Too Many Crimes, Too Many Characters

Murder is Secondary (A Susan Wiles Schoolhouse Mystery) by Diane Weiner is one in a series of nine novels. The About the Author section notes this is a cozy mystery. I have never been sure what that is. In searching for a definition, I found that there is generally an almost absence of sex and violence but there is some sort of mystery that is supposed to appeal to intelligent women. Also, the mystery typically takes place in a community where everybody knows everybody. This sounds like the TV series Murder She Wrote. I hope no one minds if I occasionally spy on what intelligent women are reading.
