Dan Brown. Love him or hate him, you've got to admire the skill with which he's managed to write a clutch of successful novels which are practically bloody identical. Take some pathetically simple cryptography, one twist, a lemon - usually the lead character - and a bunch of two-page long chapters and voila, one Brown book. The best-seller of these templates, The Da Vinci Code, has spawned a film, a court case, and now the inevitable computer games, of which this isn't one. Well, it's obviously cashing in on the impending Hollywood blockbuster, but unlike Take-Two's official Da Vinci Code console license, this has absolutely nothing to do with murder in the Louvre.
