Meet the Author

Dan Brown

Dan Brown is the author of numerous #1 bestselling novels, including Digital Fortress, Angels & Demons and The Da Vinci Code, which has sold more than 80 million copies worldwide, making it one of the best selling novels of all time. Named one of the World's 100 Most Influential People by TIME Magazine, he has appeared in the pages of Newsweek, Forbes, People, GQ, The New Yorker, and others. His novels are published in 51 languages around the world. He is a graduate of Amherst College and Phillips Exeter Academy, where he also taught English. Digital Fortress was inspired by his experiences at the academy. He lives in New England with his wife.


Novelist Dan Brown may not have invented the literary thriller, but his groundbreaking tour de force The Da Vinci Code -- with its irresistible mix of religion, history, art, and science -- is the gold standard for a flourishing genre.

Born in Exeter, New Hampshire in 1964, Brown attended Phillips Exeter Academy (where his father taught), and graduated from Amherst with a double major in Spanish and English. After college he supported himself through teaching and enjoyed moderate success as a musician and songwriter.

Brown credits Sidney Sheldon with jump-starting his literary career. Up until 1994, his reading tastes were focused sharply on the classics. Then, on vacation in Tahiti, he stumbled on a paperback copy of Sheldon's novel The Doomsday Conspiracy. By the time he finished the book, he had decided he could do as well. There and then, he determined to try his hand at writing. His first attempt was a pseudonymously written self-help book for women co-written with his future wife Blythe Newlon. Then, in 1998, he published his first novel, Digital Fortress -- followed in swift succession by Angels and Demons and Deception Point. None the three achieved commercial success.

Then, in 2003, Brown hit the jackpot with his fourth novel, a compulsively readable thriller about a Harvard symbologist named Robert Langdon who stumbles on an ancient conspiracy in the wake of a shocking murder in the Louvre. Combining elements from art, science, and religion, The Da Vinci Code became the biggest bestseller in publishing history, inspiring a big-budget movie adaptation and fueling interest in the author's back list. In 2009, Brown continued Robert Langdon's esoteric adventures with The Lost Symbol, a tale of intrigue that, like its predecessors, takes readers on a wild ride into the sinister mysteries of the past.

Good To Know

  • Brown revealed the inspiration for his labyrinthine thriller during a writer's address in Concord, New Hampshire. "I was studying art history at the University of Seville (in Spain), and one morning our professor started class in a most unusual way. He showed us a slide of Da Vinci's famous painting "The Last Supper"... I had seen the painting many times, yet somehow I had never seen the strange anomalies that the professor began pointing out: a hand clutching a dagger, a disciple making a threatening gesture across the neck of another... and much to my surprise, a very obvious omission, the apparent absence on the table of the cup of Christ... The one physical object that in many ways defines that moment in history, Leonardo Da Vinci chose to omit." According to Brown, this reintroduction to an ancient masterpiece was merely "the tip of the ice burg." What followed was an in-depth explanation of clues apparent in Da Vinci's painting and his association with the Priory of Sion that set Brown on a path toward bringing The Da Vinci Code into existence.

  • If only all writers could enjoy this kind of success: in early 2004, all four of Brown's novels were on the New York Times Bestseller List in a single week!

    In our interview with Brown, he shared some of his writing rituals:

    "If I'm not at my desk by 4:00 a.m., I feel like I'm missing my most productive hours. In addition to starting early, I keep an antique hourglass on my desk and every hour break briefly to do push-ups, sit-ups, and some quick stretches. I find this helps keep the blood -- and ideas -- flowing.

    "I'm also a big fan of gravity boots. Hanging upside down seems to help me solve plot challenges by shifting my entire perspective."

    Chapter One

    They were in the Smoky Mountains at their favorite bed-and-breakfast. David was smiling down at her. "What do you say, gorgeous? Marry me?"

    Looking up from their canopy bed, she knew he was the one. Forever. As she stared into his deep-green eyes, somewhere in the distance a deafening bell began to ring. It was pulling him away. She reached for him, but her arms clutched empty air.

    It was the sound of the phone that fully awoke Susan Fletcher from her dream. She gasped, sat up in bed, and fumbled for the receiver. "Hello?"

