The Puzzle Palace: Inside the National Security Agency, America's Most Secret Intelligence Organization

by James Bamford

In this remarkable tour de force of investigative reporting, James Bamford exposes the inner workings of America's largest, most secretive, and arguably most intrusive intelligence agency. The NSA has long eluded public scrutiny, but The Puzzle Palace penetrates its vast network of power and unmasks the people who control it, often with shocking disregard for the law. With detailed information on the NSA's secret role in the Korean Airlines disaster, Iran-Contra, the first Gulf War, and other major world events of the 80s and 90s, this is a brilliant account of the use and abuse of technological espionage.

In the beginning, the NSA did not exist: though President Eisenhower created it in 1952, its very existence, not to mention what it did, was kept secret. Now, secrecy isn't necessarily a bad thing, but on the face of it you have to suspect something is amiss in such cases. As my parents would've said to me (and maybe did at some point), if you have nothing to worry about, why hide?

This was a provocative, informative, and valuable book when I read it, which I believe was during the late 1980s, and it has become so again in 2013, as anyone who's been following the news in America is bound to realize. Bamford gives some background on intelligence gathering, reporting for instance that, when a certain form of snooping was proposed to Secretary of War Henry Stimson earlier in the 20th century, he answered by declaring that gentlemen do not read each other's mail. The issue wasn't new at the time; in June of this year, a New Yorker article by Jill Lepore found a similar situation back in 1844, when a debate arose in Britain over the opening of Giuseppe Mazzini's mail. Apart from bits of history, though, Bamford mainly reports on what the agency does and how it works. Its purview is basically anything other than human intelligence (HUMINT, in the government acronym), meaning it doesn't put people in the field to find out things; instead, it gathers information through other means.

The technical details, depending on your background, may make you envious of NSA employees. Some of them get to spend the day playing with cryptography of every sort, while others get every new supercomputer that comes along. Machines that were practically mythical to ordinary techno-geeks, such as those devised by Seymour Cray, were always to be found at the NSA. Other parts of Bamford's story add colors and shadows to the picture; we learn, for instance, of an elaborate and very costly waste-disposal system, built to keep anyone from sifting the NSA's trash, that failed ever to work. And I seem to recall a mention of the capture of the USS Pueblo spy ship. (My memory is admittedly incomplete and imperfect. For this review I haven't consulted the book or any commentary on it, other than something I'll mention shortly.)

What I don't remember the book doing is giving much contemporary context. America isn't the only country that spies; what do the others do? No doubt it'd take an entire book to deal with each of the world's more developed countries, so you can't be surprised if Bamford leaves the issue alone. But surely it matters, at least in a practical way.

A recent post on The New Yorker's Page-Turner blog gave some nifty information on James Bamford, this book, and the handful of others on the NSA with which he followed it. I recommend it.

The puzzle palace is getting a little old, but it still applies. The NSA is one of those government agencies that everybody knows about, except if you ask them what they know they scratch their head and say "not much." Much of the computer things we take for granted today from encryption to managing large data streams, to cloud computing and managing large networks to modern telecom routers was invented at or encouraged by NSA if the truth be known. Puzzle Palace was one of the first books about NSA and their are others now - but this is a good place to start.

[Omar Manejwala · Rating 5 out of 5]

Truly mind-boggling. I was blown away when I learned how much the NSA has done over the last few decades...really a page turner. Plus I grew up near there and never quite knew what it was. This is as thrilling as a spy novel with the added shock factor of being true.

Recent revelations regarding massive data mining of phone and Internet activity (hello Uncle) reminded me of this read. Published in 1988 and read by me in perhaps early 2000's, the book lay out NSA's Hugh accumulation of computing power. Before even Bush era legal authorization this data was being collected and all foreign contacts swept for key words, slang, repeated unknown phrases - names, dates, locations.

I recall numerous newspaper references to criminals and suspected terrorists contacts overseas, for example, within three days of Boston bomb newspapers were making references to suspects phone contacts. What do people think? How would this info be available otherwise?

There have been a number of other news articles regarding terrorists in Michigan, somewhere in the south. Some have been phone activity and some Internet.

The idea that this is new news surprised me. I've been thinking this was the case since ColIntelPro.

The basic idea here is don't do anything wrong and don't talk to anyone if you do. The scarier idea is don't disagree with the powers that be, but that has always been true.

