"Night before last I sat till eleven, studying. Against the rules, I know; but I forgot, and when I was through I opened my window to air the room. It was bright moonlight, so I took a stroll along the top of the piazza, and coming back with my eyes on the sky I naturally saw the roof of the main house from my wing. I couldn't have been asleep, could I? yet, I solemnly declare I saw a white figure with a veil over its head roaming to and fro as quietly as a shadow. I looked and looked, then I called softly, but it never answered, and suddenly it was gone."
"What did you do? quavered Cordy, in a smothered voice from under the pillow.
"Went straight in, took my lamp and marched up to the cupola. Not a sign of any one, all locked and the floor dusty, for we never go there now, you know. I didn't like it, but just said, 'Sally, go to bed; it's an optical illusion and serves you right for studying against the rule.' That was the first time."
"Mercy on us! Did you see it again?" cried Maud, getting hold of Julia's strong arm for protection.
"Yes, in the bowling-alley at midnight," whispered Sally.
"Do shut the door, Kit, and don't keep clutching at me in that scary way; it's very unpleasant," said Nelly, glancing nervously over her shoulder as the six pairs of wide-opened eyes were fixed on Sally.
"I got up to shut my window last night, and saw a light in the alley. A dim one, but bright enough to show me the same white thing going up and down, with the veil as before. I'll confess I was nervous then, for you know there is a story that in old times the man who lived here wouldn't let his daughter marry the lover she wanted, and she pined away and died, and said she'd haunt the cruel father, and she did. Old Mrs. Foster told me all about it when I first came, and Madame asked me not to repeat it, so I never did. I don't believe in ghosts, mind you, but what on earth is it, trailing about in that ridiculous way?"
Sally spoke nervously and looked excited, for in spite of courage and common sense she was worried to account for the apparition.
"How long did it stay?" asked Julia, with her arm round Maud, who was trembling and pale.
"A good fifteen minutes by my watch, then vanished, light and all, as suddenly as before. I didn't go to look after it that time, but if I see it again I'll hunt till I find out what it is. Who will go with me?"