    "Susan, it's David. Did I wake you?"

    She smiled, rolling over in bed. "I was just dreaming of you. Come over and play."

    He laughed. "It's still dark out."

    "Mmm" She moaned sensuously. "Then definitely come over and play. We can sleep in before we head north."

    David let out a frustrated sigh. "That's why I'm calling. It's about our trip. I've got to postpone."

    Susan was suddenly wide awake. "What!"

    "I'm sorry. I've got to leave town. I'll be back by tomorrow. We can head up first thing in the morning. We'll still have two days."

    "But I made reservations," Susan said, hurt. "I got our old room at Stone Manor."

    "I know, but-"

    "Tonight was supposed to be special-to celebrate six months. You do remember we're engaged, don't you?"

    "Susan" He sighed. "I really can't go into it now, they've got a car waiting. I'll call you from the plane and explain everything."

    "Plane?" she repeated. "What's going on? Why would the university ...?"

    "It's not the university. I'll phone and explain later. I've really got to go; they're calling for me. I'll be in touch. I promise."

    "David!" she cried. "What's-"

    But it was too late. David had hung up.

    Susan Fletcher lay awake for hours waiting for him to call back. The phone never rang.

    Later that afternoon Susan sat dejected in the tub. She submerged herself in the soapy water and tried to forget Stone Manor and the Smoky Mountains. Where could he be? she wondered. Why hasn't he called?

    Gradually the water around her went from hot to lukewarm and finally to cold. She was about to get out when her cordless phone buzzed to life. Susan bolted upright, sloshing water on the floor as she grappled for the receiver she'd left on the sink.


    "It's Strathmore," the voice replied.

    Susan slumped. "Oh" She was unable to hide her disappointment. "Good afternoon, Commander."

    "Hoping for a younger man?" The voice chuckled.

    "No, sir," Susan said, embarrassed. "It's not how it-"

    "Sure it is" He laughed. "David Becker's a good man. Don't ever lose him."

    "Thank you, sir."

    The commander's voice turned suddenly stern. "Susan, I'm calling because I need you in here. Pronto."

    She tried to focus. "It's Saturday, sir. We don't usually-"

    "I know" he said calmly. "It's an emergency."

    Susan sat up. Emergency? She had never heard the word cross Commander Strathmore's lips. An emergency? In Crypto? She couldn't imagine. "Y-yes, sir." She paused. "I'll be there as soon as I can."

    "Make it sooner." Strathmore hung up.

    Susan Fletcher stood wrapped in a towel and dripped on the neatly folded clothes she'd set out the night before-hiking shorts, a sweater for the cool mountain evenings, and the new lingerie she'd bought for the nights. Depressed, she went to her closet for a clean blouse and skirt. An emergency? In Crypto?

    As she went downstairs, Susan wondered how the day could get much worse.

    She was about to find out.

    Chapter Two

    Thirty thousand feet above a dead-calm ocean, David Becker stared miserably from the Learjet 60's small, oval window. He'd been told the phone on board was out of order, and he'd never had a chance to call Susan.

    "What am I doing here?" he grumbled to himself. But the answer was simple-there were men to whom you just didn't say no.

    "Mr. Becker," the loudspeaker crackled. "We'll be arriving in half an hour."

    Becker nodded gloomily to the invisible voice. Wonderful. He pulled the shade and tried to sleep. But he could only think of her.

    Chapter Three

    Susan's Volvo sedan rolled to a stop in the shadow of the ten-foot-high, barbed Cyclone fence. A young guard placed his hand on the roof.

    "ID, please"

    Susan obliged and settled in for the usual half-minute wait. The officer ran her card through a computerized scanner. Finally he looked up. "Thank you, Ms. Fletcher." He gave an imperceptible sign, and the gate swung open.

    Half a mile ahead Susan repeated the entire procedure at an equally imposing electrified fence. Come on, guys ... I've only been through here a million times.

    As she approached the final checkpoint, a stocky sentry with two attack dogs and a machine gun glanced down at her license plate and waved her through. She followed Canine Road for another 250 yards and pulled into Employee Lot C. Unbelievable, she thought. Twenty-six thousand employees and a twelve-billion-dollar budget; you'd think they could make it through the weekend without me. Susan gunned the car into her reserved spot and killed the engine.

