The World's Second Oldest Profession - A World History of Espionage part one

I've enjoyed learning about espionage from the first time I watched a James Bond movie or learned about spies in world war II.  This audio series, The Modern Scholar: The Second Oldest Profession, Part 1: A World History of Espionage, provides information on the earliest forms of espionage up to the first part of the 20th Century.

The section on American Civil War espionage was an eye opener for me.  I was unaware of the Confederacy setting up a branch in Canada.  I was also unaware of the Australian and English Confederate war ships that were made for the Civil War. The slaves in the Civil War were also very valuable as they were invisible but heard everything.

Spying during Elizabethan England was series business.  Mary Queen of Scots plotted on several occasions with Catholic led foreign governments to have the protestant Queen Elizabeth removed from the throne. Extensive detective work and elaborate spying provided clear evidence of the final conspiracy to get rid of Elizabeth and finally convinced the Queen to have Mary executed.
