Put these two together (a lie-detector and an adrenaline-fuelled eye for detail), and you have a completely unfair toolkit for reading novels, simply because novels are very rarely actually "novel" - they're more often an assembly of ideas.
Take Scarlett Thomas' "PopCo" (FourthEstate, 2004), for example. Superficially, it's like a 500-page anagram of my life (BBC Micro / chess / maths / philosophy / Godel's Incompleteness Theorem / videogames / business / marketing / cryptography / cryptology / secret history / Voynich Manuscript / etc), together with a load of other untaken doors (Bletchley Park / SOE / crosswords / vegetarianism / vegan / Go / low-level drug-use / homeopathy / etc), and it's written quite well: so I really should be engaged by it, right?
Problem #1 is one of construction: the first tranche is basically Douglas Coupland (specifically Microserfs), the second tranche Iain Banks (his fiction rather than his science fiction), then a bit of Martin Gardner's puzzle columns and Simon Singh's The Code Book: there's a kind of teenage girls' magazine section along the way, and a rather clunky historical pirate romance, before it all flips out into Thomas' fictional take on Naomi Klein's No Logo... Yet to me, a book needs to be more than merely a collage of influences, a narrated scrapbook: but perhaps that makes me too old-fashioned for contemporary fiction. If you wanted to be kind, you might compare it with Kurt Schwitters' Merz, carefully arranged collections of found objects (forged Merz pieces get placed on eBay all the time): but sorry, Thomas is no Schwitters.
Problem #2 is the lack of parents. The other day, while watching (the original TV series of) Batman on BBC4, my four-year-old son asked me where Batman came from. Well, I said, a man called the Joker killed both Bruce Wayne's parents, and when a bat bit him in the caves beneath his mansion, he somehow gained a super crime-fighting ability. OK... so where did Spiderman come from? Well, I said, after both Peter Parker's parents died, he was bitten by a radioactive spider, and gained amazing spider-like powers. My son paused, looking back at the screen. But what about Robin, he asked. No, don't tell me, I know: both his parents were killed... Before he had a chance to say "(and he was bitten by a radioactive robin)", I suggested we look Robin up on Wikipedia (though sadly he was basically correct). In PopCo, the main character Alice Butler is basically Crypto Girl, a sort of Elonka-lite: her mother dies and her dad runs away, and she gains her m4d cryptological and prime factorisation sk1llz from her grandad. Put it that way, and it all looks a bit comic-book thin, doesn't it?
Problem #3 is that I'm wise to novelistic conceits. I know that in a cryptological novel, someone called A[lice] is going to communicate with someone called B[en], who will pass on what she says to someone called C[hloe]: and this kind of spoils it. Incidentally, Ron Rivest denies that he used "Alice" and "Bob" (in his 1978 paper introducing RSA public-key cryptography) in any kind of homage to the film "Bob & Carol & Ted & Alice" (which is actually a bit of a shame). It would also have been cool if PopCo's Alice had been born in 1978 and openly named in crypto homage to Ron Rivest's paper, but I think she's too old (is she 29? I can't find the page, rats!).
Problem #4: cringeworthy logic/maths puzzles. To give texture to her story, Thomas brings together loads of lateral puzzles and mathematical ain't-that-amazin' fragments, the kind of thing that you sometimes hear being trotted out at student parties. For example:-Two men go into a restaurant and order the same dish from the menu. After tasting his food, one of the men goes outside and immediately shoots himself. Why? (p.109) The explanation given for this in PopCo is ludicrous (it involves an albatross and a dead child, don't get me started): but why is one not simply a food-taster for the other? Fugu: mmm, delicious... hey, what's that trainee doing in the kitchen... aaaarrgggh!
Problem #5 (probably the biggest of all for a Voynichologist) is that PopCo uses the Voynich Manuscript as a MacGuffin (or do I mean a "Philosopher's Egg MacGuffin"?). Alice's grandfather spends years on the VMs, and even gets her to count the words and letters on each page (and later to factorise large numbers): perhaps washing his car would have been a better way to earn pocket money. Alice says that she's learnt so much from the journey, from the search for the heart of the VMs: but really the manuscript is no more than occasional wallpaper for the narrative. The Beale Papers also make a brief appearance: my guess is that Scarlett Thomas would have used them as the central hook, had there been more than a paltry $20million dollars' worth of treasure linked to them: the alternative "Stevenson/Heath" pirate cipher mystery Thomas constructs is a bit thin when held up against real ones, regardless of the size of its haul.
...and so on. I feel in a bad place: I really wanted to like PopCo, but all I can do is whinge (and I haven't even moaned about her merging Alberti's and Vigenere's cryptography, etc). Other reviewers (such as here and here) seem basically to like the book: and compared to Dan Brown's Digital Fortress (where I wanted to kill all the main characters by the end of Chapter One, all the minor characters by the end of Chapter Two, and the publishers by the end of Chapter Three) it's Shakespeare.
Cryp-lit like this requires a certain kind of technical devotion from the reader, and if you are a diehard crypto-geek PopCo is something you really ought to read. But only if you've read the good stuff (like Neal Stephenson's excellent Cryptonomicon) first.
