This one continues the adventures of four couples in a Florida Over-55 RV park and, as advertised in the title, there are two crime threads. First, Ron & Julie are asked to see if they can pin down which man living at the park might be the guy who murdered two people back in 1967. While they're working on that, rumors circulate that someone's peeping in trailer windows at night.
Of course there are humorous interactions between characters: husbands and wives, neighbor to neighbor, and senior citizens against the world. Shopping for lingerie, getting a confused old man to his doctor's appointment, and dealing with a guy who believes aliens run the government are everyday occurrences for the residents of the Beautiful Bird Over 55 RV Park.
