1st to die: [a novel]

From the publisher. Imagine a killer who thinks, "What is the worst thing anyone has ever done?" -- and then goes far beyond it. Now imagine four women -- a police detective, an assistant DA, a reporter, and a medical examiner -- who join forces as they sidestep their bosses to track down criminals. Known as the Women's Murder Club, they are pursuing a murderer whose twisted imagination has stunned an entire city. Their chief suspect is a socially prominent writer, but the men in charge won't touch him. On the trail of the most terrifying and unexpected killer ever, they discover a shocking surprise that turns everything about the case upside down.
