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.

This is a book that is at once a biography, a testament to human genius in the face of imminent danger, and a story of human injustice. Alan Turing had an idea about a ‘universal machine’. A machine, when built at Bletchley Park, allowed the Allies in World War II to crack the German Enigma ciphers. This universal machine laid the foundations for modern computing and all the amazing advances we enjoy today. But at a price for Turing, he fought inner demons about his homosexuality and eventually paid the ultimate price.

I marveled at his genius, cheered his cryptographic successes with each cipher cracked, shouted against the tragedy of his arrest, cried at his untimely death. A death at his own hand at the age of 41. The world lost a genius due to a society’s labelling of homosexuality as a crime.

We still live in this world of… show more.

The brilliance of the Bletchley Park codebreakers is undoubted, but it must be remembered that they did not start from scratch; they built on the work of the cryptanalysts of the Polish Cipher Bureau, who had first broken Enigma ciphers in 1932, and then passed on all their knowledge to Britain in 1939, before the war began. The tentative and suspicious negotiations between Poland, France and the UK were convoluted and lengthy. Alan Turing’s nephew conducted ground-breaking research in archives in the UK, France, Germany, Poland and the USA to compile this unrivalled account of those early days.

At my presentations, I am so often asked ‘Didn’t the Germans know the Allies had broken Enigma?’ and ‘Did Germany have something like Bletchley Park?’ This book answers questions like these, and shows, in particular, the unjustified faith the Germans had in the Enigma machine. Believing its ciphers to be unbreakable, they failed to spot evidence of its weaknesses and vulnerability.

Intelligence was collected in multiple ways by all sides during World War II. The British housed German prisoners at a site called the London Cage, which was located in an upper-class London neighborhood. The London Cage was later used as a Nazi war criminal detention site. While in residence, the German prisoners underwent interrogation, in some cases what we would now call “enhanced interrogation” and in others while under the influence of “truth drugs.” As Fry’s book reveals, the post-9/11 “enhanced interrogations” were not the first of its kind. I recommend this book because it demonstrates the lengths to which governments, in this case the British government, would go during wartime to gather actionable intelligence about an enemy.

A thrilling personal account by the brilliant cryptographer, Leo Marks, who was only 22 when employed by the SOE. It was Marks who gave the special codes to famous SOE agents like Violette Szabo, Noor Inayat Khan, and Nancy Wake before they left for the field. An insight into how the code war between Germany and England played out, often with disastrous consequences.

Harry Cole was a criminal who grew up in an East London slum. In 1939 and fresh out of prison he enlisted in the army, before absconding with the mess fund. As France fell, he had a shot at redemption—and having been left behind after the evacuation at Dunkirk, set about organising escape lines. His ability to outwit the enemy made him a star of the various resistance and special operations networks, but shortly after capture in 1941 he began to betray every contact he had made in France.

Murphy’s book is unlike any other wartime biography. It plays out like a gripping piece of fiction. It shows too that while we might comfort ourselves ‘we’ were the good guys in WW2—we had plenty of very bad guys among us. Makes you look at WW2 through a different prism.

John Masterman’s diary of events as head of the Committee which orchestrated the Double Cross Deception of the Second World is a classic read. The British ran an elaborate network of around 120 double agents whom German Intelligence believed was working for the Third Reich, but in fact were being controlled by MI5—the British Security Service responsible for security and counter-espionage within Britain. The handling of these double agents, around 120 in total, was the responsibility of the Twenty Committee (XX), otherwise known as the Double Cross Committee. It was chaired by Masterman, the fifty-year-old ex-Dean of Christ College, Oxford.

Some of the wartime double agents had originally landed in England as German spies had been captured and ‘turned’ to work for MI5. British handlers, including at least one woman, ran double agents like Garbo, Zigzag, and Tricycle. These double agents passed false information to the German Secret Service and… show more.

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… show more.

The key to a successful historical thriller is a strong sense of time and place, but not so strong that it slows down the plot – it’s still a thriller after all, and while it’s so tempting to find somewhere to put all that research, discipline is essential. I loved this book because Robert Ryan does it particularly well. I took a lot from it for The Fulcrum Files, particularly the mix of action and romance and the basis in real events.
