'I mean, if you did not put them there yourself some one must have meddled with them, and it looks to me as if that some one had taken them away to look at, and then hurriedly put them back as near the door as she could get,' explained Miss Briggs.

'Then how do you account for them being removed?' demanded Miss Briggs.

'I can't account for it; but I would rather think that I put them there myself in an absent-minded moment than that they had been tampered with.'

'But you are never absent-minded, and you do not forget things,' objected Miss Briggs.

Vava took no heed of where she was when she spoke, and never noticed that she was passing Miss Upjohn's room, until Doreen said, 'Hush!'
