‘I remember Jean rather startled me with what she said next. She said, “Well, that might be all for the best, mightn’t it?” And she said it so coolly, in so matter-of-fact a tone that I was really—well, shocked. Of course I know it’s done nowadays—to be brutal and outspoken; but I never get used to it. Jean smiled at me rather oddly and said, “You don’t like my saying that—but it’s true. What use is Mrs Pritchard’s life to her? None at all; and it’s hell for George Pritchard. To have his wife frightened out of existence would be the best thing that could happen to him.” I said, “George is most awfully good to her always.” And she said, “Yes, he deserves a reward, poor dear. He’s a very attractive person, George Pritchard. The last nurse thought so—the pretty one—what was her name? Carstairs. That was the cause of the row between her and Mrs P.”

‘Now I didn’t like hearing Jean say that. Of course one had wondered—’

Mrs Bantry paused significantly.

‘Yes, dear,’ said Miss Marple placidly. ‘One always does. Is Miss Instow a pretty girl? I suppose she plays golf?’

‘Yes. She’s good at all games. And she’s nice-looking, attractive-looking, very fair with a healthy skin, and nice steady blue eyes. Of course we always have felt that she and George Pritchard—I mean if things had been different—they are so well suited to one another.’

‘And they were friends?’ asked Miss Marple.

‘Oh yes. Great friends.’

‘Do you think, Dolly,’ said Colonel Bantry plaintively, ‘that I might be allowed to go on with my story?’

‘Arthur,’ said Mrs Bantry resignedly, ‘wants to get back to his ghosts.’

‘I had the rest of the story from George himself,’ went on the Colonel. ‘There’s no doubt that Mrs Pritchard got the wind up badly towards the end of the next month. She marked off on a calendar the day when the moon would be full, and on that night she had both the nurse and then George into her room and made them study the wallpaper carefully. There were pink hollyhocks and red ones, but there were no blue amongst them. Then when George left the room she locked the door—’

‘And in the morning there was a large blue hollyhock,’ said Miss Helier joyfully.

‘Quite right,’ said Colonel Bantry. ‘Or at any rate, nearly right. One flower of a hollyhock just above her head had turned blue. It staggered George; and of course the more it staggered him the more he refused to take the thing seriously. He insisted that the whole thing was some kind of practical joke. He ignored the evidence of the locked door and the fact that Mrs Pritchard discovered the change before anyone—even Nurse Copling—was admitted.

‘It staggered George; and it made him unreasonable. His wife wanted to leave the house, and he wouldn’t let her. He was inclined to believe in the supernatural for the first time, but he wasn’t going to admit it. He usually gave in to his wife, but this time he wouldn’t. Mary was not to make a fool of herself, he said. The whole thing was the most infernal nonsense.
