Noel Malcolm, Agents of Empire: Knights, Corsairs, Jesuits and Spies in the Sixteenth-Century Mediterranean World. Oxford University Press, Oxford, 2016.
Malcolm, a historian who specialises in the history of the Balkans, has reconstructed the achievements (in the service of at least five crowns, counting the Papacy and Venice) of three generations of an Albanian family in the 1500s. From Venice to the borders of Poland, and the Vatican to Istanbul, the Brutis and their relatives the Brunis were at the heart of political, social, and military events across the Mediterranean.
It’s a really good book. I recommend it.
