Voir Stories from the Vaults, Season 2 - Episode 2

Join host Tom Cavanagh in a thrilling peek at some of the hidden codes, strange symbols, and bizarre mysteries hidden in the world's most renowned museum complex. We'll meet a sculptor who encrypted a message so puzzling into his sculpture for CIA Headquarters in Langley that even today, 20 years later, the Agency's top cryptographers haven't been able to crack the code. The Post Office has its share of secrets, too, and we go to the National Postal Museum to learn about the hush-hush shipment of the Hope Diamond, as well as a truly odd Cold War program for sending secret messages by guided missile.
