This volume of 4 Detectives brings together four early female detectives who use their formidable skills in crime-solving to track down and capture criminals of every variety. Madelyn Mack and her journalist pal Nora are particularly good at involved puzzles. Violet Strange helps others as an undercover detective while she makes enough money to solve a problem of her own. Miss Van Snoop has one very important criminal to catch, in the only short story she is featured in, while Florence Cusack and her friend Dr. Lonsdale star in five short stories. It's not just female intuition or feminine wiles that brings criminals to justice in these stories; there is plenty of good old-fashioned detective work.
