“Yes, the shadow was gone,” replied Betty, “but it was more than a shadow, Bob! A shadow can not turn off a light!

“I was frightened, Bob. I went all around downstairs, but I found nothing. Not even a window open.”

“You’d better forget it,” said Bob. “Your imagination is getting the best of you. How about that trip I suggested? Why not go?”

“I don’t want to leave New York,” declared Betty firmly.

“But this house is no place for you,” returned Bob. “Not while you’re in your present state of mind.”

Betty was inclined to agree. She remembered that she had been invited to visit a friend in the city — Alice Wheeler. Perhaps Bob was right when he said that she should go away a while. So she offered a compromise.

“Alice Wheeler wants me to visit her,” she said. “Suppose I go over there for a few nights?

“But I don’t like the idea of you staying here, Bob,” she went on. “Something is wrong in this house!”

“Don’t you worry about me,” declared Bob. “I’ll be all right. It’s you I’m worried about. I’d advise you to go today.
