The Woman Who Smashed Codes

I was left at times wanting more detail on the process. I got the sense sometimes that the author didn't understand the technical details of what Elizebeth and her husband were doing but thought that the story was interesting. The story is well told, but I left wanting more, especially regarding the technical details of the process and her breakthroughs. At the same time the book felt long. Worth reading, but I wouldn't read again and I probably should have skimmed more.
