Are we secret agents? If we told you, we'd have to kill you. But this episode is all about them, so get ready! First, Anna gives a rundown of the type of espionage a government may take part in, and Benton tells the mysterious tale of Georgi Markov's assassination in London in 1978. Then, Anna relays the career of disgraced FBI agent Robert Hanssen, who worked as a double agent for the Soviet Union and Russia. Finally the two watch a classic episode of American Justice, profiling the thallium poisoning of Peggy Carr.
