Let’s Crack Zodiac – Episode 4 – National Cryptologic Museum

The National Cryptologic Museum has been closed due to the pandemic, so they’ve been doing a series of online educational events. They invited me to give a lecture about the Zodiac ciphers.  Check it out in my latest episode of Let’s Crack Zodiac:

Topics include Zodiac’s crimes, letters, postcards, ciphers, mysterious symbols, and copycat ciphers.
