I had to stop this one halfway through because the wife's constant blubbering was irritating. It seems this was a common affect in 1970's radio drama. Or at least in this series. Women were usually depicted as very weak and hysterical throughout most of these dramas. I can't understand why it took so long for actors and directors to realize women don't get hysterical over every moment of every drama and they don't scream their heads off every time they see something mildly startling. It comes across as forced and I'm sure it did back then as well. As far as this being based on true events - there's nothing about it that rings true to me.
