No, not yet, Most gracious prince! you must delay till night. Each avenue is watched, the guards are doubled You ne'er could reach the palace unperceived; You would endanger everything. (CARLOS: And yet----) I know one means alone that can avail us. 'Tis the queen's thought, and she suggests it to you; But it is bold, adventurous, and strange! (CARLOS: What is it?) A report has long prevailed That in the secret vaults, beneath the palace, At midnight, shrouded in a monk's attire, The emperor's departed spirit walks. The people still give credit to the tale, And the guards watch the post with inward terror. Now, if you but determine to assume This dress, you may pass freely through the guards, Until you reach the chamber of the queen, Which this small key will open. Your attire Will save you from attack. But on the spot, Prince! your decision must be made at once. The requisite apparel and the mask Are ready in your chamber. I must haste And take the queen your answer.
