I knew next to nothing about the activities of this group of people. The book is well written, full of anecdotes and descriptions of places and people and frightening when you think about what the intentions of the "villains" were.
I had seen George Cluny's film which was an introduction to these heroes these . However, the film only brushes the story of these men and women who saved our art history in all its forms during the first world war. The film just touches on a story which every art lover should read about in the book.
