Sex, Blackmail and Bribery: Soviet Spies' Trade is Treachery, MI5's 1960s-Era Booklet Warns

The British newspaper The Daily Mail reports that an MI5 booklet, originally created in the 1960s to warn British citizens traveling behind the Iron Curtain about the techniques Soviet spies use to ensnare them into espionage, is finally being released to the general public.

In Their Trade is Treachery, sex, blackmail and bribery were listed as some of the espionage techniques used by the Soviets. The 59-page booklet was produced by MI5, the British security service, at the time of the "Profumo Affair."

The scandal involved a call girl, Christine Keeler (seen in above photo), who was discovered to be the mistress of both a Soviet spy and John Profumo, the British Secretary of State for War.
