This book uses the theft of the Mona Lisa in 1911 as an opportunity to survey the crime scene of Paris 1896-1914. They look at the theft and then police techniques, notorious criminals, and famous cases. One error in the last chapter: they claim Dada started in Geneva rather than Zurich (I studied Dada literature and lived in Zurich for a year).I read this as part of my background research for Salazar. It was a lively and fun read. I picked up a few interesting details which may crop up in the Salazar books. This was really deep research as it ends in 1914 where Salazar begins in 1930.This book is a good read – you can sit and read it like a novel.
