So.... The Da Vinci Code
Well I've read The Da Vinci Code and it seems like a bog-standard airport novel thriller with the addition of a couple of days of library research and occasional reference to a Lonely Planet Europe guide or similar. Presumably it got a fair bit of promotion when it came out, but why it has developed into a phenomenon is utterly beyond me.
Posting may be non-existent for the next few days since Castle Towers shopping centre, in the far north-western suburbs of Sydney, despite having more opportunities for consumer frenzy than you would think possible, has only one public internet machine. I guess you are supposed to buy a computer instead.
