PRE-ORDER NOW: 3 FEB 2026

Suspicions that a serial killer is terrorizing a pristine tourist spot draw a single mom and budding private investigator into a twisting and deepening mystery of secrets and murder.

Single mom and newly minted private investigator Prairie Nightingale has opened the doors of her Green Bay, Wisconsin, agency and is ready for work. She and her crew aren’t quite prepared for their first client, Bernie Dubicki, a notorious online journalist and not-altogether-reliable provocateur, who claims the idyllic vacation destination of nearby Door County is home to a serial killer.

She’s pinpointed four seemingly unrelated deaths that haven’t raised suspicions for anyone else. But when a college student vanishes, Bernie’s sizable retainer convinces Prairie to help connect the dots. And trusted, flirty FBI agent Foster Rosemare thinks Bernie might be onto something. Prairie never expected her first investigation to be so big, like Dateline big, but she does have an inquiring mind and a knack for seeing things no one else can.

In this case she’ll have to look deep, not only into the secrets of strangers, but into Door County’s woods, to solve a mystery decades in the making.
