Product Description

From Amazon

At the age of 8, Leo Marks discovered the great game of code-making and -breaking in his father's London bookshop, thanks to a first edition of Poe's The Gold-Bug. At 23, as World War II was being played out in earnest, he hoped to use his strengths for the Allies. But Marks's urgent, witty memoir, Between Silk and Cyanide, begins with his failure to get into British Intelligence's cryptographic department. As everyone else on his course heads off to Bletchley Park ("the promised land"), he is sent to what his sergeant terms "some potty outfit in Baker Street, an open house for misfits." In fact, the Special Operations Executive's mandate was, in Churchill's stirring phrase, to "Set Europe Ablaze," and Marks's was to monitor code security so that agents could could report back as safely as possible. When he arrived, the common wisdom was that it was easiest for men and women in the field to memorize and use well-known poems.

Unfortunately, since the Germans had equal access to the classics--"Reference books," Marks quips, "are jackboots when used by cryptographers"--Marks thought agents should write their own poems (or use his) instead, several of which are cheerily obscene. After all, no son or daughter of the Fatherland could ever know the rest of a verse that began "Is de Gaulle's prick / Twelve inches thick," and continued on in a similar, shall we say, vein. But Marks soon felt that original doggerel was just as dangerous, since even slight misspellings could render messages indecipherable and risk agents' lives. His first solution? WOKs (worked-out keys) printed on silk. An operative would use one key, send the message, and immediately tear off the strip. Marks had a hard time proving that swaths of silk would save his people from swallowing their "optional extra," a cyanide pill. His efforts were dead serious, but often landed him in comic terrain.

In one of the book's great set pieces, Marks visits Colonel Wills--surely the model for Ian Fleming's Q--in order to sort out the best ways to print his code keys. Before solving this minor problem (invisible ink!), Wills showed Marks several new projects--one of which involves an exotic array of dung, courtesy of the London Zoo. This gifted gadgetmeister planned to model life-sized reproductions of these droppings and pack them with explosives, personalized for all parts of Europe, Africa, and Asia. "Once trodden on or driven over (hopefully by the enemy) the whole lot would go off with a series of explosions even more violent than the ones which had produced it," Marks explains.

Despite such larky sentences and sections, the author never loses sight of the importance of his vocation, and Between Silk and Cyanide is as elegiac as it is engaging. Marks knows when to cut the laugh track, particularly as his book becomes a despairing record of agents blown--lost to torture, prison, the camps, and execution. Readers will never forget the valor of Violette Szabo, Noor Inayat Kahn, and the White Rabbit himself, Flight Lieutenant Yeo-Thomas. Poem-cracking, as Marks again and again makes clear, was far more than a parlor game. --Kerry Fried

From Publishers Weekly

A well-paced war diary, Markss memoir traces the strategically vital creation of secure codes for Allied agents operating in Nazi-occupied territories. Marks was in his early 20s during the war, a civilian with military rank in Britains elite Special Operations Executive, a prodigy immersed in a pasty world of subterranean old men. Though Marks rarely ventured out of his basement office, his book builds a delicate tension as he describes working frantically to develop codes that the Nazis could neither crack nor imitate, as they did with the standard Allied poem code. Markss contributions to such historically significant events as the destruction of Norsk Hydro, the heavy water plant on which the Germans pinned their hopes for atomic weapons, and to the concealment of preparations for D-Day, are effectively balanced against such workaday concerns as finding quantities of silk onto which codes could be photographed. Although Markss account is more anecdotal than researched, his unique position as chief developer of Britains secure communications, along with an impishness that led him to break De Gaulles secret French code (off-limits to the non-French Allies) or rib his older compatriots (Davies nodded so hard he almost lost a jowl) give his book an authoritative and laconic punch.

Format: Paperback
Leo Marks' book of memories of working as a cryptographer with Allied agents for the Resistance during the Second War is compelling for many reasons. The average life expectancy of a wireless operator in France in 1943 was 6 weeks, and Leo improved procedures in many ways to help keep them safe, including devising ideas such as using Codes printed on silk, which would be burned immediately after use. And remarkably, he did this at the age of 22.

