I despise spy novels. Ok, maybe that was too strong. I definitely didn't like this one. There was no meat to chew on for me. I met with one other member of the Thriller Book Club who had similar thoughts and I figure others didn't join in because they didn't like it (or couldn't get through it) either.
I couldn't attach myself to any of the characters either; none of them had an appealing backstory. Maybe Maurice, but his part was minor.
If that is the spy life - I'm glad I'm not part of it.
I also couldn't capture any "psychological elements" that were super apparent. Maybe the idea of multiple personalities, but these spies entered these double lives willingly, so it's not really a psychosis. There were elements of dual relationships (i.e., daughter investigating father), but also not salacious enough.
So, this is the shortest blog, but I'm willing to discuss if you have any further input ...
