Hodge stared at his friend as if wondering if Frank's mind was not affected.

"What do you mean?"

"Just what I have said to you. I saw an apparition that resembled Barney Mulloy. And I not only saw it, but I heard it. It came right along here, and turned in there, and then I heard it in the corridor. I threw open the corridor door before any one could have got out of there, and the corridor was empty!"

"You must have been dreaming!"

"Not a bit of it, Bart. I hadn't gone to bed. I haven't been even a bit sleepy. I was sitting at my window, and I saw it as plainly as I see you."

"You certainly must have been dreaming, Merry!" Bart insisted. "Have you looked all about?"

"Everywhere."

Bart walked over to the door which opened from the corridor on the lawn. It was not locked.

"It couldn't have been Barney, of course; but whoever it was went through here into the corridor."

"And how did he get out of the corridor?"
