I've started a watch of the anthology series. I know that CMM did this boxset a few years back. I can remember the series airing back in the 70s but I don't think I ever saw an episode.

Lady Killer is quite a fun little start to the series with the familiar set up enlivened by some twists exactly when the narrative needed them and a rare example of a sock-based murder.
File It Under Fear was one which favourably impressed me, also the one with Diana Dors as a sinister nurse....'Feed a cold, starve a fever...'
