I recently came across this tv series on Youtube. I am just too young to have watched it as a kid although I remember it being on. I think my parents probably thought that I was too young to understand the subtleties of the characters and situations. They were probably correct as the series seemed to cover most of the deadly sins somewhere within the 26 episodes. For the 1960's it was an astonishingly realistic and gritty production.
John Thaw is at his best in his first starring role, and it makes interesting viewing to see which of the many other, now famous, actors can be spotted in each episode.
Another curious and rare thing which makes watching Redcap worthwhile is that of the 26 episodes that were made, no less than 25 actors, other than Thaw, appear in 2 episodes. They can be spotted playing characters of completely different rank and class, sometimes as goodies, sometimes as baddies. It gave the actors a great opportunity to display the range of their acting ability.
