Decoding the Devil: Black Women Codebreakers and the Secret War Against Stalin's Bomb

by Sarah Valentine

Decoding the Deviltells the shocking true story of two segregated codebreaking units in the Army's intelligence agencies during World War II and the Cold War.

The result of a racial hiring quota, the Commercial Code unit freed the US from relying on British intelligence on the Axis powers’ trade relations and broke critical Japanese codes.

Led by William Coffee, the unit employed professors, college graduates, and other professionals who decrypted and translated messages from Spanish, German, Italian, French, and Portuguese.

After World War II, the Russian Plaintext Unit countered the growing threat of Soviet nuclear war. A top-secret operation, the all-Black unit worked under armed guard and was the Allies’ main source of intelligence on the Soviet atomic program from 1947 until the early 1950s.

Decoding the Devil highlights the Black cryptologists’ critical contribution to national security in the civil rights era and promises to captivate readers with its fresh perspective on this pivotal moment in American history.

An Important Walk In The Shoes Of “The Other”

I grew up in a white town, went to lily white schools and beamed that I was NOT racist. But here’s the thing. Until I went to university I’d never personally met a black person. My parents hated no one, but had deep, intrinsic racial beliefs that they perpetuated but never recognized.
Now, years later as a senior citizen I have quite a few close black friends who, I believe, understand that I have a good heart, so have seen their way clear to educate me about the daily reality of being black in America. One of their suggestions is to read more.
Books like this one make it abundantly clear that people like me may have nobility of heart, but our understanding of racism is lacking.
This book is very academic, well researched and hard to ignore thanks to the real people we get to known in the book.
The setting is the Cold War and spy craft, but the real subject is racism and sexism, and white willingness to remain in the dark about it.
This is an important read.

[MaryLou]

Very uneven read. The history was interesting, but the individual stories sparse. Started out strong, but finished weak. Bogged down with detailed minutiae about procedures used. Repitious, but scanty details, on individuals highlighted throughout the book. It had a lot of potential, but just wasn't a finished work.

“Ethel is more than conversant in the principles of communism-and the dangers of conflating fear and identity. … she knows the parallels, the warning signs of mass paranoia. In her master’s thesis, she wrote about “the black peril” and “the rising tide of color” that alarmists believe is threatening white supremacy. Alarmists who twist equality into encroachment and inclusion into infiltration. The backlash is swift-and violent. Based in fear. Not logic.” Pg. 75

“Ethel Just who was a Howard University language professor led a team of translators in the Languages section connected with Commercial Traffic codes deciphered by the segregated Black (B-3-b) unit at Arlington Hall Station during WWII. Monitored all international traffic, from Tokyo to Berlin.”
“Sheryl Everett Wormley remembers her grandmother Ethel Just as an accomplished scholar and collegiate educator who broke barriers for Black women during the Jim Crow era. With a bachelor’s degree from Ohio State and a master’s from Boston University, Just became dean of women at South Carolina State University around 1950.”
“Genealogical and newspaper archives suggest that the Ethel Just of Arlington Hall was likely Ethel Highwarden Just, a Howard University language professor who married pioneering Black biologist Ernest Everett Just. The couple lived in Washington, D.C., and had three children before they divorced around 1939.”

On October 29, 1948, the Soviet Union abruptly changed its cryptographic ciphers and cut off radio traffic, causing all monitored communication channels to "go dark." Known in intelligence history as Black Friday, this event blinded U.S. codebreakers, crippled American cryptanalysis, and directly led to the creation of the National Security Agency (NSA). [1, 2]

Wanted to like more but several boring parts

[ReclineAndRead]

Book Review: Decoding the Devil by Sarah Valentine is about Black Women Codebreakers and the Secret War Against Stalin’s Bomb.

Let me start by saying. Books like these are always needed. I love when we get a little more about history that we didn’t know existed. This was my first time hearing about these women and the work they did for the military and America. I hope their story continues to be told moving forward.

Sarah did her research to bring light to this story. And I can tell there still so much more to tell. But because of record keeping and the overall treatment of these women during their time, we may not ever know everything. But they took their job seriously and did everything they could to help the mission.

The book is filled with heavy details about the women and war. But the writing flows and makes it easy to read and understand. If you do enjoy history and love finding out new information please check out this book. Thank you Sarah for giving these women a voice.

[Bookreporter.com Biography & Memoir]

In DECODING THE DEVIL, noted author Sarah Valentine presents a revelatory account of little-known but significant American history: the employment of Black American women to monitor sensitive, secret data regarding the regime of the USSR and its efforts to develop nuclear weapons.

In the post-World War II era, computerization was a new phenomenon. Those who utilized its benefits would need to be highly educated, yet willing to work as undercover agents for low pay in harsh conditions and under the pressure of racial prejudice, which was especially prevalent in Washington, DC. Blacks who lived “under constant threat” were likely candidates to toil for what were known as Code Units.

Valentine’s impressively detailed work focuses on four of these indomitable women: Naomi McElwaine, a Purdue graduate; Ethel Just, whose expertise was the German language; Iris Carr, a Texas schoolteacher; and Minnie Kenny, who developed special knowledge of both Chinese intelligence and cybersecurity.

