The Witch of Agnesi Full-time math teacher and part-time troublemaker Bonnie Pinkwater cares about her students, so when thirteen-year-old math genius Peyton Newlin disappears, she’s compelled to investigate. One by one, students who were competing with the young genius turn up dead. Bonnie suspects Peyton—until he himself is murdered. The investigation leads Bonnie to a coven of witches, a teenage comic book magnate, a skinhead, an abusive father, an amorous science teacher, and a mistranslated medieval mathematics manuscript. As the body count mounts, Bonnie realizes the crosshairs are on her. A Calculated Demise Sadistic wrestling coach Luther Devereaux is found murdered, and Bonnie’s mentally challenged aide, Matt, is found with blood on his hands. Bonnie investigates a growing trail of blood until Superintendent Xavier Divine demands she cease her investigation or lose her job. But when the murderer nabs her dog, there’s no turning back. Irrational Numbers Leo Quinn came out of the closet five years ago. Now he’s found tied to a barbed-wire fence and shot through the heart on a backstretch of Colorado dirt road. Bonnie Pinkwater is drawn into the investigation when her phone number is found in Leo’s pocket. Bonnie and Principal Lloyd Whittaker start turning over rocks, discovering the target range of Leo’s father, a survivalist and former Marine. Next on the list is Leo’s former fiancée. Also in the mix is Harold T. Dobbs, the intolerant, homosexual-baiting pastor of the Saved by the Blood Pentecostal Tabernacle. And don’t forget Moses Witherspoon and Dwight Furby, empty-headed bigots who were out joyriding the day Leo was murdered.