    After crossing the landscaped terrace and entering the main building, she cleared two more internal checkpoints and finally arrived at the windowless tunnel that led to the new wing. A voice-scan booth blocked her entry.


    The armed guard looked up. "Afternoon, Ms. Fletcher."

    Susan smiled tiredly. "Hi, John."

    "Didn't expect you today."

    "Yeah, me neither." She leaned toward the parabolic microphone. "Susan Fletcher," she stated clearly. The computer instantly confirmed the frequency concentrations in her voice, and the gate clicked open. She stepped through.

    The guard admired Susan as she began her walk down the cement causeway. He noticed that her strong hazel eyes seemed distant today, but her cheeks had a flushed freshness, and her shoulder-length, auburn hair looked newly blown dry. Trailing her was the faint scent of Johnson's Baby Powder. His eyes fell the length of her slender torso-to her white blouse with the bra barely visible beneath, to her knee-length khaki skirt, and finally to her legs ... Susan Fletcher's legs.

    Hard to imagine they support a 170 IQ, he mused to himself.

    He stared after her a long time. Finally he shook his head as she disappeared in the distance.

    As Susan reached the end of the tunnel, a circular, vaultlike door blocked her way. The enormous letters read: CRYPTO.

    Sighing, she placed her hand inside the recessed cipher box and entered her five-digit PIN. Seconds later the twelve-ton slab of steel began to revolve. She tried to focus, but her thoughts reeled back to him.

    David Becker. The only man she'd ever loved. The youngest full professor at Georgetown University and a brilliant foreign-language specialist, he was practically a celebrity in the world of academia. Born with an eidetic memory and a love of languages, he'd mastered six Asian dialects as well as Spanish, French, and Italian. His university lectures on etymology and linguistics were standing-room-only, and he invariably stayed late to answer a barrage of questions. He spoke with authority and enthusiasm, apparently oblivious to the adoring gazes of his star-struck coeds.

    Becker was dark-a rugged, youthful thirty-five with sharp green eyes and a wit to match. His strong jaw and taut features reminded Susan of carved marble. Over six feet tall, Becker moved across a squash court faster than any of his colleagues could comprehend. After soundly beating his opponent, he would cool off by dousing his head in a drinking fountain and soaking his tuft of thick, black hair. Then, still dripping, he'd treat his opponent to a fruit shake and a bagel.

    As with all young professors, David's university salary was modest. From time to time, when he needed to renew his squash club membership or restring his old Dunlop with gut, he earned extra money by doing translating work for government agencies in and around Washington. It was on one of those jobs that he'd met Susan.

    It was a crisp morning during fall break when Becker returned from a morning jog to his three-room faculty apartment to find his answering machine blinking. He downed a quart of orange juice as he listened to the playback. The message was like many he received-a government agency requesting his translating services for a few hours later that morning. The only strange thing was that Becker had never heard of the organization.

    "They're called the National Security Agency," Becker said, calling a few of his colleagues for background.

    The reply was always the same. "You mean the National Security Council?"

    Becker checked the message. "No. They said Agency. The NSA."

    "Never heard of 'em"

    Becker checked the GAO Directory, and it showed no listing either. Puzzled, Becker called one of his old squash buddies, an ex-political analyst turned research clerk at the Library of Congress. David was shocked by his friend's explanation.

    Apparently, not only did the NSA exist, but it was considered one of the most influential government organizations in the world. It had been gathering global electronic intelligence data and protecting U.S. classified information for over half a century. Only 3 percent of Americans were even aware it existed.

    "NSA" his buddy joked, "stands for 'No Such Agency.'"

    With a mixture of apprehension and curiosity, Becker accepted the mysterious agency's offer. He drove the thirty-seven miles to their eighty-six-acre headquarters hidden discreetly in the wooded hills of Fort Meade, Maryland. After passing through endless security checks and being issued a six-hour, holographic guest pass, he was escorted to a plush research facility where he was told he would spend the afternoon providing "blind support" to the Cryptography Division-an elite group of mathematical brainiacs known as the code-breakers.

