“Quite so. But—”

“There can be no going back, sir,” continued Mr. Sagittarius. “Can there, Madame?”

“No human creature can go back,” said Madame Sagittarius. “Such is the natural law as exemplified by the great Charles Darwin in his Vegetable Mould and Silkworms. No human creature can go back. Least of all this gentleman. He must go forward and we with him.”

The Prophet began to feel uncomfortable.

“But—” he said.

“There is no such word as ‘but’ in my dictionary,” retorted the lady.
