Book excerpt: Seven Bones is the story of one of the more bizarre murder investigations in Australia’s criminal history. Two wives die in suspicious circumstances: co-incidence or, as husband Thomas Keir describes it, ‘bad luck’? Arriving on the scene, Detective Peter Seymour realised he was dealing with the world’s unluckiest husband or a serial wife killer. Keir’s ‘grieving husband’ act was suddenly in question. The investigation revealed Thomas Keir was a man so jealous he hated even his own baby son touching his wife. A man who thought he could commit the perfect crime and publically taunted the police. Written through the eyes of Detective Peter Seymour, Seven Bones follows his relentless pursuit of justice through the drama that would take fifteen years to reach its final conclusion.
