When a highly successful barrister and their family are mysteriously killed in their London home, Detective Jake Tanner is unexpectedly called to the scene. Inexperienced and out of his depth - and away from his desk - Jake soon learns there are more layers to the murders than he first thought.
As he and his veteran colleague, Detective Ashley Rivers, delve deeper into the high-profile case, they are faced with another challenge: the eldest daughter of the barrister has gone missing. And if they want her back, there’s a fee to pay.
With time running out, Jake must use his varied knowledge of the law and human behaviour, and his vague understanding of the streets of London, to locate the killer and save the girl before the deadline, and her life, is up.
