Series 4 of the much-loved spy-fi show The Avengers saw the introduction of Emma Peel, played by Diana Rigg, who teamed up with the gentleman spy John Steed (Patrick Macnee).

This was the last Avengers series to be filmed in black and white, and was one of the first British series to be shown on prime-time American television after being sold for $2 million!

The 7-disc box-set of The Avengers Series 4 is out on 5 July 2010. But Total Sci-Fi has a copy up for grabs. Just take a look at the following question:

Who played Cathy Gale in previous series of The Avengers?

a) Chops McGraw
b) Babs Eggpoach
c) Honor Blackman
