Travelling from England to Australia in the late nineteenth century, Abigail Sergeant and her brother, Bertrand, are looking forward to their new life.
Leaving behind the prejudices that would likely have seen Bertrand committed to an institution before he reached adulthood, Abigail hopes their new life will offer freedom and security.
But what awaits them on the shores of the Swan River dashes any prospects of a blissful life. A murder is committed and Abigail's family is thrown into turmoil. The evidence is damning. Only the guilty would be found standing over the body clutching the bloodied murder weapon. But something is not right. Police are convinced they have their killer. Abigail is certain they are wrong. As their one potential witness is missing, Abigail persuades the detective to allow time for a search. But that time is limited. Chasing across Western Australia with a reluctant Constable Dunning as her chaperone, Abigail is determined to uncover the truth. If only she had an inkling of what that may be. Through deception, kidnap, sabotage and arson, Abigail finds a resolve she didn't know she possessed. Her understanding of mechanical principles surprises everyone, as does her tenacity. She turns out to be a capable young woman. But is that enough to save an innocent from injustice?
