Dr. Edmondo Ricci, Senior Curator of the Uffizi Gallery, is found face-down on the floor of the Vasari Corridor — the elevated passage that connects the Uffizi to the Palazzo Pitti, running above the Ponte Vecchio and the commerce below it. He is positioned beneath the Gallery's self-portrait collection. Five centuries of artists looking at themselves, looking down at a man who spent twenty-two years studying genius and could not turn the same attention on himself. A word on vellum beside his right hand. Invidia. Envy. Commissioner Sonya Logan has been reading this curriculum for three cities. She arrives in Florence knowing more than she arrived in Venice knowing, which is the correct progression. She has a list of three names. She sent them to the Florence liaison before the body was found. She was right about one of them. Dr. John Lucas has been watching the investigation read his argument since Rome. He is the most careful reader in the room. He has been building toward Edinburgh since before the curriculum began. ENVY is the third novel in the Between Heaven and Hell series — eight books, seven deadly sins, seven European cities, and one diagnostician who only ever tells the truth. Where faith ends and desire begins, evil waits.
