Miss Marple paused, a little out of breath.

Jane Helier leant forward and said, ‘But the blue geranium, and the other flowers?’

‘Nurses always have litmus paper, don’t they?’ said Miss Marple, ‘for—well, for testing. Not a very pleasant subject. We won’t dwell on it. I have done a little nursing myself.’ She grew delicately pink. ‘Blue turns red with acids, and red turns blue with alkalis. So easy to paste some red litmus over a red flower—near the bed, of course. And then, when the poor lady used her smelling-salts, the strong ammonia fumes would turn it blue. Really most ingenious. Of course, the geranium wasn’t blue when they first broke into the room—nobody noticed it till afterwards. When nurse changed the bottles, she held the Sal Ammoniac against the wallpaper for a minute, I expect.’

‘You might have been there, Miss Marple,’ said Sir Henry.

‘What worries me,’ said Miss Marple, ‘is poor Mr Pritchard and that nice girl, Miss Instow. Probably both suspecting each other and keeping apart—and life so very short.’

She shook her head.

‘You needn’t worry,’ said Sir Henry. ‘As a matter of fact I have something up my sleeve. A nurse has been arrested on a charge of murdering an elderly patient who had left her a legacy. It was done with cyanide of potassium substituted for smelling-salts. Nurse Copling trying the same trick again. Miss Instow and Mr Pritchard need have no doubts as to the truth.’

‘Now isn’t that nice?’ cried Miss Marple. ‘I don’t mean about the new murder, of course. That’s very sad, and shows how much wickedness there is in the world, and that if once you give way—which reminds me I must finish my little conversation with Dr Lloyd about the village nurse.’

The Call of Wings

Silas Hamer heard it first on a wintry night in February. He and Dick Borrow had walked from a dinner given by Bernard Seldon, the nerve specialist. Borrow had been unusually silent, and Silas Hamer asked him with some curiosity what he was thinking about. Borrow’s answer was unexpected.

‘I was thinking, that of all these men tonight, only two amongst them could lay claim to happiness. And that these two, strangely enough, were you and I!’

The word ‘strangely’ was apposite, for no two men could be more dissimilar than Richard Borrow, the hard working East-end parson, and Silas Hamer, the sleek complacent man whose millions were a matter of household knowledge.

‘It’s odd, you know,’ mused Borrow, ‘I believe you’re the only contented millionaire I’ve ever met.’

Hamer was silent a moment. When he spoke his tone had altered.

‘I used to be a wretched shivering little newspaper boy. I wanted then—what I’ve got now!—the comfort and the luxury of money, not its power. I wanted money, not to wield as a force, but to spend lavishly—on myself! I’m frank about it, you see. Money can’t buy everything, they say. Very true. But it can buy everything I want—therefore I’m satisfied. I’m a materialist, Borrow, out and out a materialist!’
