midnight
Seizing my cloak , -- or rather yours , which you must of course lend me for the occasion -- I shall vanish through the window , never to return . For , of course , I shall take my leave this evening . But half-way back to Mantua , telling the coachman that I have forgotten some important papers , I shall return here on foot . Entering the garden by the side door -LRB- you must give me the master-key -RRB- , I shall creep to Marcolina 's window , which must be opened for me at midnight . I shall have taken off my clothes in the carriage , even to my shoes and stockings , and shall wear only your cloak , so that when I take to flight nothing will be left to betray either you or me . The cloak and the two thousand ducats will be at your disposal at five o'clock to-morrow morning in the inn at Mantua , so that you may deliver over the money to the Marchese even before the appointed hour . I pledge my solemn oath to fulfil my side of the bargain .
