Sorry I didn't get back to this.
Ian Malcolm dies in the end of Jurassic Park.
He writes it as a faked death in the lost world and to me it screams of deus ex machina.
If he'd have meant it to be a fake death in Jurassic Park, he'd have bothered writing it. All it says is something to the effect of "The burial of Ian Malcolm wasn't even allowed".
Universal wanted a sequel to the movie and he started writing the books accordingly.
Really a brilliant author, but a filthy whore.
