The Age of Innocence
by Edith Wharton (1920)

A classic love triangle set against the backdrop of 1870s upper-class New York society. A portion of the novel takes place in Newport, Middletown, and Portsmouth, with specific references to the Newport Archery Club, Mill Street, Bellevue Avenue, Eastman's (Easton's) Beach, and Paradise Rocks (part of today's Norman Bird Sanctuary). A 1993 film version of the novel reportedly used Portsmouth as a shooting location.
