Muriel Spark has died: Still in her prime. Her last novel, The Finishing School, published in 2004, became a best-seller. I reviewed it. It was delightful, characterized by "economy of means, precision of language and formal perfection." She lived in Tuscany too. God bless her.
There is more: Ian Rankin comments here. And Alan Taylor, literary editor of the Glasgow Herald, here. And Kelly Jane Torrance posts Spark of Genius.
