‘Why, like this,’ said Irene very thoughtfully. ‘You would open the door of the room and find you were walking about on wallpaper with pictures hanging on it. (I’ll do the pictures for you.) Then one side of the room where the window is would be whitewashed as if it was a ceiling and the window would be the skylight. The opposite side would be the floor; and you would have the furniture screwed on to it. The other walls, including the one which would be the ceiling in an ordinary room, would be covered with wallpaper and more pictures and a bookcase. It would all be sideways, you see: you’d enter through the wall, and the room would be at right angles to you; ceiling on the left, floor on the right, or vice versa. It would give you a perfectly new perception of the world. You would see everything from a new angle, which is what we want so much in life nowadays. Don’t you think so?’

Irene’s speech was distinct and clear cut, she walked up and down the garden-room with a firm unwavering step, and Lucia put from her the uneasy suspicion that her dinner had gone to her head.

‘It would be most delightful,’ she said, ‘but slightly too experimental for me.’

‘And then, you see,’ continued Irene, ‘how useful it would be if somebody tipsy came in. It would make him sober at once, for tipsy people see everything crooked, and so your sideways-room, being crooked, would appear to him straight, and so he would be himself again. Just like that.’

‘That would be splendid,’ said Lucia, ‘but I can’t provide a room where tipsy people could feel sober again. The house isn’t big enough.’

Irene sat down by her, and passionately clasped one of her hands.

‘Lucia, you’re too adorable,’ she said. ‘Nothing defeats you. I’ve been talking the most abject nonsense, though I do think that there may be something in it, and you remain as calm as the moon which I hope will rise over the marsh before long, unless the almanack in which I looked it out is last year’s. Don’t tell anybody else about the sideways-room, will you, or they might think I was drunk. Let it be our secret, darling.’

Lucia wondered for a moment if she ought to allow Irene to spend the night on the marsh, but she was perfectly capable of coherent speech and controlled movements, and possibly the open air might do her good.

‘Not a soul shall know, dear,’ she said. ‘And now if you’re really going to paint the moon, you had better start. You feel quite sure you can manage it, don’t you?’
