," they say, and seem to think that that makes doubtful conduct quite all right. Very lax thinking."
