“I did,” said Caroline complacently.

I got up and began to walk about. “You realize what you’re doing, I hope,” I jerked out. “You’re putting a halter round Ralph Paton’s neck as surely as you’re sitting in that chair.”

“Not at all,” said Caroline, quite unruffled. “I was surprised you hadn’t told him.”

“I took very good care not to,” I said. “I’m fond of that boy.”
