"Digital Fortress" by Dan Brown

This is the second book of Dan Brown’s that I’ve read (I read The Da Vinci Code first, not realising that it was the second book in a series). This story however is a stand-alone novel that concerns the American National Security Agency (NSA), and its cryptographic division who have a sophisticated computer program that can decode anything in a matter of minutes, until it comes across a code written by a former employee.

A high level cryptographer in the NSA is called in to solve the riddle of this new code when the agency is essentially held hostage by a code system that threatens to put put them out of business, and ensure 100% privacy to everyone in the world - something no security agency would want.

Unlike numerous thriller novels there isn’t tonnes of violence, with everybody armed to the teeth, etc. This novel is could easily be considered a classic as it requires the reader to think, and understand rather than just experience the visceral pleasure.

It is great to see the emergence of strong female characters in Brown's books, as the spy/thriller genre has been centred almost solely on males for decades. An excellent novel, looking forward to reading more of his work.

"Secret Language: Codes, Tricks, Spies, Thieves and Symbols" by Barry J. Blake

I have had this book in my collection for quite some time, but never got around to actually reading it. I suppose in an off-handed away this is one advantage to the COVID-19 pandemic as none of the library's here are open so I am forced to actually read books that I've been meaning to (in some cases for years).

As it turns out this book is absolutely wonderful and Mr. Blake goes into significant amounts of detail with lots of examples from various languages, cultures, and history. A brief introduction deals with why people want to be mysterious. He then goes on to talk about topics related to anagrams and cryptic crosswords which includes things like palindromes and acronyms which he gives numerous examples of.

His next topic is all about riddles. Riddles have been with us for centuries, and have appeared in many forms. He discusses things like the rebus, the charade (and how it has changed from it's inception, into the kids game people are familiar with today). And then goes on to give some riddles that the reader can try.

The next section is one that I found extremely fascinating and that was on codes and ciphers. He deals with the history from pre-Roman times up to the present and the use of computers. Once again he gives the reader some interesting challenges.

The next three chapters deal with biblical secrets, words of power, and words to avoid. These are explored from a historical as well as a cultural viewpoint. His next chapter deals with jargon, slang, argot and various secret languages.

He ends the book with a discussion of things like politeness, humour, euphemism, abusive language, oxymorons, parody and satire to name but a few.

I found this to be an excellent book, and was quite sorry that I hadn't read it many years ago. It is especially renewed my interest in codes and ciphers, and I'll be reviewing another book that I have on that in the future.
