This unvarnished deep dive into the women of the secret services begins in the 17th century, when Oliver Cromwell coins the neologism "she-intelligencers". The veritable odyssey continues right up to the present, with Gina Haspel running the CIA up until 2021. Portraits and revelations punctuate this genuine, real-life thriller with a discovery on every page: the truth about Mata Hari and Milady de Winter; the female "unknown soldiers" of the Great War; the fairer sex frontlines of Stalin and Hitler; the heroines and traitresses of the Occupation; Churchill's lady saboteurs; Roosevelt's disinformation women; and the femme fatales in the Mossad, MI6, the SVR, the Guoanbu, and the CIA.
