The "Secret War" lifts the veil of secrecy on the crucial role science and intelligence played behind the lines in winning World War 2. Presented by William Woollard and largely based on the book "Most Secret War" by R V Jones. Superbly presented by William Woollard, this fascinating documentary series is unusual and particularly good because of many interviews with the people involved with the development and countering of these secret weapons, including R V Jones.
