The story is true. The metaphors are probably Russian, but the prose is that of Norman Mailer (January 31, 1923 to November 10, 2007). Marina would marry an American named Lee Harvey Oswald. The details are in Mailer's book Oswald's Tale: An American Mystery (2007).
Mailer since his first book, The Naked and the Dead, (1948) was America's intellectual, ostentatiously trying to understand the American soul. It may be because of his ambitious reach that what some remember best are his spectacular failures of insight, like his part in obtaining freedom for a murderer, Jack Abbott, who quickly murdered again. Mailer had been impressed with the fellow's literary talent. But once, his Armies of the Night,(1968) were ours too, and we were happy he was on our side.
