‘That’s right. Power. That’s the very thing we want.’ Clarice turned her eyes to Steerpike. Then she smoothed the shiny purple of her dress.

‘I rather liked them,’ she said.

Steerpike, wondering where on earth her thoughts had taken her, tilted his head on one side as though reflecting upon the truth in her remark, when Cora’s voice (like the body of a plaice translated into sound) asked:

‘You rather liked what?’

‘My convulsions,’ said Clarice earnestly. ‘When my left arm became starved for the first time. You remember, Cora, don’t you? When we had our first fits? I rather liked them.’

Cora rustled up to her and raised a forefinger in front of her sister’s face. ‘Clarice Groan,’ she said, ‘we finished talking about that long ago. We’re talking about Power now. Why can’t you follow what we’re talking about? You are always losing your place. I’ve noticed that.’

‘What about the Room of Roots?’ asked Steerpike with affected gaiety. ‘Why is it called the Room of Roots? I am most intrigued.’

‘Don’t you know?’ came their voices.

‘He doesn’t know,’ said Clarice. ‘You see how we’ve been forgotten. He didn’t know about our Room of Roots.’

Steerpike was not kept long in ignorance. He followed the two purple ninepins through the door, and after passing down a short passage, Cora opened a massive door at the far end whose hinges could have done with a gill of oil apiece, and followed by her sister entered the Room of Roots. Steerpike in his turn stepped over the threshold and his curiosity was more than assuaged.

If the name of the room was unusual there was no doubt about its being apt. It was certainly a room of roots. Not of a few simple, separate formations, but of a thousand branching, writhing, coiling, intertwining, diverging, converging, interlacing limbs whose origin even Steerpike’s quick eyes were unable for some time to discover.

He found eventually that the thickening stems converged at a tall, narrow aperture on the far side of the room, through the upper half of which the sky was pouring a grey, amorphous light. It seemed at first as though it would be impossible to stir at all in this convoluting meshwork, but Steerpike was amazed to see that the twins were moving about freely in the labyrinth. Years of experience had taught them the possible approaches to the window. They had already reached it and were looking out into the evening. Steerpike made an attempt at following them, but was soon inextricably lost in the writhing maze. Wherever he turned he was faced with a network of weird arms that rose and fell, dipped and clawed, motionless yet alive with serpentine rhythms.
