eleven o'clock
When I had dispelled him , I sat in the chair myself all day . I had my meals brought to me . And thus I escaped the sight of him for many hours , for he appears only in the chair . I was weary , but I sat late , until eleven o'clock . Yet , when I stood up to go to bed , I looked around , and there he was . He had slipped into the chair on the instant . Being only fabric of fancy , all day he had resided in my brain .
