Jones was the head of scientific intelligence at the british intelligence service during the second world war, and this book is an account of his efforts in that time: anticipating the german efforts in scientific warfare based on intelligence findings, and developing countermeasures. The primary technical areas were bomber guiding systems, radar, and the V1 and V2 weapons.
Much of this is very interesting. His detailed accounts of the internal politics of british intelligence are a bit tiring at times, but maybe this only reflects how he himself has felt about these issues.
