She penetrates the dead woman's world and dresses like her and goes to the nightclubs where she went and interviews her family and friends as she digs up the dirt. The character and personality of the dead woman haunt the narrative. Her fascination with this crime victim is the engine that drives the story. The dead woman's presence is riveting.
This is not your typical hard-boiled mystery, thank heaven. It reads like a mainstream or even literary novel and comes closer to "The Secret History" that to the genre stuff of Robert B. Parker. It swept me up in its world. As a writer myself, I had very few nitpicks, which is unusual. I recommend it highly.
