Loved this show as kid.
A proper and dashing Edwardian gentleman crime fighter was frozen and then revived decades later in the swinging 60s. Part of the fun was how Adam would whip out his sword cane at opportune moments and do battle with bad guys. He also was quite visibly uncomfortable being around modern brazen women. BBC - Cult - Classic TV - Adam Adamant Lives!
This show now goes against our modern conception of upper class Edwardians having been depraved and useless at anything except grandiose self involvement. Kind of like how the dot commers were.
