• A change was coming over Helen Perowne, forced by the terrible position in which she was placed, and roused now in spirit, she thought more and more deeply of all this, till it seemed to her that the Malay girl had struck the keynote of her future action, and that after feeling her way cautiously she had but to appeal to this attendant for her aid, and she would win her goodwill in an attempt to escape.
