I've just this moment read the last line of Robert Harris' Ghost. Incredible. I may have to study this book. The narrative structure strikes me as perfect. Maybe I'll pick up a copy of James Bell's Plot and Structure and read the two together. That's a fancy way of saying Don't open the book unless you're prepared to stay up nights reading.
bonus: His portrait of a writer having a breakdown is worth the price of admission alone.
For me it was.
