Book cover of 'Blinker' Hall: Spymaster: The Man Who Brought America into World War I

Roseanna M. White Author Of The Number of Love

From my list on British intelligence in WW1.

Why am I passionate about this?

Roseanna M. White is a historical fiction writer whose bestselling stories always seem to find their way to war, espionage, and intrigue. A fascination with her family’s heritage led her to tales set in Edwardian and Great War England, and she’s spent the last seven years studying that culture and how the era’s events intersected with things like faith, family, the arts, and social reforms. Of course, she does all this study and writing about war and mayhem from the safety of her home in West Virginia, where life is blessedly ordinary and no one expects her to actually crack any codes in order to survive...which is definitely a good thing.

Roseanna M. White Why did Roseanna love this book?

Any research into the codebreaking arm of British Intelligence during the Great War will quickly point to one man as the mastermind: Admiral Sir Reginald “Blinker” Hall. He is, at a glance, one of the most intriguing historical figures you’ll ever come across…and the more you learn, the more convinced you’ll be of that. In Blinker Hall, Spymaster, Ramsay delivers not only a thorough look into intelligence and codebreaking, using documents that have been declassified only recently to his writing, but also an insightful look into the man who orchestrated one of the most complex intelligence systems of the modern era. For anyone interested in intelligence, cryptography, or even just the invisible world behind a war that spanned continents, this book delivers it all, and does it in an engaging, entertaining style.

What is this book about?

Admiral Sir Reginald 'Blinker' Hall, the Director of Naval Intelligence (DNI) for most of the First World War, described as 'a genius in his own sphere and brilliantly successful', was one of the outstanding if largely unrecognized naval leaders of that war. Naval intelligence's ability to read and analyze German naval and diplomatic signals on a daily basis was a significant factor in the allied victory. The Germans never realized that their codes had been broken. The revelation of the Zimmermann Telegram, depicted as one of the most exciting events in the history of intelligence, astutely handled by Hall, was…


Book cover of Slow Horses

Bruce Borgos Author Of The Bitter Past

From my list on a protagonist who has extraordinary capabilities.

Why am I passionate about this?

I’ve always loved peculiar heroes and heroines. Characters with strange gifts and an equal number of challenges. It started with Sherlock Holmes, whose mind fascinated me. As a child, I gravitated to the unnatural protagonist, Tarzan, in the Edgar Rice Burroughs novels and Bilbo Baggins in The Lord of the Rings trilogy. I was never a big fan of Superman, I preferred people who adapted quickly to new surroundings and could think on their feet. Once I began my writing career, I kept those protagonists in my mind. Four novels in, I do my best to capture their spirit and determination to overcome whatever lands in front of them.

Bruce's book list on a protagonist who has extraordinary capabilities

Bruce Borgos Why did Bruce love this book?

I loved this book because it’s about misfits. In this case, misfits who are spies. Spies who have screwed up and disgraced themselves and their masters at the British Secret Service. They’re led by the disheveled and malodorous Jackson Lamb, who is so smart he disdains everyone around him.

He and the Slow Horses get all the bad assignments, but I loved how each of them possessed special skills and a desire to redeem themselves. I think Mick Herron is the master of humorous spy fiction!

Slough House is the outpost where disgraced spies are banished to see out the rest of their derailed careers. Known as the 'slow horses' these misfits have committed crimes of drugs and drunkenness, lechery and failure, politics and betrayal while on duty.

Larry Enmon Why did Larry love this book?

Have you ever finished a book and been saddened that it ended? That was my experience with this book.

Herron put a diverse cast of characters in an exciting place, doing exciting things, and, for good measure, threw in murder. Those of us who love the spies from Britain's MI5 (Slow Horses) series also love how they interact, not always in a good way.

Herron removed them from their comfort zone in London and dropped them into the Welch countryside during a winter blizzard. I love that, and it's precisely what I did in my book. You create tension and suspense by removing the central characters from their familiar surroundings to a strange, unfamiliar place.

Book cover of The Unlikely Spy

Cristina Loggia Author Of Lucifer's Game: An Emotional and Gut-Wrenching World War II Spy Thriller

From my list on World War 2 for people who love history and fiction.

Why am I passionate about this?

I am a former journalist and corporate public relations expert with a Ph.D. in Foreign Languages, I’ve always been passionate about World War 2 history and truly fascinated by the deceptions put in place by both the Allies and the Axis. I believe that a story that mixes fiction with history is highly powerful and evocative. I set my debut novel in the Rome in 1942 because I was inspired by the numerous stories heard from both my grandfathers who fought in the war and because Fascist Italy is not as well-known as it should be. As one of the very few female thriller writers in this genre, I wanted to celebrate the contribution of women in World War 2!

