Hubert Wolf, The Nuns of Sant’Ambrogio: The True Story of a Convent Scandal. Vintage, 2015. Translated from the German by Ruth Martin.
I first heard of this book via Lady Business, where it was spoken of in very complimentary terms. I can confirm that it is extremely solid history writing, clear and thorough and immensely readable: the kind of history where you keep reading in order to find out just what happened next.
Wolf deals with a particular convent scandal, one that took place in the convent of Sant’Ambrogio in Rome and was investigated as a result of a complaint made by the German Catholic Princess Katarina von Hohenzollern to the Holy Office for the Doctrine of the Faith (the office of the Inquisition). Katarina had entered the convent as a postulant and then a novice (after two marriages and a previous unsuccessful attempt to become a nun in a different convent) and came to believe that she was being poisoned by the sisters of Sant’Ambrogio, as a result of her opposition to certain practices she believed were entirely improper.
Wolf draws on several archival sources, including the Inquisition’s own files and the testimony of the witnesses and defendants in the case, to illuminate the life of the Hohenzollern princess, the convent, the other nuns, Church politics, and the case itself. False saints, poisonings, political manoeuvring in the Jesuit order, the curia, and the papacy, Solicitatio by priests in confession, sexual assault of novices, female sodomy: this is history mixed with true crime, and Wolf lays it all out in fascinating detail.
Including a good deal of detail on how the Inquisition actually investigated the charges laid before it, which is fascinating in its own right.
