Spies and Secret Service The story of espionage, its main systems and chief exponents

"Spies and Secret Service" by Hamil Grant is a thorough exploration of the world of espionage, from its ancient origins to modern practice. The book examines the tricky moral questions around spying and how it has been defended as necessary for a country's safety and goals. Grant shows the spy as someone critical in war and politics, following the profession from early times through examples in the Bible and ancient wars; the tone is set for going deeper into looking at espionage as a job, underlining its effects on the mind and on society, and getting the reader ready to learn about specific spies and their daring missions later on.
