In November 1966, Truman Capote threw a legendary Black and White Ball at New York's Plaza Hotel. Who was invited? 540 of Capote's "closest friends."

[How did "the 400" come to signify the wealthiest and most fashionable members of society in 1892? This was the number of people which Mrs. William Astor's ballroom could comfortably accommodate.]

[Capote was writing for The New Yorker -- by the age of 15.]
