My cousin—Louis Auchincloss?

After the invasion he was sent to the Pacific and while onboard a ship to Japan wrote another novel, only to throw it in the trash. He finally began his writing career with “The Indifferent Children,” a novel published by Prentice-Hall in 1947 after he had returned to Sullivan & Cromwell. It appeared under the pseudonym Andrew Lee, in deference to his mother, who thought the book “trivial and vulgar” and feared it would damage his career. —NYT
