1900, Melbourne, Victoria.

Miss Prudence North is freshly returned from university in Scotland and determined to find her place among the male-dominated world of the new forensic sciences when a high-ranking policeman waylays her. He threatens to charge her father for illegal medical practices unless she helps him build a case against local landowner Jasper Darke by spying on him.

With her sister’s illness worsening, if their income disappears Prudence will have to take on nursing and domestic duties and she’ll never have the freedom she craves. Prudence has no choice but to agree.

Immediately taken with the handsome Mr Darke, a seemingly good and honest man, Prudence can’t see what nefarious activities she’s meant to be reporting on. She’ll have to get closer …

But when a body turns up at her father’s surgery, the forensics reveal to Prudence there’s more going on about all this than meets the eye. It’s clear it’s up to her to uncover the truth - of this murder, of whatever’s going on at the surgery after hours and, especially, of the intriguing Jasper Darke. Her life, her family and her future rely on it.
