Plot summary
Part one
Sue Trinder, an orphan raised in "a Fagin-like den of thieves" by her adoptive mother, Mrs Sucksby, is sent to help Richard "Gentleman" Rivers seduce a wealthy heiress. Posing as a maid, Sue is to gain the trust of the lady, Maud Lilly, and eventually persuade her to elope with Gentleman. Once they are married, Gentleman plans to commit Maud to a madhouse and claim her fortune for himself.
Sue travels to Briar, Maud's secluded home in the country, where she lives a sheltered life under the care of her uncle, Christopher Lilly. Like Sue, Maud was orphaned at birth; her mother died in a mental asylum, and she has never known her father. Her uncle uses her as a secretary to assist him as he supposedly compiles a dictionary, and keeps her to the house, working with him in the silence of his library.
