An easy reading book, but some bizarre subplots which detract from the main plot. Clear he's setting up for a 4th book.
In the previous book, there was a fanatical jihadi doctor - in this book, his story is reduced to getting killed in a car chase, after randomly getting in the midst of the teams surveillance on a main character.
Bizarre inclusion that became no more than a page's worth of story, but had been set up to be bigger in the previous book.
All round an odd book.
