Katya,  a beautiful Russian book editor, attempts to send British publisher Barley Blair a manuscript written by a noted Soviet scientist and in doing so unwittingly draws them both into a world, of international espionage. The manuscript, containing information that could alter the balance of world power,  is intercepted by Western spy-masters who then send Blair to Russia to gain more information on the mysterious document.  But when Blair meets Katya, he is torn between his mission and the woman whose passion for her country - and for Blair - know no bounds. Also starring Roy Scheider and James Fox. And for more John  Le Carrè:  https://cosmiccauldronbooks.com.au/p/the-little-drummer-girl-john-le-carre/
