"But it is your duty to account for it. You alone are responsible; and it is my duty to enquire where it has gone."

"Miss Roscoe! You surely don't think I've pocketed it?" broke out Gwen, the drift of the Principal's remarks suddenly dawning upon her.

"I say nothing except that it is a very strange circumstance that you cannot produce it. Was the satchel in your own possession the whole of the afternoon?"

"Yes—at least—yes, it was!" stammered Gwen, looking very red and confused. The remembrance had just struck her that she had allowed Lesbia to take some change from her bag, and at the same instant Lesbia's extraordinary behaviour of the evening before flashed across her mind. Could there possibly be any connection between the two incidents? The idea was so horrible that she blushed at entertaining it even for a moment.

Miss Roscoe glanced at her keenly.

"Do you assume the full responsibility for this?" she asked in a strained voice.

"Absolutely. Nobody except myself had anything to do with the gate money."

The Principal's face, which had been grave before, took a yet sterner expression.

"I am sorry, Gwen. Very sorry and most concerned. I thought I could have trusted you entirely. It pains me beyond measure to find you have betrayed my confidence."

"But I didn't take that nine and six! I didn't, indeed! I don't know where it has gone; but I haven't got it! How can you accuse me of such a dreadful thing?" blurted out Gwen indignantly.
