twelve o'clock
But I do n't know what I shall do without you . I think I shall run in to Mrs. Pettifer , and ask her to come and stay with me while you 're away . I 'm sure she will . ' At twelve o'clock , Janet , having seen her mother in the coach that was to carry her to Thurston , called , on her way back , at Mrs. Pettifer 's , but found , to her great disappointment , that her old friend was gone out for the day . So she wrote on a leaf of her pocket-book an urgent request that Mrs. Pettifer would come and stay with her while her mother was away ; and , desiring the servant-girl to give it to her mistress as soon as she came home , walked on to the Vicarage to sit with Mrs. Crewe , thinking to relieve in this way the feeling of desolateness and undefined fear that was taking possession of her on being left alone for the first time since that great crisis in her life . And Mrs. Crewe , too , was not at home ! Janet , with a sense of discouragement for which she rebuked herself as childish , walked sadly home again ; and when she entered the vacant dining-room , she could not help bursting into tears .
