Loves Music, Loves to Dance

This was a dated story about people who wrote personal ads to find dates. It was interesting to read about this when now people use online dating sites or phone aps. Times have changed a lot but I don't mind slipping into the past for a while now and then. This story had my attention but like a lot of Mary's stories I figured things out before the end. There are a lot of questionable characters who could be the murderer or guilty of some crime or bad deed. The question is which one is guilty of the worst crime of all - Murder.