[Ericka Clou · Rating 3 out of 5]

This book is sometimes surprising, often boring, and extremely quaint. The entire idea is how secretive the NSA is, and how few people even know that there is an NSA or what it has done. Oh, remember before Russia hacked our election in multiple different ways and NSA officials and ex-officials testified before Congress on television several times? Those were the good old days!

The National Security Agency is a U.S. government agency responsible for gathering and analyzing signals intelligence. In 1982, the NSA was far less known than the CIA and other alphabet agencies, but it had no less lurid a history. In 1958, a US Air Force-NSA surveillance plane invaded the airspace of Soviet Armenia, and was shot down by MiGs; all 17 crew were killed; neither government admitted to the incident publicly. In 1967, a US Navy-NSA surveillance ship observing the Six-Day War was attacked by Israel, 34 crew were killed and 170 wounded before the Israelis realized their mistake; Bamford says that the official US-Israeli story about the attack doesn't hold water; I've read an article claiming that the theory that the attack was deliberate has its own set of problems. The NSA was infiltrated by Soviet spies; a British double agent was also a pedophile who built up a catalog of over 2000 index cards about local teenage girls; when he was arrested for sex offenses, a house search found his spy kit. The NSA worked hard to prevent the spread of cryptology; its head wanted a monopoly on cryptologic research, like the Department of Energy has a monopoly on nuclear research. Bamford says that the NSA made IBM reduce the length of the DES key from 128 bits to 56 bits; I've read before that the reduction was from 64 bits to 56 bits; cryptome.org claims that it tried to make IBM reduce it from 64 bits to 48 bits, but they compromised on 56 bits - I wondered for years, why it is such a non-round number. Professors Diffie and Hellman claimed that a DES cracking machine could be made for $10 million; two IBM engineers argued that the cost would be closer to $200 million; in 1998 enthusiasts built a DES cracking machine for $250 thousand. Something I did not know before is that no US President bothered to repeal Truman's 1950 national emergency until September 1978; so in April 1978 the NSA could attempt to suppress a Seattle inventor's cryptographic telephone on the grounds of a national emergency.

Too much data to be light reading. Very well researched. Amazing how much information is available that the Media ignores.

Well researched... poorly written.

[Georgia Swadling · Rating 3 out of 5]

picked this up and started reading it on a recommendation from one of the books i read on edward snowden (i think ?) before i realised it was published in 1983. i tend to avoid older non-fiction as a rule because i get unfairly impatient about it being out of date so that’s on me for not checking.
that said, whilst this is clearly rigorously researched it wasn’t super well written and i struggled at multiple points. there were so many extraneous details on where each small NSA employee went to university and what they studied that i wish someone had taken this guy in hand and let him know you don’t have to include everything that you turn up in your research phase.
the chronology was also a bit strange, jumping back and forth between different key events so i was occasionally lost on what happened first. definitely could do with some restructuring.
that said it was cool getting an insight into the birth and evolution of the NSA and it was really weird hearing it described as this top secret agency no one had even heard of considering where we’re at now where the NSA listening to you is virtually a pop culture reference.
overall probably wouldn’t recommend, they are definitely better written books about the NSA out there but i did learn a few things.

A lot less was known about the NSA and its operations when this book was published back in 1982 then it is today. But while the agency's existence - denied for decades - and some of its highly questionable (to put it mildly) activities have become public knowledge the the decades since, this was still a very informative book. Bamford's account of the NSA's beginnings and history up to the date of publication makes for highly interesting reading.

[Jeff · Rating 4 out of 5]

It's an interesting time (Snowden leaking NSA's PRISM program) to read about the history of the NSA. Even though this book was written back in the 80's - so much of it smacks of being exactly the same today... you sure get the feeling that not a lot has changed since the NSA's founding in the 50's. (convincing telegram companies to turn over all correspondence to them... etc.)

[Gerald · Rating 5 out of 5]

Long before the current scandals, The Puzzle Palace presented an insider's view of electronic eavesdropping capability. One can only imagine how far technology has developed since then. More

[Steven · Rating 2 out of 5]

Well, didn't realize this book was written in the early 1980s so had nothing recent in it. I guess you can't judge a book by the cover. Interesting for a while, but honestly, way too dense and detailed with dates ranges of all administrators and key leaders, then not interesting.

Very informative......but boring as hell.

Readers born prior to 1980 may not have the same appreciation for this comprehensive review of the origins of the National Security Agency (NSA) and the operations (sometime unlawful operations) it has conducted. Many of the names will be unfamiliar to younger readers, who, let's say, do not present with the vintage age I do. But that shouldn't detract from the importance of what Bramford has to say and the agency's history and definitely should not stop the younger readers from reading this.

