`` This is my card , '' said the lady -- `` Mrs. Rivers , Curzon Street , Mayfair -- and I shall expect you to-morrow afternoon -- that is to say , if the doctor approves of you . Here is one-and-sixpence for your cab fare . '' `` Thank you , ma'am . '' `` I shall expect you not later than four o'clock . I hope you wo n't disappoint me ; remember my child is waiting .
