@bsag I half think Gary Oldman, aside from being a fine actor, was cast to give the Jackson Lamb character a little bit of ... dimension? I'm reading the books out of order, only now starting the first. So far, halfway through the first book, I don't know much of anything about Lamb. And I don't understand why people don't hit him with a broom whenever he opens his mouth.
One thing about the books that may be just the ticket for serial TV is that nearly all scenes are short. I mean really short. It's great for keeping the reader on seat's edge.
