The Knox Brothers is a charming biography of Ronald Knox and his three remarkable brothers, written by his niece, Penelope Fitzgerald. It's a fascinating, humorous and insightful look at their characters, family life and the age into which they were born and lived.
Fitzgerald was also a rather remarkable author; she wrote short stories, novels, articles and essays, all after the age of 58. Julian Barnes wrote this short biography of Fitzgerald, whom he considered to be the "best English novelist of her time."
