Ok book

I really enjoyed this book. It kept me wanting to know what would happen next. I thought it also taught me a lot about history which was really interesting. A lot better then a text book for sure.

I LOVED this book. It teaches you about ciphers. I recommend it to detective fans.

I loved the book. I just did not like the main focus and how it was used.

omg this was a really good book. i loved it so much
