Scarecrow and Mrs. King

Scarecrow and Mrs. King (1983-1987) is a Cold War-era spy show about a divorced housewife who, through a chance meeting, ends up working for a secret government agency. The series is built around the growing romantic relationship between secret agent Lee Stetson, a.k.a. Scarecrow (Bruce Boxleitner) and Amanda King (Kate Jackson) as they fall in love and eventually get secretly married.

As of 2011, the first two seasons have been released on DVD.

Tropes used in Scarecrow and Mrs. King include:

Almost Kiss
Amicable Exes: Amanda and Joe King, for the most part.
Badass Unintentional: Amanda King
Beware the Nice Ones: Amanda is very nice. Until she is provoked into being less so.
- She can clomp people over the head with a piece of furniture and then shrug her shoulders and smile ever-so-demurely as if to say that she really wants to get back into the kitchen, but right now of course she has to maim enemy agents, alas.
City of Spies: Set in 1980s Washington, D.C., which was very much a real-life example of this.
The Cuckoolander Was Right: Amanda has a tendency to go off on long and spectacularly irrelevant-sounding rambles which have the other characters staring bemusedly (and which usually end with her coming up with a clue that solves the case).
Code Name: Scarecrow. The series eventually revealed that Lee's codename was part of a The Wizard of Oz-themed set which also included Dorothy and Tin Man.
Cold War: Late 80's, Pilot Episode had KGB agents stealing a package.
Crouching Moron, Hidden Badass: Amanda
Deadpan Snarker: Francine
Front Organisation
Good Old Fisticuffs: Apparently trained agents use these.
Hot Mama: Amanda (and she has the t-shirt to prove it)
I Have My Ways: From the episode "The First Time":

Amanda: How did you find me?
Lee: We have our ways.

Improvised Weapon: Amanda often comes up with one.
Knight in Sour Armor: Scarecrow
Lighter and Softer: You would not realize this as the same genre John Le Carre or even Ian Fleming wrote in. Heck, Touched By an Angel is often Darker and Edgier than this.
Mistaken for Badass: Amanda is one of the best examples. While not mistaken for it as such she slips into the spy game accidentally.
- In one episode, she is even mistaken for Scarecrow by the Russians.
Opposite Gender Protagonists: It's right there in the title.
Parental Obliviousness: Amanda's mother Dotty takes this to new levels
Ruritania: There are two episodes in Germany and one in Austria that play upon this.
Secret Relationship: How the series maintains the tension after They Do
Spy Couple: The titular couple.
Spy Fiction
Will They or Won't They?: Once a romantic attraction started manifesting between the two, this became an element of the plots. Eventually they did, and even got married.
