I believe Wilson's frogette was wife number 2. She was a French embassy employee in one of the 3rd tier countries where he served or rambled through in Africa. He was still married to the frogette when he was tiddling Valerie and Valerie was telling Joe about her Agency affliation "during a heavy makeout session" (as per Joe's own memoirs).
Wilson Wife #1 is the mother of the senior Wilson twin children, Valerie the 3rd, the mother of the junior twin Wilson children.
With Wilson's ego, mouth and pretensions, he wouldn't make a good spy for anyone. He makes Maxwell Smart look discreet.
What is somewhat curious is the fact that Wilson does not seem to come from money nor do any of the Wilson spouses seem to have been well off but Joe has lived QUITE well for a double divorcee with 4 kids to support, on a foreign service salary/pension, and a make-believe company he started that is supposedly headquartered in a warehouse in DC. Something the press has no interest in investigating.
I never even realized he had a second wife until I read this piece today. It does raise troubling questions. I need to check the timelines on this perhaps it connects more dots.
