In addition to the economic dynamics of domestic employment, the mistress-maid relationship as depicted in 19th century fiction brings in themes of loyalty, devotion, and female alliance, although the last is mostly a fictional invention. When servants feature in fiction (which is rare) these conditions create a homoerotic potential. Two women, separated by class but existing in close physical proximity, invite images of unrequited love and yearning, and sometimes their fulfillment. Conversely, the appearance of an employment relationship may serve as cover for a queer relationship.
