For decades, the unsolved murder of Father Michael Leary has haunted Billings, Montana, the community he served. Who summoned the priest late one autumn night, then left his body in a sandstone gully for the ravens and other wild scavengers?

And it’s haunted no one more than Lindsay Keller, who admired and confided in him as a teenager. Compelled by his example to work for justice, she became a prosecutor. But after a devastating case left her shattered, she fled the rough-and-tumble for the safety of a desk, handling real-estate deals and historic preservation projects. It's good work, but not what she’d dreamed of.

Now Lindsay finds herself in possession of the priest’s wallet, the photo of a young girl tucked inside. She’s sure that she knows the girl and that it’s tied to his death. But how?

Detective Brian Donovan, a hot-shot Boston transplant, would like nothing more than to solve the county’s coldest case. Probing the life and death of Father Leary takes Lindsay and Donovan deep into long-simmering tensions in this seemingly peaceful place.

Then another woman far away digs up unexpected clues about her own family’s past—a history rooted in a shocking truth—and her questions bring her to Lindsay and the detective. But the dangerous answers could rock the community to its very core.
