How to be a Spy – Introduction by Denis Rigden

In the early years of World War II, Special Operations Executive (SOE) set up top secret training schools to instruct prospective agents in the art of being a spy. By the end of 1941, an international network of schools was in operation in secluded locations ranging from the Scottish Highlands to Singapore and Canada. How to Be a Spy reproduces the extensive training manuals used to prepare agents for their highly dangerous missions behind enemy lines. The courses cover a variety of clandestine skills including disguise, surveillance, burglary, interrogation, close combat, and assassination - everything needed to wreak havoc in occupied Europe.
