midnight
Emily now listened , with very anxious attention , to the narrative of Du Pont , who proceeded : `` In granting this indulgence , he knew , that he had nothing to apprehend from a chance of my escaping from a castle , which was vigilantly guarded , and the nearest terrace of which rose over a perpendicular rock ; he showed me also , '' continued Du Pont , `` a door concealed in the cedar wainscot of the apartment where I was confined , which he instructed me how to open ; and which , leading into a passage , formed within the thickness of the wall , that extended far along the castle , finally opened in an obscure corner of the eastern rampart . I have since been informed , that there are many passages of the same kind concealed within the prodigious walls of that edifice , and which were , undoubtedly , contrived for the purpose of facilitating escapes in time of war . Through this avenue , at the dead of night , I often stole to the terrace , where I walked with the utmost caution , lest my steps should betray me to the sentinels on duty in distant parts ; for this end of it , being guarded by high buildings , was not watched by soldiers . In one of these midnight wanderings , I saw light in a casement that overlooked the rampart , and which , I observed , was immediately over my prison-chamber . It occurred to me , that you might be in that apartment , and , with the hope of seeing you , I placed myself opposite to the window . '' Emily , remembering the figure that had formerly appeared on the terrace , and which had occasioned her so much anxiety , exclaimed , `` It was you then , Monsieur Du Pont , who occasioned me much foolish terror ; my spirits were , at that time , so much weakened by long suffering , that they took alarm at every hint . '' Du Pont , after lamenting , that he had occasioned her any apprehension , added , `` As I rested on the wall , opposite to your casement , the consideration of your melancholy situation and of my own called from me involuntary sounds of lamentation , which drew you , I fancy , to the casement ; I saw there a person , whom I believed to be you .
