"Tony Insall's account and analysis is well-written and well-researched and contains many new insights and new details ... The book is undoubtedly essential, even indispensable, reading for anyone who is interested in Anglo-Norwegian relations and how it most likely made a substantial contribution to the Second World War as a global maritime conflict." - Journal of Strategic Studies "Brings some clarity to a complex picture of codenamed operations and agents ...
