More "one writ [sic] wonders" from TTel:

Margaret Mitchell - Gone With The Wind

Published in 1936, the sweeping tale of Scarlett O'Hara and the dashing Rhett Butler was an instant success. Mitchell, a writer for her local Atlanta newspaper, won the Pulitzer Prize and saw her debut novel turned into a Hollywood epic.

Mitchell hated fame and declared that she would not write another word as long as she lived. She died in a road accident in 1949. In 1995, an unpublished manuscript she had written as a teenager was discovered. It was published the following year as Lost Laysen, a romantic novella set in the South Pacific.

 
JD Salinger - The Catcher in the Rye

Although he wrote short stories and the novella Franny and Zooey, The Catcher in the Rye was Salinger's only novel. The author was believed to have retreated from society to spend his last half century as a hermit, until letters published in January this year revealed that he had been travelling the world, visiting West End shows and popping into Burger King, all the while happily chatting to strangers who had no idea who he was.

 
Emily Bronte - Wuthering Heights
Bronte published her one and only novel in 1847 under the pseudonym Ellis Bell. She died the following year of tuberculosis. In 1850, a new edition of Wuthering Heights was published with a preface written by her sister, Charlotte.
 
Anna Sewell - Black Beauty
Sewell wrote the children's classic in the last years of her life while confined to bed by ill health. It took her seven years and was published in November 1877. She lived just long enough to witness its early success.
 
Marcel Proust - A la recherche du temps perdu
Its 3,200 pages are split over seven volumes, but In Search of Lost Time counts as one novel. Proust started writing it in 1909, and was still working on it when he died in 1922