NSA was created and continues to exist without enabling Congressional authorization. It can and does spy on the signals everyone emits, including American citizens when thought to present a national security concern or when communicating with a foreign person or entity. Its operations are so secret that NSA officials rarely if ever are called to testify before Congress. Most is done in camera.

Bramford had access to information that he likely should not have had access to and, if I were to bet, I'd take the side of the bet that said the NSA and other security agencies did all they possibly could to prevent the publication of the book, which is very hard to find, although my first attempt to read the book in late 2025 was scuppered when I left the paperback version I had on an airplane or in the San Diego air terminal.

Bramford relates incidents going as far back as pre-WWII which he describes in detail. One incident held my attention that might suggest to some that the government of Israel is not a reliable ally. The incident involves the destruction by Israeli jets of an NSA vessel monitoring signals in the Suez region, and then the cover-up by Israel and lying at the US government, first, that it did not engage with the Liberty (name of the vessel) and then that the destruction where numerous US citizens were killed was based on faulty intelligence. These defenses were confirmed to be lies and hastily covered up by Israel and US counterparts. There are numerous other incidents related by Bramford that I'm sure NSA, CIA, and Congressional leaders did not want revealed.

This book is very detailed and can be tedious reading at times. But it is authoritative and recognized to be authoritative, and therefore, well worth reading even if the reader does not recognize the names or historic incidents involved.

Global communications have been monitored throughout the history of the world as civilizations try to gain information from neighboring peoples then share it in turn with other people they encounter. With the advancement of technology, the ways to obtain information have become more advanced and easy to get. The ideas acquired from others can help advance the civilization or ultimately to keep the threat of competition at a minimal. The Puzzle Palace by James Bamford is basically a novel about the National Security Agency (NSA), the most secret intelligence organization in America. The National Security Agency is an organization whose sole purpose is to decode and get hold of information and secrets held by other countries.

The highly secret organization was founded on April 24, 1930 in response to events during the First World War. It was originally named the Signal Intelligence Service and had a variety of other names since it was founded. The location of the facility has also been moved frequently and is vastly guarded by fences and barbed wire. It has set up a little community of its own names SIGINT City in Maryland and is one of the world’s most valuable communications and intelligence agency in quite possibly the world. It also seems to be a network unto its own ranging from going beyond the law to developing worldwide infringement on other countries to the total control over the people that work in the agency.

Codebreaking and gathering information from other countries could in fact carve out an identity for the country that is trying to obtain the information. For example, the United States is one of the leading nations trying to use the technology they have to gather information on other countries; this in turn provides a profile on that country. From assembling a nation’s information the country begins to take on a shape of its own; an identity that can shape the way the political structure of the country is or how the country runs certain aspects of its government. There is also a certain amount of influence a country has by having the information of another nation’s secret policies and strategies.

The country that is able to obtain all of another’s information essentially has a great deal of power over that other country. The United States has recently made it a point, with the creation of the National Security Agency, to try to get as much information on other countries as possible. One advantage to this is that if the United States learns secrets other countries are trying to hide, the United States has leverage with which to protect it’s own interests. For example, when the United States was bartering with Japan and were able to translate what they were saying because they knew the code for the Japanese transmissions. The United States therefore knew that the Japanese would be able to be brought down for less than the original bargain. As seen in the novel Blowback by Chalmers Johnson, the United States used the Joint Combined Exchange Training Program as a means of acquiring other countries training strategies and a map of the territory while covering it up to look like the United States was trying to help the country mobilize its own forces and make them better. Another advantage is that the United States is able to gather new information from other countries and use that to make further developments within it’s own nation. The ideas of others by creating new technologies and improvements in the way society functions can all be borrowed from other countries. In a reverse way that was detrimental to the United States, the Soviet Union was able to obtain the resources of how to make nuclear explosives. Secret communications is not always beneficial to the country that is getting them as with the new threat of nuclear war hanging over the world.

Global communications between allied countries are also established. Even though the United States is monitoring the communication of its allied nations, those nations can work together to gather information on third world countries or countries they are in conflict with. This is also beneficial because the nations do not have to overlap on obtaining information and can combine their individual resources to the utmost advantage. For instance, the United States placed monitoring stations in other countries such as Hong Kong in China, Britain, and Korea. This also helped to establish good foreign relations with other countries and contributed to the spread of information and technology.

