Phyllis Dorothy James, better known to readers as P.D. James, died "peacefully at her home in Oxford" this morning, according to her agent. She was 94.
Her most recent book was 2011's Death Comes to Pemberley, a murder-mystery sequel to Jane Austen's Pride and Prejudice.
Her publisher, Faber and Faber, said in a statement:
It is difficult to express our profound sadness at losing PD James, one of the world's great writers and a Faber author since her first publication in 1962.
She was so very remarkable in every aspect of her life, an inspiration and great friend to us all. It is a privilege to publish her extraordinary books. Working with her was always the best of times, full of joy. We will miss her hugely.
