For hours she would sit in the window at night, looking out into the park, as you know, and daytimes, when you were away, many is the time I have found her on her bed, shaking with her misery and tears.

I asked those questions, too, when one night—a month ago—she came into my bedroom, walking like a ghost in her bare feet.

“Margaret,” she whispered, trembling, “I can’t wake Mr. Estabrook. I haven’t the courage to. I want you to come to the front windows.”

“Look! Now! Behind that post over the way!” she said, pinching my arm. “Do you see him?”

“See who?” I gasped. “What is it? I see nothing.”

“He stretched his hands out!” she cried. “He isn’t real! You see nothing?”
