In the mid-1800's, the wealthy Sloper family - widowed surgeon Dr. Austin Sloper, his adult daughter Catherine Sloper (Dr. Sloper's only surviving child), and Dr. Sloper's recently widowed sister Lavinia Penniman - live in an opulent house at 16 Washington Square, New York City. They have accrued their wealth largely through Dr. Sloper's hard work. The first man ever to show Catherine any attention is the handsome Morris Townsend, who she met at a family party.
