A murder with no weapon or motive. A detective on edge. A community that wants answers. Impurity is the first in a series of six books featuring Leeds based Detective Inspector Stewart Gardener. One fateful night, DI Stewart Gardener intervenes in a street brawl, and his wife is shot dead. Finding his wife’s murderer is never far from his mind, but with no leads and a hazy recollection of events, it seems hopeless. Soon he is presented with a shocking case. A man is found dead in a grubby apartment, and It is not long before another man meets the same fate.

DCI Kenny Murrain sees, hears and feels things that others do not. It’s a gift but also a curse. When he wakes to the phantom sound of screaming, he knows a murder has been committed, but not where or why. Then a woman’s body is found in a Stockport hotel room. It’s a murder that seems both frenzied and carefully planned, the scene expertly cleansed of any evidence.

Fresh out of uniform, DC Jimmy Bliss finds himself at the centre of an undercover sting. Enlisted by a crew of villains to crack a safe, he fears his cover is blown when he’s seen in the wrong place at the wrong time. But on the night of the job, things run smoothly enough until the gang leader changes the location of the heist. As the job spirals out of control, Bliss has to trust his instincts and buy some time. There’s just one problem: he has no idea if his team know what has become of him.

When DS Royston Chase is called to the scene of a fatal road collision, his task is to identify the girl who died alongside the ex-chief constable of Wiltshire Police. Paired with the bold and strident DC Claire Laney, Chase is given the task of closing the case quickly and quietly. But when the girl’s DNA provides a familial link to a child who vanished from her home 20 years earlier, Chase and Laney refuse to accept the coincidence. The pair start looking harder at the ex-cop’s life, at which point they encounter serious opposition. Perhaps deadly serious.

When Victoria Davies was pushed off her stately home's roof in 2001, all evidence pointed to her husband Michael.
