midnight
`` It 's got to be done . Listen to me , Ganimard . According to what the maid says , Jenny Saphir led a very regular life . For a month past she was in the habit of frequently receiving visits , on her return from the music-hall , that is to say , at about half-past ten , from a man who would stay until midnight or so . ` He 's a society man , ' Jenny Saphir used to say , ` and he wants to marry me . ' This society man took every precaution to avoid being seen , such as turning up his coat-collar and lowering the brim of his hat when he passed the porter 's box . And Jenny Saphir always made a point of sending away her maid , even before he came .