Cristina Loggia Why did Cristina love this book?

The author clearly did a great deal of research for this book, and this is certainly something I truly love in this World War 2 novel: it provides that solid and rich actual background against which the story is set. It is fascinating to see how both the Nazis and the Allies were playing a game of deception, trying to outmanoeuvre and outsmart each other. The writing is very good, the characters are complex, all with their flaws, all very interesting indeed, all feeling very credible, real. An engaging spy thriller that remains one of my favourite in this genre.

Book cover of Roosevelt's Secret War: FDR and World War II Espionage

Patrick W. O'Bryon Author Of Corridor of Darkness

From my list on espionage and resistance in Hitler's Third Reich.

Why am I passionate about this?

While a graduate student and then an army interpreter in Germany, I listened to reminiscences from both Third Reich military veterans and former French resistance fighters. Their tales picked up where my father's stories of pre-war European life always ended, and my fascination with this history knew no bounds. On occasion I would conceal my American identity and mentally play the spy as I traversed Europe solo. A dozen years later upon the death of my father, I learned from my mother his great secret: he had concealed his wartime life as an American spy inside the Reich. His private journals telling of bravery and intrigue inspire each of my novels.

Patrick W. O'Bryon Why did Patrick love this book?

If you love reading the history of World War II espionage, Persico brings to life behind-the-scenes maneuvers that took America from an unwieldy group of intelligence-gathering organizations to the formidable Office of Strategic Services under Wild Bill Donovan. While examining all theaters of World War II rather than just the Third Reich, the author provides excellent insights into the specific challenges encountered in Hitler's realm. I particularly enjoyed learning how Roosevelt balanced the information coming from many sources and integrated that knowledge into an intelligent plan of action.

Despite all that has already been written on Franklin Delano Roosevelt, Joseph Persico has uncovered a hitherto overlooked dimension of FDR's wartime leadership: his involvement in intelligence and espionage operations.

Roosevelt's Secret War is crowded with remarkable revelations:
-FDR wanted to bomb Tokyo before Pearl Harbor
-A defector from Hitler's inner circle reported directly to the Oval Office
-Roosevelt knew before any other world leader of Hitler's plan to invade Russia
-Roosevelt and Churchill concealed a disaster costing hundreds of British soldiers' lives in order to protect Ultra, the British codebreaking secret
-An unwitting Japanese diplomat provided the President with…

Ray C Doyle Author Of The Defector's Diary

From my list on mystery thrillers ripped from news headlines.

Why am I passionate about this?

I guess my real interest in writing about the good and bad in crime and politics and the good and bad characters involved started with my first job as a junior in a local newspaper. The 60s was a time of great change. I was in the right place at the right time and got involved in reporting local government politics. I graduated later to cover Britain’s role within the EU in Brussels. I was fascinated, not so much by the politics but by the politicians and fellow news reporters involved. They inspired the creation of my fictional character, Pete West, a hardboiled political columnist.

Ray C Doyle Why did Ray love this book?

Read as a teenager, this book hooked me into mystery thrillers. It has everything from murder to political intrigue to a spy ring.

The book is a chase thriller with twists, turns, and surprises. Written in 1930, the work had the feel of a ‘boy's own’ adventure story with a man on the run hunting German spies and clues leading to the 39 steps and victory.

Great story!

But then a murder is committed in his flat, just days after a chance encounter with an American who had told him about an assassination plot which could have dire international consequences. An obvious suspect for the police and an easy target for the killers, Hannay goes on the run in his native Scotland where he will need all his courage and ingenuity to stay one step ahead of his pursuers.

Jenny Harrison Author Of Dead Before Curfew

From my list on the human cost of war.

Why am I passionate about this?

My name is Jenny Harrison and my writing career started in 1997 in South Africa with Debbie's Story, which to my astonishment, became a bestseller. Thinking this was going to be an easy route to fame and fortune, I continued writing after migrating to New Zealand. Alas, the road to a bestseller is rife with disappointment but that didn't stop me from writing a bunch of paranormal and humorous novels. Circumstances led me to writing about families caught up in World War II. I don’t write about battles or generals, I write about ordinary people who face the unimagined cost of war and survive.

Jenny Harrison Why did Jenny love this book?

This book is by Alan Furst whose research is impeccable. His storytelling can be jerky and maybe chaotic but that’s how things were in the time he writes about. His characters are drawn from the sinister underbelly of war, the men and women who work in the shadows. His writing is intense, I remember the scenes as chaotic, with no character arc or happy ending, but a mirror of the times when life was lived moment by moment.

