When a little girl is shot on the steps of a San Francisco church, Detective Lindsay Boxer reconvenes the Women's Murder Club. Working with reporter Cindy Thomas, assistant DA Jill Bernhardt, and medical examiner Claire Washburn, Lindsay tracks a mystifying killer who quickly turns his pursuers into victims. The unorthodox allegiances of the Women's Murder Club lead them to suspect the unexpected - the killer may be an ex-cop. But nothing prepares them for the demented logic behind his choice of victims.
