three o'clock
`` My dear , '' said Mrs Ramsden , solemnly , `` this is indeed great news . I do n't wonder that you feel unnerved ! '' `` I do , indeed . The three o'clock post came in , and I was quite surprised when Mary came in with the salver . I was not expecting any letters . I have so few correspondents , and I am mostly in their debt , I am afraid . Still , of course , there are always the circulars .
