Their destination was Great Neck, Long Island, a playground for the newly rich where Fitzgerald would find himself surrounded by the wealth, parties, affairs and excesses that would eventually find their way into arguably his greatest novel — "The Great Gatsby." It's pretty easy to see how the Fitzgeralds' life on Long Island helped give rise to the story of Jay Gatsby, a mysterious North Dakota native who reinvents himself and becomes entangled with wealthy and careless people, illicit love, social climbing, mistaken assumptions — and murder. Literary scholar Sarah Churchwell argues in her 2013 book, "Careless People: Murder, Mayhem, and the Invention of The Great Gatsby," that the nearly forgotten crime was among the real-life events Fitzgerald absorbed while giving life to Gatsby.
