A young woman, Cytherea Graye, is forced by poverty to accept a post as lady's maid to the eccentric Miss Aldclyffe, the woman whom her father had loved but had been unable to marry. Cytherea loves a young architect, Edward Springrove, but Miss Adclyffe's machinations, the discovery that Edward is already engaged to a woman whom he does not love, and the urgent need to support a sick brother drive Cytherea to accept the hand of Aeneas Manston, Miss Adclyffe's illegitimate son.
