Killer Instinct by Nicola Williams

When the Senior Clerk at her Chambers is found dead in an alley, Lee Mitchell doesn’t know who she can trust.

Junior Clerk Dean is pinned for the crime. Working-class and still living on the estate where he grew up, he has the most to gain from Tom’s death. But Lee knows how easily prejudices can snowball into convictions – and steps in to defend him.

As her Chambers crumble into a world of chaos and deceit, and long-buried secrets come to light, Lee must question how well she really knows those closest to her, and who would kill to keep their past hidden . . .
