In 1929, Yorkshire lass Rosina Harrison became personal maid to Lady Astor: the first female Member of Parliament to take her seat and wife of one of England's wealthiest lords. Lady Astor was brilliant yet tempestuous, but outspoken Rose gave as good as she got. For 35 years a battle of wills and wits raged between the two women, until an unlikely friendship began to emerge. The Lady's Maid is a captivating insight into the great wealth 'upstairs' and the endless work 'downstairs'.