The title refers to his request for silk from his superiors in the War Office (silk was very hard to come by), stressing the importance by commenting that the choice for these agents was 'between silk and cyanide'.

The current system involved using well-known poetry as a Code; since this was easy for Germans to break, Leo started writing original poetry for use as Codes. And one of the most engaging items in his story are the poems he wrote, including "The Life That I Have", which has deservedly become well-known.

I found this book so fascinating that I am reading it for the second time. He writes with self-deprecating humour and a love of life.

This is quite a lengthy book, about 600 pages, and at times it does seem to drag on. The topic itself is quite interesting--during WWII, the author at the young age of 22 shows himself to be a brilliant codemaker/codebreaker, and eventually rises to the highest levels, despite his unconventional relations to authority figures. The book is not really about coding, however.
The book presented a side of WWII that is not often heard--that of the courageous agents dropped into occupied territory to sabotage and to prepare the Resistance for D-Day. It was especially sad to note that often the author, while preparing them for deployment, knew that their capture by the enemy was imminent, because the enemy had already captured many of their comrades and was forging messages back to London in their names--however, Marks' superiors were unwilling to acknowledge this, for reasons which remain in debate to this day.
I have to agree with many of the other reviewers on several points. Marks' wit, while humerous at times, does tend to get old by the end of the book. The author was unnecessarily vulgar at times, as well. In addition, it was sometimes tedious to wade through all the acronyms and code-names.

First I must say this: if you have any interest in the interaction between, on the one hand, people willing to sacrifice themselves for their beliefs and their country, and on the other, office-political self-interest, read this book if you can. As an eye-opener, it bitterly counter-echoes Macaulay's "None were for the party, all were for the state." Irrespective of anybody's opinion, adverse or otherwise, read it if you want unusual material on several subjects, including Giske's masterful exploitation of his penetration of the WWII Dutch resistance. Read it also if you simply are interested in cryptology, the history of cryptology or the development of cryptology (or of cryptologists). Read it if you want a vivid portrayal of the fog of war as seen from the back room, the frustration, the obsession, the pressures, the fear and the grief. Prepare yourself to control your blood pressure if you have views (from EITHER perspective) on the subject of boffin versus boss. The book is a primary and secondary document of great interest.
"Between silk and cyanide" includes plenty of humour of all shades, mainly dark, but don't read it for fun unless you are totally insensitive; it deals with harrowing events in harrowing times and I found it very upsetting on several levels. It would be wasteful to read it in a hurry just because you are a fast reader. This is a labyrinth of a book and there are many mazes of twisty little passages, all alike, that you very likely will miss if you are not careful. Heaven knows how many I myself skated over in my innocence.
This is a large book, but that is not why it is not to be read at a sitting. Nor is the reason that it is hard to read; I had to stop repeatedly to rest and to digest (or recover from) the situations and implications described.

This book is a witty, and compelling memoir of Great Britains cryptographic war against the Germans. It was written by code- breaker Leo Marks. Son of the proprietor of the famed bookshop at 84 Charing Cross Road. In spite of being written with a light hand, I found this book to be an interesting, moving and at times downright chilling account of the little-known SOE intelligence section as seen by the author as a brilliant and brash 22 year old prodigy whose job was to monitor code security so that agents in occupied Europe could report back as safely as possible.
Though Marks rarely ventured out of his basement office, his book describes how he worked frantically to develop codes that the Nazis could neither crack nor imitate. I would however, be interested to read an account of what went on in the SOE during these years from his supervisor’s POV. I suspect that their accounts would be slightly different since over years memory can become very selective and self serving. I think that Marks with his tendency to ignore rules, to act on his own based on his own understanding of events, while well meaning, often did not take into account that he may not be aware of the whole picture. He must have caused the people in charge of SOE many a sleepless night. The term loose cannon comes to mind here.
The parts that broke my heart was account of the agents who were “blown,�lost to torture, prison, the camps, and execution. I will never forget the accounts of Violette Szabo, Noor Inayat Kahn, the girl who could not lie and Flight Lieutenant Yeo-Thomas, known as The White Rabbit. The incredible bravery of these people just cannot be imagined.
