midnight
Two , indeed , are sworn to us ; but the third can not be come at . He must be cut down afterwards ; and , indeed , when so many men must fall , what matters a eunuch more or less ? Thus it shall be , then . To-morrow night , at three hours before midnight thou dost cast the final augury of the issue of the war . And then thou wilt , as is agreed , descend alone with me , having the signet , to the outer chamber of the Queen 's apartment . For the vessel bearing orders to the Legions sails from Alexandria at the following dawn ; and alone with Cleopatra , since she wills that the thing be kept secret as the sea , thou wilt read the message of the stars . And as she pores over the papyrus , then must thou stab her in the back , so that she dies ; and see thou that thy will and arm fail thee not !
