‘Only for a moment, only for a moment,’ they said. ‘Just passing – On our way home – Only for a moment – Tell him we won’t stay – No, of course not; we won’t stay. Of course not. Oh no – Yes, yes. Just a twinkling – only a twinkling.’

But for the fact that it would have been impossible for one voice to wedge so many words into so short a space of time and to speak so many of them simultaneously, it would have been difficult to believe that it was not the voice of a single individual, so continuous and uniform appeared the flat colour of the sound.

Prunesquallor cast up his hands to the ceiling and behind the convex lenses of his spectacles his eyes revolved in their orbits.

The voices that Steerpike now heard in the passage were unfamiliar to his quick ear. Since he had been with the Prunesquallors he had taken advantage of all his spare time and had, he thought, run to earth all the main figures of Gormenghast. There were few secrets hidden from him, for he had that scavenger like faculty of acquiring unashamedly and from an infinite variety of sources, snatches of knowledge which he kept neatly at the back of his brain and used to his own advantage as opportunity offered.

When the twins, Cora and Clarice, entered the room together, he wondered whether the red wine had gone to his head. He had neither seen them before nor anything like them. They were dressed in their inevitable purple.

Dr Prunesquallor bowed elegantly. ‘Your Ladyships,’ he said, ‘we are more than honoured. We are really very much more than honoured, ha ha ha!’ He whinnied his appreciation. ‘Come right along, my dear ladies, come right the way in, Irma, my dear, we have been doubly lucky in our privileges. Why “doubly” you say to yourself, why “doubly”? Because, O sister, they have both come, ha ha ha! Very much so, very much so.’

Prunesquallor, who knew from experience that only a fraction of what anyone said ever entered the brains of the twins, permitted himself a good deal of latitude in his conversation, mixing with a certain sycophancy remarks for his own amusement which could never have been made to persons more astute than the twins.

Irma had come forward, her iliac crest reflecting a streak of light.

‘Very charmed, your Ladyships; I said “very, very charmed”.’

She attempted to curtsey, but her dress was too tight.

‘You know my sister, of course, of course, of course. Will you have coffee? Of course you will, and a little wine? Naturally – or what would you prefer?’

But both the Doctor and his sister found that the Ladies Cora and Clarice had not been paying the slightest attention but had been staring at Steerpike more in the manner of a wall staring at a man than a man staring at a wall.
