This series gives readers a pretty good picture of what World War II was like for performers on Broadway from the point of view of a world weary actress turned amateur sleuth from necessity and curiosity. The mysteries are fun, suspenseful in part, and clean, with a few crude words, but not much more to mar the stories. The actress uses mobster cant, but she runs with mobsters, so I guess it's sort of realistic. The mobsters, in general, turn out to have "hearts of gold." There is some oblique hints at immorality, but considering the atmosphere the book uses as its setting, it's very innocent.
