Episode 373: Spycrafte

In Early Modern Europe, spying was not really a profession but it certainly was a verb. At times it would seem, from the dark suspicious years at the end of Henry VII’s life, to Cromwell’s protectorate and the restoration of the Stuart monarchy, that it was a game that everyone was playing. And in an era in which anyone with a modicum of political power was, figuratively speaking, always looking over their shoulders for rivals, they were literally driven to read each other’s mail. But reading the mail has its difficulties. How to unseal and reseal a letter so that no one knows that you have opened it? And when you discover the letter is encoded, how to decipher it? And so the game of spy vs. spy went on in the seventeenth century, pretty much as it does now, save for a few technological developments.  With me to discuss the world of early modern spycraft, mostly in Britain, are Nadine Akkerman and Pete Langman, coauthors of Spycraft: Tricks and Tools of the Dangerous Trade from Elizabeth I to the Restoration. Nadine Akkerman is professor of early modern literature and culture at Leiden University,  and author of the acclaimed Invisible Agents. Pete Langman is an Oxford English Dictionary bibliographer, author of Killing Beauties, and a cricketer.
