“And so Bunny died in her sleep, quite happily, and Charlotte felt safe again. But she missed Dora Bunner—she missed her affection and her loyalty, she missed being able to talk to her about the old days … She cried bitterly the day I came up with that note from Julian—and her grief was quite genuine. She’d killed her own dear friend….”

“That’s horrible,” said Bunch. “Horrible.”

“But it’s very human,” said Julian Harmon. “One forgets how human murderers are.”

“I know,” said Miss Marple. “Human. And often very much to be pitied. But very dangerous, too. Especially a weak kindly murderer like Charlotte Blacklock. Because, once a weak person gets really frightened, they get quite savage with terror and they’ve no self-control at all.”

“Murgatroyd?” said Julian.

“Yes, poor Miss Murgatroyd. Charlotte must have come up to the cottage and heard them rehearsing the murder. The window was open and she listened. It had never occurred to her until that moment that there was anyone else who could be a danger to her. Miss Hinchcliffe was urging her friend to remember what she’d seen and until that moment Charlotte hadn’t realized that anyone could have seen anything at all. She’d assumed that everybody would automatically be looking at Rudi Scherz. She must have held her breath outside the window and listened. Was it going to be all right? And then, just as Miss Hinchcliffe rushed off to the station Miss Murgatroyd got to a point which showed that she had stumbled on the truth. She called after Miss Hinchcliffe: ‘She wasn’t there.…’

“I asked Miss Hinchcliffe, you know, if that was the way she said it … Because if she’d said ‘She wasn’t there’ it wouldn’t have meant the same thing.”

“Now that’s too subtle a point for me,” said Craddock.

Miss Marple turned her eager pink and white face to him.

“Just think what’s going on in Miss Murgatroyd’s mind … One does see things, you know, and not know one sees them. In a railway accident once, I remember noticing a large blister of paint at the side of the carriage. I could have drawn it for you afterwards. And once, when there was a flying bomb in London—splinters of glass everywhere—and the shock—but what I remember best is a woman standing in front of me who had a big hole halfway up the leg of her stockings and the stockings didn’t match. So when Miss Murgatroyd stopped thinking and just tried to remember what she saw, she remembered a good deal.
