Synopsis.
After one book that ended up in the remainder bins, novelist Byron Tiller's inability to pay the bills strains relations with his wife. Desperate for any kind of income, he meets Luther Fox, an Englishman who runs an exclusive escort service called Elysian Fields, and is offered a job.
Hiding his new employment from his wife, Byron finds that one of his clients, Andrea, is married to a much older, ill Pulitzer Prize-winning author whom Tiller greatly admires.
