four o'clock
That afternoon Sophia , too busy with her own affairs to notice anything abnormal in the relations between her mother and Constance , and quite ignorant that there had been an unsuccessful plot against her , went forth to call upon Miss Chetwynd , with whom she had remained very friendly : she considered that she and Miss Chetwynd formed an aristocracy of intellect , and the family indeed tacitly admitted this . She practised no secrecy in her departure from the shop ; she merely dressed , in her second-best hoop , and went , having been ready at any moment to tell her mother , if her mother caught her and inquired , that she was going to see Miss Chetwynd . And she did go to see Miss Chetwynd , arriving at the house-school , which lay amid trees on the road to Turnhill , just beyond the turnpike , at precisely a quarter-past four . As Miss Chetwynd 's pupils left at four o'clock , and as Miss Chetwynd invariably took a walk immediately afterwards , Sophia was able to contain her surprise upon being informed that Miss Chetwynd was not in . She had not intended that Miss Chetwynd should be in . She turned off to the right , up the side road which , starting from the turnpike , led in the direction of Moorthorne and Red Cow , two mining villages . Her heart beat with fear as she began to follow that road , for she was upon a terrific adventure .
