midnight
`` Perhaps I can tell you why you were here , '' Driggs went on , never losing his affable smile . `` You do n't like Dick Prescott , and you do n't like his boy friends . Prescott has been too many for you on more than one occasion . But that is no reason why you should enter my yard after midnight . That is no reason why you should want to do harm to a war canoe or to any other property that happens to be in my yard . I really do n't know whether you 're to be blamed for being a glib liar , Ripley . You 've never given yourself much practice at telling the truth , you know .