Through their eyes, Valentine depicts grueling workdays spent in specially segregated buildings and basements under armed guard, the complexities of the regulations to be followed, and the punishments that might ensue for disobedience. She offers scrupulous research concerning the era, with reminders of the Ku Klux Klan, the ideology of the Cold War, America’s exploration of the efficacy of nuclear protection and aggression, the effects of such rebellious personalities as African-American actor and activist Paul Robeson, and the prevalence of beliefs that not only were Black people inferior, but that their very blood was a “contaminant.” Perhaps most telling was the official designation of the women’s workplace as the Traffic Processing Division, which was privately referred to by its managers as The Plantation.

Valentine professes a strong personal attachment to the subject matter that she so diligently shares. Beginning with a talent for poetry, she became drawn to Russian literature. After achieving a PhD, she started to explore her experiences as a mixed-race person, composing the award-winning essay (and eventual memoir) “When I Was White.” DECODING THE DEVIL features a plethora of factual material concerning governmental policies, computer complexities, terminologies such as Book Cipher and Machine Cryptanalysis, and brief biographical portraits of such historical figures as Eleanor Roosevelt, Joseph Stalin and Kim Philby.

Readers new to Valentine’s chosen, vividly arrayed portraits of Black women willing to toil on behalf of a nation that generally scorned them, as well as those with inherent interest in the verities of their courageous work, will wish to further explore her literary offerings.

Wasn’t a huge fan of the authors writing style. Thought more of the book was going to be about the codebreakers but it seems that record keeping was horrific back then because they didn’t care about them and of classified work so it’s not in their resumes, which still happens to this day. Which is truly unfortunate. Would’ve loved to learn more about them, their thoughts, more about the work they were doing. I did really appreciate the examples of what the codes may have looked like coming in and some examples of Russian words they would’ve been looking for.

I just didn’t really like the random inner thoughts put in, sometimes seemingly at random- which makes it seem jumpy and repetitive at times. For example, a paragraph about plaintext, a paragraph about racism that had nothing to do with the plaintext, and then a continuation paragraph about the plaintext.

I also forgot how much the Cold War pisses me off. It’s truly one of the dumbest wars we’ve had. A game of whose dick is bigger and ignorance of what they deemed more important (the bombs over the fact that our men were getting murdered in Korea).

Overall, could’ve been written better but a lot of research was done and a lot of information was provided about the war itself.

[Sarah Valentine]

Not only is this a fantastic book, it's the only book of its kind on this topic. If you love Bletchley Park stories, hidden histories, or Cold War spy thrillers, you need to read this.

Writing this book was a labor of love. Ten years of research, five years of writing, and four years of declassifying documents from NSA means you won't find a more detailed, exciting, and immersive story.

More than just a nonfiction history, it's a story about women. You'll meet inspiring, empowered women doing top-secret work in postwar Washington DC.

To keep the book fast-paced, I made an unconventional choice: The present-tense narrative makes you feel like you're part of the action. Readers say it's novelistic and they're hooked from the first page.

I'm excited to share this passion project with readers all over the world. This book will challenge and entertain you. You'll leave with a whole new perspective on American history and a sense of hope for the future.

[Cathy]

The book's topic is important and interesting, but the execution is terrible. If you are looking for a followup to Hidden Figures, this is not it.

The repetition was mind-numbing. The author also struggles to explain the complex nature of cryptanalysis and the other forms of intelligence. And the book is disjointed. It jumps between historical background, technical descriptions, and vignettes about the women in a dizzying manner. It reads like a rough draft that was rushed off to the publisher.

I admire the effort to shine a light on the racism and misogyny that likely cost the U.S. valuable skills at a vulnerable time. It is unfortunate that even in 2026, we need reminders that choosing the best and brightest regardless of race, creed, sex, or disability is the best way forward. And while the book does an admirable job of pointing out how boneheaded it was to keep these well-educated women in the most menial positions, it isn't engaging enough to really grab the reader.

[Katie B]

Thank you Harper Books for sending me a free advance copy!

3.75 stars

Codebreaking is something I’ve had an interest in and over the years I’ve read a handful of nonfiction and historical fiction books on the subject. DECODING THE DEVIL is a rather unique nonfiction read as it looks at the contributions of Black women in this area of expertise during World War 2 as well as the Cold War era. They were overworked, underpaid, subjected to menial tasks far below their capabilities, and segregated from white units. Finally, decades later they are getting some sort of recognition for their hard work.

Given the secretive nature of the job and classified information, it’s doubtful we will ever get the full story of all the Black women codebreakers. The author did a good job piecing together as much as she could and paints the picture of how it was a thankless job for these women. They got zero support. It was a tough, hostile, and racist environment and given it was a government job, that’s even more shameful.

In addition to highlighting some of the codebreakers, the author goes into the different laws and policies that screwed over Black people during this time. Hundreds of Black families were displaced after their homes were torn down in order to build the Pentagon. Wage discrimination was a huge issue. While this book is informative on the codebreaking side it’s also a worthwhile read for learning more about the uphill battles Black people faced during this era.

