Could a novel ever feature a serious, underpaid middle-aged conservator?

Having just finished reading “The Hound in the Left-hand Corner”, by Giles Waterfield (Washington Square Press, 2002), a satire about an important day in the life of a British museum, I’m coming to the conclusion that museum novels are essentially the same book. They have odious museum directors, members of Boards of Trustees, and heads of security, as well as scheming curatorial and conservation staffs– none of whom resemble any museum employees I know. Could there ever be a museum novel featuring a conservator who is a serious, underpaid (for her level of knowledge and skills) middle-aged woman rather than an eccentric dandy or very young and glamorous girl?
