The Great War magazine, September 2018 – reviewed by Mark Marsay

A fascinating well told historical story providing an insight into not only the detailed social underworld of prostitution and social entertainment during the Great War, but also the significant roles played leading to a better understanding of the amusement and morality of the troops and the neutrality of the Swiss.

Essex Family Historian No.164

A native of Switzerland, Marie-Antoinette (aka Regina Diana circa 1910) was tried to death by the French for being a German spy. It's with this narrative that Newman switches tracks frequently in a chatty way to tell of what's known of her and about the history of female European and American spies. It's interesting to learn about spy ring correspondence with the use of invisible ink and hotel letter drops, Switzerland's neutrality leading to it being a hotbed for spy recruitment, and Regina Diana being tapped to engage in espionage in France, Spain, and Algiers before her death in January 1918 at the age of 32, but it's that switching of tracks which led to my attention waning.
