The 70's seemed to be awash with Supernatural drama's/ TV plays like this. Such a great thing we can access almost all of them now-albeit in not so good quality on YTbe.
This story is effective- the tension does build, and though most viewers will think of at least one obvious way the thrill at the end could have been heightened...it is well worth the wait.
The only thing I can think of that is remotely like this now, in terms of quality and "single story" macabre is the truly excellent "Inside No.9" (With added humour).
