“But certain religions,” I said, “involve the slaughter of human beings.”

“Yes, I know,” she said. “I’ve included them. That’s why those knives are hanging on the wall.”

“No, they’re cancelled out,” she said, “by the religions that forbid the taking of life.”

“But it seems to me,” I said, “that, at that rate, all your religions cancel each other out.”

“Yes,” she replied. “That’s what it often seems to me.”

“But then you haven’t a religion at all?”

“Well, I sometimes doubt it,” she said. “I often wonder if I did the right thing in embracing them?”

It was not to discuss her religion, however, that I had journeyed to Enfield, as I was now somewhat tartly obliged to remind her.

“And you seem to be forgetting,” I added, “that I’ve just been dismissed from the employment you were compelled to find me.”
