Inspector Dorothea LaSalle is nearing sixty - and the end of a long, unremarkable career in the police force. Or so she believes.

Balancing the care of a mother slipping into dementia and a husband growing increasingly distant, Dorothea is blindsided when her orderly life descends into chaos: a whirlwind of murder, drugs, corruption, and kidnapping. And to make matters worse—her own boss thinks she's at the centre of it all.

With her reputation in ruins and time running out, Dorothea turns to the only allies she has left: her idealistic rookie stepson and a loyal Detective Constable. Together, they must work off the books, navigating a criminal world where the players know the system better than she ever did.

Now, Dorothea must outrun the very law she spent her life upholding and expose a conspiracy that could destroy everything - before it destroys her first.
