I faltered during the preface to this account of the rise of the female (British) diplomat. Helen McCarthy, a historian at London University’s Queen Mary college, describes herself as being drawn to this subject by meeting diplomats (male) who were ‘bloody brilliant’. I feared a breathlessly deferential narrative. Then, as I started reading the text itself, I found myself getting scratchy at minor errors — titles and the like — and had I not promised to write a review, I should have switched to a thriller on my Kindle.
