"I suppose the book must have been brought to school by somebody," said Kitty Harrison.

"It was not brought by me," said Patty. "I've no means of proving anything, but I've always been called truthful at home, and I think my word ought to hold good at The Priory too."

"Then whom does it belong to?" persisted Kitty. "Do you know anything at all about it?"

"Nothing," answered Patty; but the horrible suspicion lurking in the corner of her mind made her voice falter just a little, and some of the girls drew their own conclusions.

"Look here," said Enid, "I'd as soon believe Miss Harper smuggled that 'crib' into school herself as think Patty did! She's absolutely incapable of such a thing, and you all know it as well as I do. Why, it's Patty who's always tried to make us be fair over our work! She simply couldn't cheat. Hands up, all those who don't believe this hateful story!"

Jean, Winnie, and Avis held up their hands at once, and so, to the astonishment of most of her companions, did Muriel. Cissie Gardiner and Maggie Woodhall followed suit, but the others looked doubtful.

"I suppose we must accept Patty's word," said Beatrice, rather stiffly. "Still, it's a funny thing, and I wish it hadn't happened."

"Very funny, certainly, for the one who started the pledge," said Vera Clifford, under her breath.

"We shall find it out some day," said Enid. "I'm determined Patty's name shall be cleared. How any of you can be so idiotic as to connect her with it, I can't imagine. Never mind, Patty dear! We know you better than to believe such rubbish. Don't trouble your head about it, for it simply isn't worth worrying over. Everyone with a spark of sense will agree with me, and I'm sure Miss Harper will think the same."