[Lauren | TransportedLFL]

Thank you to Harper for the free book. These opinions are my own.

I think it is so important to learn about the aspects of history that are not as frequently shared. I am glad to have read this story of Black women codebreakers. It's set in the wake of World War 2 during the Cold War.

This nonfiction is very well researched and grounded in fact. Yet it reads like fiction at times. The prose is incredibly engaging. We follow the stories of multiple women throughout their careers. In writing this, the author lays out both the individual and the broader context.

I can't say I am fully surprised to learn about the segregation and poor treatment, continuing long past when both were illegal in the federal workforce. Moreover, there is the intersectionality of dual discrimination that Black women face. And I am not all that surprised that such unethical choices also were poor management decisions that made it harder to gain intelligence and protect national security.

I'm grateful to Sarah Valentine for her work in uncovering and sharing these histories.

[Patrick]

This is a hard one to review. The book is very well researched, and makes a strong case for the appalling waste of human talent that racism and just plain stupidity caused in the intelligence community. The book is at its best describing the personal cost of racism, and the maddening frustration of being intelligent, talented, and hard-working but held back by a deeply broken system.
Unfortunately, the work is severely undermined by endless repetition of the main points about organizational dysfunction and lack of strategic vision. At times I felt as though there were about 50 to 100 pages of substantive material that was stretched into 200 pages. The author clearly needed a stronger editor.
It's worth reading to appreciate the history she reveals, but you may find yourself skimming parts of it.

[Chester Gipson]

This book is MUST READ. One of the book's greatest strengths is its focus on individuals who have received little recognition despite their significant contributions to national security. Valentine highlights the experiences of highly educated Black women who worked under difficult conditions, facing racial segregation, geometry dash spam, wage disparities, and limited opportunities even while performing critical intelligence work. The book succeeds in combining espionage history with social history. Rather than presenting codebreaking as a purely technical subject, Valentine explores how race, gender, and politics intersected within the intelligence community.

[Magic_of_books]

This was a fantastic read, thanks to the publisher for sending me a copy via a giveaway. After reading Hidden Figures some years ago, I became very interested in learning more about unsung women of color who made a difference in advancing science and technology. This book was a perfect addition to my shelf. I am so glad I got to learn about the critical role played by Black women codebreakers for the security of the United States at a time when segregation and racism were prevalent in ways we cannot imagine today. Will definitely be recommending this for book clubs, especially for Women's History Month!

[Gregg Preston]

Let me start by saying. Books like these are always needed. I love when we get a little more about history that we didn’t know existed. This was my first time hearing about these women and the work they did for the military and America. I hope their story continues to be told moving forward.

But they took their job seriously and did everything they could to help the mission.

[Bonnie]

This is an interesting book and what it revealed about how the black women employed by the federal government was (unfortunately) not very surprising but still infuriating. The worst thing that happened to this country (in my opinion) was the introduction and use of slavery. It has stained this nation's reputation and caused suffering and continued bad relations among the races.

The reason I give this book three stars in spite of the fact that it is well-written, is that it wasn't quite what I was expecting, which was more about how and what these women decoded during Stalin's reign.

[J Leon]

This book was surprisingly novelistic. Even though it is grounded in historical events the women's lives carry the narrative, making it an extremely compelling read. They face unimaginable hardships but are inspiring in what they were able to accomplish, inside and outside of the NSA.

On a genre note, I didn't know much about codebreaking before reading this book, and I was glad that it wasn't too technical. The book includes a detailed glossary with people, places, events, and specialized terms at the end, which I found very helpful. Great summer read, highly recommend.

[Becky Z]

Not what I had hoped to learn about the actual work performed and the critical information attributed to these ladies. Much more about Jim Crow South and segregation perpetuated in a methodical way. Pentagon & Washington DC background interesting but not what I wanted from the book.
However, I believe the author made a valiant effort to retrieve what is available and believe most was buried or lost due to the nature of the women being Black.

[Israel]

Decoding the Devil is a powerful reminder that some of the most important stories in history are the ones left untold.

I found the stories of these Black codebreakers especially compelling; their intelligence, skill, and quiet contribution to national security, despite working within a deeply segregated system. Sarah Valentine brings a hidden chapter of wartime and Cold War history into the light, making this both an informative and thought-provoking read.

[Daniel Tepfer]

In an early chapter discussing the buildup following Pearl Harbour, the author mentions rhat RCA iis concentrating on rhe manufacturer of tubes and transistors. Transistors were invented in 1947 by Bell Labs. A second reference to the manufacture of transistors during WWII is made in section 2 trade secrets. What kind of research did the author make for this book?

[Russell]

Though the book seems well-researched, I just found the writing style (and number of typos in the first pages) off-putting, so I quit reading it. Too bad, because the subject matter is one that normally interests me.

[Juli Benko]

This fascinating history of Black female codebreakers during the Cold War highlights both their critical intelligence work and the infuriating reality of deeply rooted racism they faced.
