I just re-read a book, that was on my kindle. I don't remember reading the first time at all! It was 5 years ago, which I only know because I wrote a review of it on Goodreads (below)! I'm laughing at myself here, because the big reveal at the end--which language was it on the tablets?--came as a complete and satisfying surprise the second time around, too. Hoo boy!
The Riddle of the Labyrinth: The Quest to Crack an Ancient Code, by Maraglit Fox
The story of American linguist Alice Kober's work to crack the code found on ancient Cretan tablets. As it was an unknown script in an unknown language, it was the hardest type to even attempt. Kober's efforts became the stepping stones used by Michael Ventris to solve the puzzle later. She has been largely left out of the narrative, thus this book.
I enjoyed learning about cryptography, and about the Linear B script in particular. The lives of the principal characters were also very interesting.
Just the kind of narrative nonfiction I like.
