midnight
Go now -- leave me ; remove all traces of your crime . I shall take care to have a quantity of plate removed from the house to-night , and destroyed , and when his lordship returns to-morrow , he will imagine that Lagrange , despite his supposed faithfulness and integrity , has absconded and stolen the plate , -- that will account to him for the valet 's sudden disappearance . Leave me . ' '' ` Remember , at midnight , your ladyship , ' said I , and left her ; but when I had closed the door of the apartment , I imagined that I heard her give utterance to a scornful laugh . However , I attributed it to her gratification at the death of Lagrange , and descending to the wine cellar , I busied myself in washing away the stains of blood from the floor . How impatiently I longed for the arrival of midnight ! the hour that was to bring with it the reward of my crime !
