Lady Duff Gordon is the toast of Victorian London. But when her debilitating tuberculosis means exile, she and her devoted lady's maid, Sally, set sail for Egypt. It is Sally who describes, with a mixture of wonder and trepidation, the odd ménage marshalled by the resourceful Omar, which travels down the Nile to a new life in Luxor. As Lady Duff Gordon undoes her stays and takes to native dress, throwing herself into weekly salons; language lessons; excursions to the tombs; Sally too adapts to a new world, affording her heady and heartfelt freedoms never known before. But freedom is a luxury that a maid can ill-afford, and when Sally grasps more than her status entitles her to, she is brutally reminded that she is _mistress of nothing_.
