Vermilion Drift

Cork O'Connor takes a security consulting job at the Vermilion One Mine, an old iron works in northern Minnesota now under consideration as a nuclear waste repository. Deep underground, he finds a sealed chamber, and inside it six bodies.

Five have been there for decades — the victims of a 1964 disappearance the county has always called the Vanishings. The sixth is recent, and was killed with a Colt that belonged to Cork's father, the sheriff of Tamarack County at the time the first five went missing.

Vermilion Drift is the tenth Cork O'Connor novel. It is the book in which Cork investigates his own family, and the county's foundational silence about what happened underground.
