Recently read: The Last Judgement, Giotto’s Hand, and Death and Restoration, by Iain Pears
Books four through six of Pears’ Art History Mysteries series. All reasonably good (and all better than The Bernini Bust), but the best is Death and Restoration,1 which follows the formula of the most successful books in the series: it’s set in Italy, it focuses primarily on a single painting, and it has a nice twist ending.
