Lies are poison . . . but so is the truth

Professor Eustacia Rose has been arrested. Her charge: possession of poisonous plants without the appropriate licence. But behind the scenes, ulterior motives are at play...

 Locked in a windowless cell, Eustacia begins to uncover memories she didn't know she had. Her father's work on a mysterious academic paper. The night he was arrested, accused of murder. And a woman with long black hair that Eustacia does not recognise.

 Linking all the memories is Marcus Smith, her father's unscrupulous assistant, a man she thought was long dead. Marcus ruined her father's career, stole his research and vanished after a heated confrontation. But the past never stays buried, as Eustacia knows all too well.

 With the help of DCI Roberts and determined allies, Eustacia races against time to expose the deceptions of the past and solve a fresh murder before it's too late. This is her only chance to clear her father's name and settle a decades-old score, but the truth can be a bitter pill to swallow...
