Private investigator Adam Knight, played by John Turner, promoted his services in the newspaper with a dramatic flair: Knight Errant ’59 offers to take on quests, vanquish metaphorical dragons, and rescue those in distress. Our services are available to anyone, anywhere, as long as they contribute positively. Fees are based on your ability to pay. Fashioning himself as a 20th Century Sir Lancelot, Knight set up the Knight Errant agency as a consultancy focused on assisting anyone with any issue.
