"It was you," she said hoarsely, "who knocked at the door in the middle of the night."

"Where?" she demanded, her face contracting in a quick spasm.
"In the window yonder," and I heard her deep breath of relief. "I thought perhaps it was Miss Lawrence."
"It was I," she said, and I saw she was visibly forcing herself to go on. "I had been putting away some fruit in the cellar. Your knock at that hour startled me."
