This is book 8 of the "Stone Barrington" series.

This note contains spoilers for the book.

Stone gets a weird job, pushed off on him by Woodman & Weld. As he investigates, he discovers that most of the things he's been told are lies, and he's somehow involved in intelligence work.

He's in England, but Dino is there too. Lance Cabot, who I have previously seen as a high CIA official, is operating freelance and working against British interests. I wonder how much detail we see about how he ends up inside the CIA?