What is this book about?

September 1939. As Warsaw falls to Hitler’s Wehrmacht, Captain Alexander de Milja is recruited by the intelligence service of the Polish underground. His mission: to transport the national gold reserve to safety, hidden on a refugee train to Bucharest. Then, in the back alleys and black-market bistros of Paris, in the tenements of Warsaw, with partizan guerrillas in the frozen forests of the Ukraine, and at Calais Harbor during an attack by British bombers, de Milja fights in the war of the shadows in a world without rules, a world of danger, treachery, and betrayal.

Helen Fry Why did Helen love this book?

The official history of MI5 similarly provides the first authorised account of another secret organisation. The book provides a far-reaching account of clandestine activities since its nascent beginnings as part of the Secret Service Bureau in 1909, and across a period of 100 years. It offers a rare insight into some of the eyebrow-raising operations in counter-espionage, as well as an administrative overview, for an intelligence agency that is responsible for Britain’s security at home. It gives the first inside account from it archives, from Bolshevik threats and Communist subversive activities in the 1920s in Britain to Hitler’s spies in the 1930s, to the Double-Cross deception and agents of World War Two. It goes beyond the Second World War to name some of the traitors and spies of the Cold War. There is a clear understanding publicly for the first time of the sheer scale of surveillance of enemies or…

For over 100 years, the agents of MI5 have defended Britain against enemy subversion. Their work has remained shrouded in secrecy—until now. This first-ever authorized account reveals the British Security Service as never before: its inner workings, its clandestine operations, its failures and its triumphs.


Book cover of Threat on the Horizon: An Inside Account of America's Search for Security After the Cold War

David P. Oakley Author Of Subordinating Intelligence: The DoD/CIA Post-Cold War Relationship

From my list on history, personalities, activities of intelligence.

Why am I passionate about this?

My fascination with intelligence studies is tied to my previous experience as a practitioner. While serving as a military officer and CIA officer, I became curious about how two organizations with a shared history could be so different. Exploring the “why” of the CIA/DoD differences led me to the broader interplay of organizational cultures, individuals, and missions in influencing the evolution of intelligence, its purpose, and its role. These five books will provide the reader a broader appreciation of how intelligence was used to help policymakers understand reality and how intelligence organizations have been used to try to change reality. You will not merely learn something about intelligence but will be entertained and engaged while doing so.

David P. Oakley Why did David love this book?

The decade between the end of the Cold War and the beginning of the Global War of Terrorism was a decade of uncertainty for the U.S. intelligence community and an important part of intelligence history. The collapse of the Soviet Union and the reduction in national security budgets raised numerous questions about the purpose, focus, and funding of intelligence organizations during the 1990s. Loch Johnson’s book is an excellent and essential read to understand this period. One of the foremost intelligence scholars, Johnson also served on the Aspin-Brown Commission that considered the future of U.S. intelligence after the Cold War (he also previously served on the 1975 Church and Pike Commission). A commission covered extensively in this book.

The Aspin-Brown Commission of 1995-1996, led by former U.S. Defense Secretaries Les Aspin and Harold Brown, was a landmark inquiry into the activities of America's secret agencies. The purpose of the commission was to help the Central Intelligence Agency and other organizations in the U.S. intelligence community adapt to the quite different world that had emerged after the end of the Cold War in 1991.

In The Threat on the Horizon, eminent national security scholar Loch K. Johnson, who served as Aspin's assistant, offers a comprehensive insider's account of this inquiry. Based on a close sifting of government documents and…

Why am I passionate about this?

Dr. Mark Baldwin – aka Dr. Enigma – is a world expert and speaker on the Enigma machine and has delivered over 700 presentations and demonstrations (using his own, genuine wartime Enigma machine) to some 70,000 people around the world. He has spoken to a wide range of audiences, from cybersecurity experts and software developers at leading Silicon Valley tech companies such as Facebook, Dropbox, and PayPal, to academic audiences at universities, executives at business conferences, and the general public in a couple of hundred one-man theatre shows.

Mark's book list on the Enigma Machine and Bletchley Park

Mark Baldwin Why did Mark love this book?

The Enigma story and Bletchley Park are now legitimate subjects for academic study, but modern books are necessarily written by people without first-hand experience of wartime Intelligence work. As a publisher, I have always been keen to record the experiences of those people personally involved in such things, and Welchman was not just a leading codebreaker at Bletchley Park throughout the whole war, he was also instrumental in transforming a random collection of a hundred academics into a non-stop production line of codebreaking and Intelligence, employing over ten thousand people. This, our best-selling book, continues to intrigue readers worldwide.
