Martin Chuzzlewit (Cronos Classics)

Martin Chuzzlewit has been raised by his grandfather and namesake. Years before, Martin senior took the precaution of raising an orphaned girl, Mary Graham. She is to be his nursemaid, with the understanding that she will be well cared for only as long as Martin senior lives. She thus has strong motivation to promote his well-being, in contrast to his relatives, who only want to inherit his money.
However, his grandson Martin falls in love with Mary and wishes to marry her, ruining Martin senior's plans. When Martin refuses to give up the engagement, his grandfather disinherits him.
