Rendezvous Info



From the piazzas of ancient Rome to the spy capitals of the Cold War, Kristie Macrakis reveals the global history of hidden communications. In her new book, Mackrakis, a professor of history, technology, and society at the Georgia Institute of Technology, has unearthed the drama and importance of secret messaging from Ovid’s advice to use milk for illicit love notes, to John Gerard’s dramatic escape from the tower of London aided by orange juice ink messages, to Al Qaeda’s hidden instructions in pornographic movies. Prisoners, Lovers, and Spies: The Story of Invisible Ink from Herodotus to al Qaeda is a page turning history of intrigue and espionage, love and war, magic and secrecy for anyone with an interest in learning more about the evolution and impact of the art of concealing messages.