With the advancement of technology, there were also ways to make gathering information from other countries easier. One advantage was to establish listening posts in other countries to monitor the activity going on. Having posts in other countries that the United States had good foreign relations with enabled information to pass more quickly to the agency and helped them to get more information than they could have otherwise. It would also be easier to get the codes that other countries have already broken, “Although the science of codebreaking has undergone tremendous changes in the years between the pencil and the CRAY-1 computer, one principle has remained constant: it is always far easier to steal a code-and much less costly-than to attempt to break it” (336). During the Second World War, Britain was able to steal secrets codes from the Germans, which made the allied nations able to read Germany’s details on advancing projects, military movements, and future plans. Obtaining the German’s cipher machine, the Enigma, was a major break through in the war.

The United States was also able to patrol the coasts by boat and pick up information using a radar system. The Valdez, a United States transport, patrolled around the coast of Africa eavesdropping on the coast territories and mainly monitoring the landing of Russian missiles that were being fired and keeping an eye on the newly emerging nations of Africa after they had been colonized by various European countries for many years. In later years, the United States and Russia even competed for the satellite revolution, the latest resource in espionage. Now countries began to take advantage of space as a means of intercepting the communications of others.

The United States intelligence agency while contributing in the global communications also gained power in the information it obtained from other countries. The secret organization of the National Security Agency maintains codes and information for the United States government and the governments of other agencies.

James Bamford’s The Puzzle Palace should be required reading for anyone trying to understand how the modern intelligence world actually came into being.

This book does an exceptional job of placing the reader inside the mindset of the Cold War, not just as a historical era, but as a psychological environment. Bamford shows how secrecy, signal intelligence, bureaucracy, fear, and technological ambition fused together at the height of the U.S.–Soviet standoff, creating systems and institutions that still shape our world today. What makes it especially compelling is that it doesn’t feel dated.

Many of the structural patterns described here feel uncomfortably familiar in the present.

As someone who has been asked a lot of questions about Cold War intelligence, classified programs, and the roots of modern surveillance while discussing my own novel The Umbra Signal, I keep coming back to this book as a grounding reference.

It explains where things were, why they evolved the way they did, and quietly hints at where they may be headed next. The reality is often more complex, stranger, and more human than fiction.

Bamford writes with clarity and restraint, letting documented facts do the heavy lifting. There’s no sensationalism here, just careful reporting and an understanding that the most consequential decisions are often made far from public view.

If you’re interested in Cold War history, intelligence agencies, signal analysis, or the unseen architecture behind global power, this book delivers real insight. And if you enjoy fiction that explores those same themes, this is an excellent window into the very real world that inspired them.

Highly recommended.

A little dated. Written before the end of the Cold War. The oldest computers are the high end IBM mainframe of the early 1970s and a Cray-1. One of them had the code name Lodestar or Lodestone (I read it long ago).

Slightly more up to date is Bamford's Body of Secrets: Anatomy of the Ultra-Secret National Security Agency from the Cold War Through the Dawn of a New Century which was more accurate pre-9/11 (which is another problem).

Palace is best read with David Kahn's The Codebreakers (even if David's book is somewhat dated), which includes photos Jim lacks.

I have since attended meetings and book events with both authors. Visit the Natl. Cryptologic Museum (NCM) on a weekday for a couple of hours if in the DC area. Closed Sundays and the library is closed on the weekend (Saturday). Very nice gift shop all factors considering (the NSA has better tee-shirts than the CIA).

"The Puzzle Palace" probably would have been a five star book back when it was published in 1982, a book that might have rattled a few cages and opened many eyes to what was then a secret organization.

Since then, not only has the world of spydom changed (or at least I hope it has!!!), but nonfiction narratives have changed as well. This book is crammed with specifics but it reads like a textbook, which is about the way most nonfiction was written forty years ago. These days we expect and appreciate an easier reading experience--one that blends interesting narrative with otherwise dry facts.

Because it's dated, and dry, I wouldn't recommend this book to casual readers. If you're intrigued by the ins and outs of intelligence gathering and distribution, this book will provide some insight into how it's been done in the past. And when taken in this way, the book helped me understand how faulty our intelligence systems have been and how good they've been--at the same time.

But the book is probably going to be of most value to those interested in the history of secret agencies, the National Security Agency (NSA) in particular. Who ran the agency when, what types of intelligence they were gathering, how they distributed secret information across vast distances, which scandals most rocked the NSA's world, and how the agency became less secret are all covered.

