In this episode Jessica Fletcher gets a blast from the distant past, her high school days to be precise. Leslie Nielsen is back in town and he was a charmer then and hasn't lost a step. She was serious about Nielsen then, but apparently chose wisely in marrying the late Frank Fletcher.
In fact it's William Windom who hears about his career in some shady dealings that's alert first. Nielsen has a crew of young divers looking in the harbor for buried treasure. Nielsen also has loan shark Sean McClory on his case as well.
There's a near fatal accident to one of the divers that looks suspicious. Then one of the young women on the dive is killed on a road and it's made to look like a hit and run, rather clumsily.
Angela Lansbury is a shrewd woman, I couldn't quite buy what she does as far as Nielsen is concerned. It also turns out the deceased was killed for what I consider trivial reasons.
Not one of the better stories.
