Andrew Pitman is an agent with the CIA.
He is rapidly approaching retirement and is looking forward to it.
So is his wife, Alexis, though she is planning to retire from Russian Intelligence. Of course it might be also that she was really working for the Agency but that is not established so far so I do not know. What I do know is that these two are very much in love and have no secrets from each other.
I also am aware of the fact that while Andrew is a very intelligent and inciteful agent, one who has risen to the position of Deputy Director for Foreign Operations, a job he thinks of as the "foreign office", the real logical thinking in the family is Alexis. This woman sees everything, grasps the subtlety in everything, and has the brainpower to put the pieces together in such a way as to be spooky. It is no wonder Andrew loved her so much.
