I tiptoed a hundred feet along the wall and peered around a turret up to a room above, where Hobson's head could easily be seen in a patch of light. The ghost, at that moment, was walking just below, and the effect on the old man, appalling though it was, was ludicrous as well. He was leaning far out of the window, his mouth wide open; and the entire disk of his fat, hairless head was as pallid as the moon itself. The specter, who was now rounding the curve of the wall near the tower, swerved suddenly, and as suddenly seemed to totter headlong into the abyss below. As he dropped, a wild laugh broke through the frosty air. It wasn't from the ghost. It came from above—yes, it emanated from Thaddeus Hobson, who had, apparently, fallen back, leaving the window empty. Lights began breaking out all over the castle. In another moment I should be caught in my foolish disguise. With the courage of a coward, I turned and ran full tilt along the dizzy ledge and back to my window, where I lost no seconds scrambling up the rope that led to my room.

With all possible haste I threw aside my sheet and helmet and started downstairs. I had just wrestled with a ghost; I would now have it out with the old man. The castle seemed ablaze below. I saw the flash of a light skirt in the picture gallery, and Anita, pale as the vision I had so lately beheld, came running toward me.

“Father—saw it!” she panted. “He had some sort of sinking spell—he's better now—isn't it awful!” She clung to me, sobbing hysterically.

Before I realized what I had done, I was holding her close in my arms.

“Don't!” I cried. “It was a good ghost—he had a finer spirit than mine. He came to-night for you, dear, and for me. It was a foolish thing we planned.”

“Yes, but I wanted, I wanted to go!” she sobbed now crying frankly on my shoulder.

“You are going with me,” I said fiercely, raising her head. “But not over any ghost-ridden breakneck wall. We're going this time through the big front door of this old castle, American fashion, and there'll be an automobile waiting outside and a parson at the other end of the line.”

We found Thaddeus Hobson alone, in the vast hall looking blankly at the fire.

“Jeff,” he said solemnly, “you sure brought me luck to-night if you can call it such being scared into a human icicle. Br-r-r! Shall I ever get the cold out of my backbone? But somehow, somehow that foggy feller outside sort of changed my look on things. It made me feel kinder toward living folks. Ain't it strange!”

“Mr. Hobson,” I said, “I think the ghost has made us all see things differently. In a word, sir, I have a confession to make—if you don't mind.”
