Georgia medical examiner Sara Linton returns in Slaughter's Grant County crime thriller series (Indelible ), and this time she's hot on the trail of a demented killer who buries teenage girls alive. Out in the woods chatting about past infidelities, Sara and ex-husband/lover Jeffrey discover a young girl buried in a grotesque coffin, dead despite a breathing pipe extending to the surface. The victim is soon identified as Abigail Bennett, a member of the Holy Grown soybean farming collective, a group curiously unfazed to learn a daughter was poisoned. Suspicion blooms around Holy Grown's many farmhands, mostly ex-felons on work release, but then centers on the parishioners who congregate at the Church for the Greater Good, a local congregation run by a shifty minister. Another shallow grave, physical violence and another girl's disappearance lead Sara, Jeffrey and assisting detective Lena Adams back to the Bible-thumpers and their unholy dealings. Issues of abortion, domestic abuse and forgiveness afford these recurring female characters three-dimensional humanity, nicely offsetting Slaughter's patented grim forensic detailing. Slaughter's fifth Grant County case offers tough love, suspenseful spadework and life-affirming vigor.
