`` Why , you actually sound as if you intended to break the rules , '' said Billie , drolly adding , with a prim little pucker of her mouth : `` Laura , I 'm surprised at you . '' `` Listen to the good little girl talking , '' gibed Laura . `` I never knew you to get into any mischief , Billie , -- oh , no ! '' `` Well , I wo n't quarrel with you about it , '' said Billie , calmly adding with a little chuckle : `` If we try to have any midnight feast at Three Towers with sweet Amanda wandering round loose we will have to appoint a guard to stand outside the door and warn us . '' `` I suppose that will be my job , '' said Violet plaintively . `` It will be lots of fun standing out in a drafty hall looking for Amanda while you girls are having a feast . '' `` No , we 'll fix it so it will be perfectly fair , '' said Billie soothingly .
