“Yes,” she said quietly. “Yes, he has already written two, and a great number of papers which have been highly acclaimed. But this was to be of a much deeper nature than before, and possibly more controversial.” She looked at him closely to make sure he understood. “That is why he needed Unity’s skills in the translation of sources for the work.”

“Was she interested in the subject?” He must be patient with her. This meandering might be the only way she could bring herself to tell the one bitter truth which mattered.

Vita smiled. “Oh, not the theological side of it, Superintendent. Not in the slightest. Unity is… was… very modern in her beliefs. She did not believe in God at all. In fact, she was a great admirer of the work of Mr. Charles Darwin.” A look of deep distaste flickered across her eyes and mouth. “Are you familiar with it? Of course you are. At least you have to be aware of what he propounds on the origins of mankind. There was never a more dangerous and daring idea put forward by anyone since… I don’t know what!” She was concentrating fiercely, turning her body on the chaise longue until she faced him more fully, regardless of the discomfort it must have caused her. “If we are all descended from apes and the Bible is not true at all and there is no God, then why on earth should we go to church or keep any of the Commandments?”

“Because the Commandments are based upon virtue and the best social and moral order we know,” he replied. “Whether they originate with God or with the long-fought-for and refined ideas of men. Whether the Bible is right, or Mr. Darwin is right, I don’t know. There may even be some way in which they may both be. If not, I hope profoundly that it is the Bible. Mr. Darwin leaves us with little more than the belief in progress and human morality steadily ascending.”

“Don’t you believe it will?” she said seriously. “Unity believed it very strongly. She thought we were progressing all the time. Our ideas are getting nobler and freer with every generation. We are becoming more just, more tolerant and altogether more enlightened.”