This is the original edition (1982 plus Afterword from 1983) of the definitive story of the National Security Agency. The author released a revised edition in 2001 which I haven't read. Considering how deeply the NSA had its hooks into everything in the 1960s, 1970s, and 1980s -- the reforms of the Church Committee notwithstanding -- it pretty much goes without saying that today the situation could only be much, much worse than as described in 1982. Now, EVERYTHING goes into the NSA's huge facility in Utah -- the Intelligence Community Comprehensive National Cybersecurity Initiative Data Center. Maybe -- maybe -- they can't yet decrypt everything, but they damn sure can grab it. So be careful what you say, write, post, blog, cast, email, text, etc.

[Thomas Busby · Rating 4 out of 5]

As a meticulously researched historical document, this is second to none in terms of its subject matter. 5*

As an entertaining and engaging read, it necessarily sometimes devolves into little more than a list of names and job titles. I don't resent it for this, but I'd be less than honest if I didn't admit that these sections were a little dry and tedious to push through. I understand why the author was keen to ensure that as much of the information he uncovered made it into this records as possible.

It's also worth noting that this book is quite old now. If you're looking to this book for information about the modern surveillance state leviathan, you won't find it.

All in all, I wholeheartedly recommend.

[Robert Liu · Rating 3 out of 5]

The final two chapters are essential: Competition (NSA vs the fledgling commercial/academic cryptography communities) and Abyss (NSA domestic surveillance outpacing the law).

Much of the rest is skippable, probably outdated. Do you want to read the NSA's org charts circa 1981? Outdated but still worthwhile are the chapters on satellite and microwave surveillance. It's almost certain that this still continues though the technology in the book is generations old.

Final impressions: I believe this book was written at the Cold War height of the NSA, when it had technological and cryptologic advantages over the Warsaw Pact and legal and secrecy advantages over the rest of civil society. I wonder how many of those advantages remain.

This came to me one evening under the radar. I couldn't sleep and needed something to read so I picked this up and read it in one sitting. So much for sleeping. It's a fascinating piece of work. Surprising in its reach and depth, and well written. I visited NSA (Columbia Annex) once for work and was immediately attracted to the environment. Truly a Puzzle Palace, both in my own experience and as told through the book. I have a funny story about the visit that I had forgotten. Perhaps I will write about it. Great book!

[Bill Allen · Rating 3 out of 5]

The title of this book reflects the struggle in reading it. There were some parts of the book that were entertaining and easy to follow, but there were many, many parts which were very difficult to plod through. The constantly changing organizational structure was bizarre and hard to follow, as were the seemingly constant personnel changes. Keeping up with them were like working through a puzzle maze to keep them straight - perhaps apropos of the book name. The last chapter was the easiest to read and brought everything to a fitting close, I think ....

[Martti · Rating 3 out of 5]

It is amazing this book was published at all, during the Cold War. Unfortunately it's very dry with lots of detailed information on the "anatomy" of the organization, but the second half returns into storytelling mode giving an impressive account of history about some international and domestic incidents. Bamford's book has been a reference material on many later books dealing with crypto. Like, well, Steven Levy's "Crypto".

[Lino Patti · Rating 3 out of 5]

The book is worth the read because its eye-opening to what goes on in the intelligence organization; however, to get through the book you must read through over 100 pages of an extremely dry and boring history account of the NSA and who was in charge. The book will tell an exhilarating story but then go through a chapter that is not at all interesting. It was hard to be motivated to pick up the book and finish or continue. The book would be a lot more enjoyable if they cut out half of the book.

[Sheri · Rating 3 out of 5]

This book released in the '80s. Much of it was quite interesting. But for me there were too many names. The research the author did was exhaustive and complete. But it stops so many years ago. Many of the details are no longer interesting or important. My significant other loves this book; he would give it 5 stars. For me, while much of it was interesting, much of it was also boring. I just wasn't the reader for this.

Thoroughly researched and sourced, this is an authoritative treatment of the NSA. I used to think this agency was a class act. Now I understand that it’s always been a criminal organization with no regard for the rule of law. The behavior revealed in the Snowden leaks is not new. I am glad I turned down their offer when I was finishing school.

An other dated But great book on the NSA. It had lots of details you'd wonder how/why a NYT's author would have on a super secret spying organization who reports to nobody with no oversight! Oh well, I look forward to reading this author's newer books on the NSA! Anyone who hasn't read this and thinks they Know how much the US Government is spying on US and the world, is mistaken!
