“Knight Errant ’59. Quests undertaken, dragons defeated, damsels rescued. Anything, anywhere, for anyone, so long as it helps. Fees according to means.”

Adam Knight is a young man who, having tried several jobs, decides to set up an agency, ‘Knight Errant ’59’, to solve other people’s problems – whatever they may be. There’s plenty of scope and, assisted by former reporter Liz and idealistic young writer Peter, the latter-day Sir Lancelot is kept busy with a variety of curious and exciting cases.

John Turner starred in this memorable Granada series with, for the first two series, Canadian-born Kay Callard and Richard Carpenter (who later made the transition from actor to writer and is best known as the creator of Catweazle); in the series’ later incarnation, Knight Errant Limited, Hugh David filled the role of the benevolent trouble-shooter with Wendy Williams as his secretary.

Although 75 episodes were made, only two still exist; this set presents these remaining two episodes from Knight Errant ’59 and Knight Errant Limited.
