The Three Deaths of Magdalene Lynton (Detective Ngaire Blakes 1)

Magdalene Lynton died forty years ago: a vivacious teenager who fell victim to a grotesque, accidental drowning. The coroner's office issued a verdict of death by misadventure and filed her case. The farming commune she'd lived within, splintered apart. Her body was left behind in a small, private cemetery encircled by acres of fallow ground.
Until Paul Worthington confessed to her murder. Magdalene's case lands with Ngaire Blakes, a Maori detective recovering from a brutal stabbing. After fighting for the resources to investigate, Ngaire discovers that Paul's confession doesn't fit with the facts of Magdalene's death. The trouble is, neither does the original verdict.
Together with her partner, Deb, Ngaire digs deeper into the case to uncover inconsistencies, lies, and mortal danger.
