Overkill by Sherry Fowler Chancellor

 No one liked Drusilla Isaacs. She spent a lifetime alienating people, as if making the most enemies was a personal goal. Now she’s dead. Shot, stabbed, and her neck broken…and that’s what the coroner can tell from a first look. It’s up to Maggie Blaine—former friend and one-time victim of the odious Drusilla—and Maggie’s partner, Jacob Brown, to figure out who, out of a seemingly endless list of suspects, would carry out such heinous acts. Their choices are varied. From Drusilla’s husbands—the former and the current—to the women in her life—her secretary, the mother of her husband’s son, or the new wife of her ex-husband. There’s also another option. A serial killer who randomly appears to insert himself into the mix. A tale of murder, gems, drugs, illicit sex, and a cast of villains who all have one thing in common—their hatred of Drusilla Isaacs.
