The Avengers: S04 - 1966 - 6/10

First season after the departure of Cathy Gale (the formidable Honor Blackman).
This marks the beginning of the Emma Peel (Diana Rigg) era, but is likely NOT the Emma fans think of.
Peel is less intimidating than Gale, more kittenish, more deferential to Steed.
In most episodes, she requires manly rescuing.
Late, very late in the season, Rigg must have asserted herself, and by “The House That Jack Built”, Peel is the cool, calculating partner fans think of.

The series, however, is becoming campy, playful. Not silly, but clearly heading that way.
“A Sense Of History” makes an interesting example. Robin Hood, arrows, murders, yet a late chance to see vintage Steed, ruthless and a brawler.
