Charles Dickens said this quote
“ They meet again at dinner--again, next day-- again, for many days in succession. Lady Dedlock is always the same exhausted deity, surrounded by worshippers, and terribly liable to be bored to death, even while presiding at her own shrine. Mr. Tulkinghorn is always the same speechless repository of noble confidences, so oddly but of place and yet so perfectly at home. They appear to take as little note of one another as any two people enclosed within the same walls could. But whether each evermore watches and suspects the other, evermore mistrustful of some great reservation; whether each is evermore prepared at all points for the other, and never to be taken unawares; what each would give to know how much the other knows--all this is hidden, for the time, in their own hearts. ”
