I liked this series. The one episode I remember best is "Concrete Captain," where the body of an old sailor is entombed in a block of concrete. He was killed by the grandfather of one of the characters in the story (I think it was a mercy killing) by having a harpoon chucked through his heart. The top of the harpoon still sticks out of the concrete. Then the ghost of the sailor comes back to haunt everyone.
I also liked the theme music. I actually recorded it off the TV one night with my first cassette recorder. I still have that tape.
When they changed it to "Circle of Fear," I thought it was a mistake. The theme music was dumb, too.
