Based on the classic ITV series, The Avengers – Steed And Mrs Peel: The Comic Strip Adaptations Volume 1 collects four new stories adapted from the classic comic strips which appeared in Diana magazine between 1966 and 1967.

Ahead of its release later this month, we're pleased to unveil a short behind-the-scenes clip from series stars Julian Wadham and Olivia Poulet, who discuss stepping into the suits and shoes of Patrick McNee and Diana Rigg.

Available to pre-order today, this four-disc box-set contains four freshly adapted adventures for the iconic pair:

1. Return to Castle De'ath adapted by Simon Barnard and Paul Morris

Steed is left hanging, Emma pays the piper.

Steed and Peel return to the scene of an earlier adventure to find it much changed. Now a ski-resort, Castle De'ath is playing host to many new visitors - including a wealthy Prince targeted by assassins.

Assigned as bodyguards, the Avengers have to keep the Prince alive and discover which of the Castle's guests are behind the murderous plot - before they succumb to it themselves.

2. The Miser adapted by Simon Barnard and Paul Morris

Steed has a nasty scare, Emma has a pressing engagement.

When the phrase 'sleeper train' takes on a very literal meaning, Steed and Peel witness the first action of The Miser, a terrifying extortionist.

The race is on to stop his ambitious scheme - but in this case, appearances can be deceptive. 

3. The Golden Dresses adapted by Paul Magrs

Emma hits the heights of fashion, Steed plumbs the very depths.

The ladies of society can't get enough of Madame Zingara's Golden Dresses. Especially now their husbands have gone missing.

Steed and Peel look into the world of haute couture to discover the dark secret of this latest craze. Can they pull it off with style?

4. The Norse Code adapted by John Dorney

Steed has the horns of a dilemma, Emma milks her moment.

An agent has gone missing whilst holidaying in the Norfolk Broads. With an American nuclear bomb being stored in the region, Steed and Peel can't take any risks.

But the last thing they expect to find on their boating trip is a Norse longboat. What are Vikings doing in East Anglia?
