Started this one on Sunday night - first in the Ngaire Blakes series.
From the Blurb:
Forty years ago Magdalene Lynton drowned in a slurry. She choked to death as her hands scrabbled for purchase on the smooth concrete walls. A farmhand discovered her bloated body three days later.
Or she didn't.
Paul Worthington just confessed to her murder.
Forty years ago Magdalene Lynton died in a dirty shed. He smothered her life along with her cries for help and tossed her defiled corpse into a river when he was done.
Or he didn't.
