Half an hour later Florence and Bertha were on their way to Hilchester. Both girls were feeling anxious.  Florence had that weight of care ever at her heart, and Bertha was wondering by what means she could smuggle the letter to Mrs. Aylmer out of her daughter's hands.  Think and think as she would, however, she could see no way of preventing that postoffice order being obtained, of its being slipped into the envelope, and put into the post.  She was noted for her ready wit, however, and ingenuity, and she could only now trust to what she termed a lucky chance.  One thing, however, was more important than ever; she must as quickly as possible get Florence into her power.
