` Ca n't you stay all day to rest ? ' But Mrs. Fairchild shook her head , smiling . ` I must go home , ' she said . ` At the latest I must go home by ten o'clock . It will be all right till then . I can trust Celestina to see to her father 's breakfast and everything , and there 's not much doing in the shop before then . Celestina will have let Miss Neale know not to come . '
