[I've been

This is either the third or the fourth book in the Ty Hauck series of thrillers. I enjoyed this one as much or more than the previous ones. Lots of back and forth about what is really happening, a principled main character (though he does seem to sort of run through relationships which is maybe getting old) and a lot of intrigue without a lot of torture or other super unpleasantness, though there is a somewhat high body count.
