During the World War II, several spies were double-crossers, for instance, a German military official seeming to be working for Britain or America, giving them very useful secret information about Germany’s military and other secrets, but at the same time, passing on secret information about Britain or America to Germany, getting benefits or money from both sides! Such people are also called ‘double agents’. This same tradition/practice continued during ‘cold war’ era, too!!