    For the first hour, the cryptographers seemed unaware Becker was even there. They hovered around an enormous table and spoke a language Becker had never heard. They spoke of stream ciphers, self-decimated generators, knapsack variants, zero knowledge protocols, unicity points. Becker observed, lost. They scrawled symbols on graph paper, pored over computer printouts, and continuously referred to the jumble of text on the overhead projector.

    Eventually one of them explained what Becker had already surmised. The scrambled text was a code-a "cipher-text"-groups of numbers and letters representing encrypted words. The cryptographers' job was to study the code and extract from it the original message, or "cleartext." The NSA had called Becker because they suspected the original message was written in Mandarin Chinese; he was to translate the symbols as the cryptographers decrypted them.

    For two hours, Becker interpreted an endless stream of Mandarin symbols. But each time he gave them a translation, the cryptographers shook their heads in despair. Apparently the code was not making sense. Eager to help, Becker pointed out that all the characters they'd shown him had a common trait-they were also part of the Kanji language. Instantly the bustle in the room fell silent. The man in charge, a lanky chain-smoker named Morante, turned to Becker in disbelief.

    "You mean these symbols have multiple meanings?"

    Becker nodded. He explained that Kanji was a Japanese writing system based on modified Chinese characters. He'd been giving Mandarin translations because that's what they'd asked for.

    "Jesus Christ." Morante coughed. "Let's try the Kanji."

    Like magic, everything fell into place.

    The cryptographers were duly impressed, but nonetheless, they still made Becker work on the characters out of sequence. "It's for your own safety" Morante said. "This way, you won't know what you're translating."

    Becker laughed. Then he noticed nobody else was laughing.

    When the code finally broke, Becker had no idea what dark secrets he'd helped reveal, but one thing was for certain-the NSA took code-breaking seriously; the check in Becker's pocket was more than an entire month's university salary.

    On his way back out through the series of security checkpoints in the main corridor, Becker's exit was blocked by a guard hanging up a phone. "Mr. Becker, wait here, please."

    "What's the problem?" Becker had not expected the meeting to take so long, and he was running late for his standing Saturday afternoon squash match.

    The guard shrugged. "Head of Crypto wants a word. She's on her way out now."

    "She?" Becker laughed. He had yet to see a female inside the NSA.

    "Is that a problem for you?" a woman's voice asked from behind him.

    Becker turned and immediately felt himself flush. He eyed the ID card on the woman's blouse. The head of the NSA's Cryptography Division was not only a woman, but an attractive woman at that.

    "No" Becker fumbled. "I just ..."

    "Susan Fletcher." The woman smiled, holding out her slender hand.

    Becker took it. "David Becker."

    "Congratulations, Mr. Becker. I hear you did a fine job today. Might I chat with you about it?"

    Becker hesitated. "Actually, I'm in a bit of a rush at the moment." He hoped spurning the world's most powerful intelligence agency wasn't a foolish act, but his squash match started in forty-five minutes, and he had a reputation to uphold: David Becker was never late for squash ... class maybe, but never squash.

    "I'll be brief." Susan Fletcher smiled. "Right this way, please."

    Ten minutes later, Becker was in the NSA's commissary enjoying a popover and cranberry juice with the NSA's lovely head cryptographer, Susan Fletcher. It quickly became evident to David that the thirty-eight-year-old's high-ranking position at the NSA was no fluke-she was one of the brightest women he had ever met. As they discussed codes and code-breaking, Becker found himself struggling to keep up-a new and exciting experience for him.

    An hour later, after Becker had obviously missed his squash match and Susan had blatantly ignored three pages on the intercom, both of them had to laugh. There they were, two highly analytical minds, presumably immune to irrational infatuations-but somehow, while they sat there discussing linguistic morphology and pseudo-random number generators, they felt like a couple of teenagers-everything was fireworks.

    Susan never did get around to the real reason she'd wanted to speak to David Becker-to offer him a trial post in their Asiatic Cryptography Division.

      I bought this book after reading the da Vinci Code. It was the last one I read and by now his formula for writing books was not working.

