“Plock’s deep research and engaging writing style mean that this book could be enjoyed by anyone with an interest in the Second World War, inside or outside the academy. For media historians, it provides an excellent template … towards those focused on programme-makers and audiences. This is an important book for anybody interested in the history of the BBC and its External Services, and should be the first port of call for anyone studying the German Service.” (Christopher Day, Historical Journal of Film, Radio and Television, Vol. 42 (2), 2022)
