The most recommended cryptanalysis books

A groundbreaking work of research that is at the same time a page-turning read that sheds new light on the epic battles of the conflict. Prados interweaves the intelligence successes and failures of the U.S. and Japanese combatants in a way that has not previously been attempted. The resulting work adds hugely to our understanding of the war in the Pacific.

It is hard to underestimate the significance of code breaking during World War II. Without the work of dedicated mathematicians, linguists, and others the great conflicts such as the Battle of Midway and the German U-boat "wolfpacks" that sank over 13 million tons of Allied supplies could have easily been up for grabs. But due to the codebreakers the balance shifted to the Allies. And what is even equally impressive is that the Axis powers never knew that their encoded messages were being read. Stephen Budiansky traces how the codebreakers pulled off this feat while at the same time often battling within their own ranks about who should decode the message, how the messages should be used, and who should get the credit.

This book has so many of my favorite elements: believable friendships among three very different women, Bletchley Park during World War II, with spies, and characters I adored: the debutante, the working-class girl, and the girl we’d now say is “on the spectrum.” I loved this book so much that I read everything Kate Quinn wrote, but this one’s still the best.

When Beth is threatened with a lobotomy, the suspense was terrifying. I kept thinking of my aunt whose existence was a family secret for years. I laughed and cried over this book and the women who helped win the War but had to keep their work a secret, even if it cost them everything and everyone they loved.

I’m fascinated by the way the code breakers at Bletchley helped to shorten the war. In Pam, McGurl has created a strong woman, who makes key choices, sometimes at the expense of her own happiness, to support the war effort. But what I really enjoyed was the time slip nature of the novel, where Pam is contrasted to her granddaughter Julia, a modern woman, who, when let down by the men around her, becomes empowered by her own freedom. It’s interesting to see how women’s roles have changed between the 1940s and today. 

I first heard of Pompouras from her role on a reality TV show Spy Games, but Becoming Bulletproof hooked me with her tale of her time as a Secret Service agent. It’s not a thriller, but don’t tell that to my heart rate as she described her experience of being in New York on 9/11.

I love the way she speaks about the challenges faced as a woman in her field and how she didn’t let the naysayers hold her back. I’ve referred to her book time and time again in my own work both for inspiration, and it’s a great handbook on the tips and tricks of how to read and influence people.  

David was a pioneer. Before Codebreakers there was next to nothing in print about codebreaking. Focused on World War II, he introduced a generation of readers to a secret realm, inviting us to look behind the big green door for the first time. This generous and loyal friend alerted me to the need for comprehensive overview of American intelligence in World War II.

This anthology is a valuable complement to my first book, with a couple of dozen contributors: a mixture of some who worked at Bletchley Park during the war, and some who are professional historians. The passage of time has encouraged archival research, and allowed historical analysis, producing an authoritative account of Bletchley’s achievements, particularly the breaking of millions of Enigma-enciphered messages.

Carole P. Roman has hit a home run with this nonfiction book. It paints an intriguing picture of the life of spies during World War II. Roman details the training, weapons, and tools used in spy craft. I found the chapters featuring biographical portraits fascinating. Chef Julia Child and author Graham Greene operated undercover. Roman discusses double agents and the Native Americans who broke the Japanese code. I would recommend this book to children who love adventure, espionage, and history. It’s a perfect read for middle-grade students, but an eye-opener for adults as well.

Do I judge a book by its cover? Why yes, yes I do! And the moment I saw this gorgeous cover I put it right into my shopping cart, paid full price, and never looked back.

Luckily for me, Women in Intelligence happens to be an excellent book where the content more than matched the expectations I had from the fabulous artwork. Although there are a few familiar faces that appear, most of the women were completely new to me. Not the femme fatales of popular culture; these were patriotic women who often went unseen in the background.

I love that Fry truly delves into uncovering the unsung heroines of WWI and WWII, giving these quiet, determined women a chance to be recognized and to shine.

In 2018, I went to an author reading by Liza Mundy. Deep into researching my own nonfiction book, I was fascinated as Mundy talked about interviewing women who became code breakers in World War II.

The government recruited them from top colleges and universities, looking for women who were gifted in math and music. The women were sworn to secrecy and kept their word, telling people they had been secretaries during the war. They maintained that fiction into their old age or their graves.

Mundy tracked down survivors and showed them documentation that the program had been declassified. They had been released from their vow of silence and could share their stories with her. The book is excellent.