      I bought this book after reading the da Vinci Code. It was the last one I read and by now his formula for writing books was not working.

      Regardless, the ultimate downfall of this book is BAD WRITING. The characters are flat and annoying. Their actions are contradictory to their personalities -- for no other purpose than to move the 'plot' along. I think Dan Brown has a Word-a-Day calendar and he uses that new vocabulary word several times in the 10-15 pages of writing he produces that day. Words such as 'andalusian' are used several times in a 3 'chapter' span and then never again surface throughout the book.

      Most frustratingly, Dan Brown apparently never learned similes are functional and get the point across, but should not be used often as they can be extremely annoying and counterproductive to getting a point across. Towards the end of the book all these sentences are seriously used in less than 2 full pages:
      - "The commander rose through the trap door LIKE Lazarus back from the dead."
      - "Freon was flowing downward through the smoldering TRANSLTR LIKE oxygenated blood."
      - "Susan was standing before him, damp and tousled, in his blazer. She looked LIKE a freshman coed who'd been caught in the rain. He felt LIKE the senior who'd lent her his varsity sweater." [nice double simile, huh?]
      - "Her gaze was LIKE ice -- the softness was gone. Susan Fletcher stood rigid LIKE an immovable statue." [another one] "The puddle of blood beneath Hale's body had spread across the carpet LIKE an oil spill."

      Believe it or not, there are more in this 2 page space, but I'll stop here. Yes, the writing is THAT groan-inducingly bad. These two classics in the book make me laugh every time I think of them -- "Like in a cheap hollywood movie, the lights went out in the bathroom just as she heard the scream," and "any more interesting than last night and I'll never walk again."

      Ultimately, I did finish the book. BUT I WAS DISAPPOINTED.

      Exciting, but weak on accuracy.

      I read Dan Brown's "Deception Point" and enjoyed it, so I went on to "Digital Fortress." Unfortunately, this novel cured me of Dan Brown. It's full of cliff hanging high intensity excitement, but is so totally unbelievable that I could not really enjoy it. He apparently did not research anything about computer programming and has taken great liberties with the facts about computer hardware operations.

      Sorry I bought this book

      My first negative book review: so very disappointed in this book. In fact, I could not finish it - I was unwilling to invest any more time to find out what happened. It was that badly written.

      Written early in Brown's career (ar at least earlier than Angles and Demons and The Davinci Code), Digital Fortress was not at all what I hoped or expected.

      Character development - who thinks the way these characters do? Plot development - formulaic and unlikely at the same time. Technical accuracy - couldn't say, except that Brown dives overly-deep into code-breaking programming, a common mistake when an author researches something technical and wants to share everything he or she has learned.

      While I've never felt Brown is the best writer, he usually tells a compelling story. This one should have remained in his head.

      Not an Engaging Read

      Just awful. The book lost credibility with me fast. It involves a contemporary consultant to the CIA who is supposed to not ever heard of the National Security Agency. I've heard of the NSA--as someone casually interested in public policy--decades ago. A very well-researched book on the agency, The Puzzle Palace was published in the 80s. There is a note at the front of the Digital Fortress claiming Brown consulted with anonymous sources in the agency for his novel. If Brown actually had, you'd think they might have told him right off that his hero would have to be a dolt never to have heard of the NSA, and so certainly wouldn't be consulted by the CIA. A minor thing? Perhaps. But coming so early in a not-very-well-written book, it killed it for me and I found it hard to read much further. I'm not a big fan of The DaVinci Code--I thought the writing clunky, the plot predictable, the history execrable. But it had at least the virtue of a provocative and ambitious premise. This doesn't.

      Make another great movie

      I really enjoy the works of Dan Brown and this book has not been a let down. As expected, he has captured the readers attention from the beginning and holds it until the end.

      Loved it!

      Everything he writes I thoroughly enjoy! I would however say Angels & Demons was his best. I highly recommend this book as well as all his others & look forward to anything he publishes!

      I thought that this book was so-so. The book just never quite drew me in. I thought that Deception Point was a better book.

