"Come into the shop," he said, and led the way into its recesses.
"This is not an ordinary shop," he explained, as Peter began to read some titles. "I am a specialist."
"What is your subject?" Peter formally inquired.
"Revolution. Every book in this establishment is a revolutionary book. All my books are written by authors who know that the world is wrong, and that they can put it right."
"Who know that the world is wrong?" Peter echoed.
"That's the idea."
"I know that the world is wrong," said Peter wearily. "I want to know the reason."
"It's a question of temperament," said the bookman. "Some like to think it is a matter of diet or hygiene. Here is the physiological, medical, and health section. Some think it is a question of beauty and ugliness. The art section is to your right. Or perhaps you are an economist?"
Peter, who had not yet compassed irony, looked curiously at his new friend.
"Seriously?" he said at last, and paused irresolutely.
