With little work during the pandemic, Chicago PI Georgia Davis agrees to help the best friend of fellow sleuth, Ellie Foreman. Susan Siler's aunt died suddenly after her Covid booster, and Susan's distraught mother wants the death investigated.
However, Georgia's investigation is interrupted by a family trip to Nauvoo, Illinois, the one-time Mormon heartland. It's there that her life unexpectedly intersects with the runaway spouse of a Mormon Fundamentalist.
Back in Evanston, after Georgia is almost killed by a hit and run driver, she discovers that she and the escaped woman look remarkably alike. Is someone trying to kill Georgia because of her death investigation? Or is it a case of mistaken identity? And how can Georgia find her doppelganger before whoever wants them both dead tries again?
