"No. He is away. His book frightens me."

"Frightens you," said Don, staring curiously. "In what way?"

"I don't know that I can explain. I feel afraid for him."

"For Paul?"

"Yes."

"Because he has seen the truth?"

Flamby hesitated. "It must be awful for a doctor who has specialised in some dreadful disease to find——"

"That he suffers from it? This is a common thing with specialists." Don spoke almost heedlessly, but had no sooner spoken than he became aware of the peculiar significance of his words. He sat staring silently at Flamby. Before he had time for further speech Regali attended in person to announce that places were vacant at one of the tables. This table Don and Flamby shared with a lady wearing her hair dressed in imitation of a yellow dahlia, and with a prominent colourist who was devoting his life to dissipating the popular delusion about trees being green. He was gradually educating the world to comprehend that trees were not green but blue. He had a very long nose and ate French mustard with his macaroni. The conversation became cubical and coloured.

"I maintain," said the colourist, who was fiercely cynical, as might have been anticipated of one who consumed such large quantities of mustard, "that humanity is akin to the worm. The myth of Psyche and the idea that we possess souls arose simply out of the contemplation of colour by some primitive sensitive. Very delicately coloured young girls were responsible for the legend, but humanity in the bulk is colourless and therefore soulless. Large public gatherings fill me with intense personal disgust. From Nelson's point of view, a popular demonstration in Trafalgar Square must unpleasantly resemble a box of bait."

"Clearly you have never loved," said Don. "One day some misguided woman may marry you. You will awaken to the discovery that she is different from common humanity."
