`` Willy ! '' she gasped . `` You are doing something dangerous ! '' `` What I really expect , '' he said , smiling down at her , `` is to be back , feeling more or less of a fool , by eleven o'clock .

She sat for some time after he had gone , fingering the blank white envelope and wondering , a little frightened but very proud of his trust .
