Diana Trilling, née Diana Rubin, was an American literary critic and author, a member of the circle of writers, thinkers and polemicists of the 1930's, 40's and 50's known as the "New York intellectuals". She was married to foremost US literary and cultural critic Lionel Trilling. They had one child, James.
Trilling was a well-known book reviewer for The Nation magazine. Her works include We Must March My Darlings (1977), an essay collection; Mrs. Harris (1981), a study of and meditation on the trial of Jean Harris; and The Beginning of the Journey (1993), a memoir of her life and marriage to Lionel.
I read this book back in the 80s. Having known Jean Harris and having followed her trial closely, it was impossible not to be completely consumed with this book.