      Not worth your time

      Brown attempts to use the same format that was so successful in 'Angels and Demons' and 'The Da Vinci Code' but falls short. The plot is weak, the characters are underdeveloped, and it is a chore to even finish this book. I do not recommend this book to anyone.

      What a horrid book!

      Reading this book was like watching a train wreck. The only reason I finished reading it was to confirm the ending I guessed at the mid-point of the novel. I almost called the publisher after finishing to demand my money back. The technical errors are glaring. If you're going to write a book like this, take five minutes to speak with a cryptologist and another five with a sysadmin to get your facts straight. What a disappointment.

      Not one of Dan Brown's better books

      I really can't recommend this book, unless you are really into computers, & can write programs. It seemed repetitive, & not as riveting as his other books.

      I enjoyed this relatively early writing effort that seems to follow a formula of characters.

      We begin with the Heroine, Susan, dreaming about a planned weekend with her fiancé, David. They are in their middle years, she is a cryptologist and he a Professor of language. The weekend is delayed because he is asked to pickup the personal effects of a deceased programmer. The tale spins around a person that has been in the game too long, the Commander. He hatches a plot to preserve his glory and remove his perceived rival of Susan. The end is a destruction of a huge code breaking system, and several people including the plotter, his henchman, and several innocent people dyeing. The story reflects a common Dan Brown theme of someone seeking glory or preservation of cherished belief ending in a expensive tragedy with an emerging heroine getting her hero. It is not as well written as "The Da Vinci Code", but it shows improving literary skill.

      Decent tech thriller!

      A high tech thriller from the mid 90s shouldn’t hold up well nearly two decades later but Dan Brown’s Digital Fortress does pretty well. The book is bogged down by tech speak at times and other times that speak seems redundant in this day and age when everyone’s grandmother knows what Wi-Fi is. The characters are interesting but clichéd. There are some decent twists and a high intrigue level. Overall, this was a god book that I’m sure I would have enjoyed more had I read it in 1995.

      You start to read the book and you can not put it down highly recommended.

      Dan Brown is a excellent writer for people who like ,romance,mystery, suspense and adventure I would recommend it for all adult readers. I have read all of his books and have not been disappointed.

      Great story of the computer world

      Wow!! Great story but doesn't Brown always put together a great story. The plot is a little similar to his Robert Langdon stories, but yet is different in many ways. While the Langdon stories about about history and symbolic meanings, this story is about code breakers. Well researched, alot of suspense and on the edge of your seat, bitting your nails. Excellent read.

      Good but not his best.

      Having read Angels and Demons and The Da Vinci Code, both by Dan Brown, I thought I should try Digital Fortress also by him. I had high hopes for this book when I began to read it and I immediately saw the trademark Dan Brown layout. The surplus of short chapters makes his books especially this one an easy fast read but it didn't have the substance that his other books have. Digital Fortress is hardly a thriller; instead it is an apparent mystery that even the most oblivious person could figure out. The twists and turns are hardly perfected and could have been improved on immensely. Also the book hindered greatly from being mainly set in the NSA crypto lab, the setting was limited and it was hard for any growth of the characters. But the better parts of the book were the ones set in Spain with David Becker, these parts kept me interested in the book. With an assassination plot, car chases, and a few funny parts the parts of the book with Becker kept my interest and made it easier to get through the book. Another problem with Digital Fortress is that there is a lack of cryptograms and puzzles. Had Dan Brown added some more puzzles in the book for us readers to figure out, I personally would have been more involved with the book and would have enjoyed it a lot more. If you are looking for a great thriller you won't find it here, instead read Dan Brown's other books, Angels and Demons and The Da Vinci Code. He has perfected upon his writing style and plot twists. If you like reading his books then Digital Fortress is still a quick decent read but it will have you wanting more.

      Fantastic read

      After reading Digital Fortress, I had a new understanding of and appreciation for the writing style of Dan Brown. I couldn't put it down. His gripping style of writing lead me to page after page of action; I couldn't anticipate what was going to happen next. It was faced-paced, and brought out the best and worst of his characters' personalities. He is a master of putting it all together. I highly recommend this book for those who are interested in computers and science fiction. The description of the actions seems to float off the page as if you were literally there.
