The Chilson library bookmobile has a new stop on its route: Honey Hollow Adult Foster Care. When Minnie learns that Honey Hollow is just down the road from an enclave of gorgeous Victorian homes, she decides she has to take a look, especially after she learns about identical houses that stood side by side, and were owned by twin siblings. But when Minnie and Eddie and the bookmobile take their scenic detour, Eddie uncharacteristically escapes from the bookmobile - and finds a woman in the woods, horribly wounded with an arrow.

Though Minnie desperately calls 9-1-1, all too soon she realizes she was too late. The police seem ready to call the death a hunting accident, but Minnie can't shake the feeling that foul play was involved, particularly given the woman's final whispered words. With evidence lacking, Minnie and Eddie will have to claw their way through a thicket of suspects to find the truth.
