Mrs. Emma Peel(Diana Rigg).
John Steed's partner for
two seasons of The Avengers
from 1965-1968 (last episode 'The Forget-Me-Knot' aired 1/12/69). She drove a powder blue
Lotus Elan S2 convertable. Diana later
moved on to being the wife of 007 in
"On Her Majesty's Secret Service".
She dies at the end though.
My two favorite Avengers episodes are "Too Many Christmas Trees" and "The House That Jack Built".
