four o'clock
Can you have it ready the night before ? '' `` It would really be safer to take it in the afternoon , '' Cecilia said after a moment 's thought . `` Mrs. Rainham 's absence will make that quite easy , for I know I can depend upon Eliza and Cook . I can get my trunks ready , leave them in my room , and tell Eliza you will be there to call for them , say , at four o'clock . Then I take the three children out for a walk , and when we return everything is gone . Will that do ? '' `` Perfectly , '' said Bob , laughing .
