Angela Richman is a Death Investigator, working for the ME's department. She is called out by the police when a death happens as the result of murder, highway accident, or any unattended death.
I've never run across such a job. For a small town near St. Louis, MO, there is a Medical Examiner, an assistant ME, a CSI tech, the Death Investigator, and a Homicide Detective, all handling the scene and the body of recently deceased. In this story, three young women's bodies are found buried in a forest. Two have been there for a few years so Angela doesn't handle them. When she notifies the families of the deaths, she always goes with a detective or police officer. Then, because one of the homicide detectives is misogynistic, racist, and toady to the ultra-rich families in town, Angela tries to avoid working with him.
There's some love interest in this book between Angela, a widow, and a police officer, but the story primarily focuses on finding evidence that one of the ultra-rich was responsible for the death of several women. There are also side stories of other obvious and unexplained deaths.
The stories hold together fairly well.
