"I had sat for about twenty minutes turning the thing over in my mind and trying to find some possible explanation. The more I thought, the more extraordinary and inexplicable did it appear. I was still puzzling over it when I heard the door gently close again, and her footsteps coming up the stairs. "'Where in the world have you been, Effie?' I asked as she entered.

"'You awake, Jack!' she cried, with a nervous laugh. 'Why, I thought that nothing could awake you.' "'Where have you been?' I asked, more sternly. "'I don't wonder that you are surprised,' said she, and I could see that her fingers were trembling as she undid the fastenings of her mantle. Why, I never remember having done such a thing in my life before.
