Detective Sergeant Ash Rashid has a steady job and a healthy family. Three hundred days sober, he can see his happy ending forming on the horizon. Then patrol officers find the body. The victim has chemical burns on her arms, two broken legs and a deep gash on her throat.
Then three more bodies are found. Each victim testified in a murder trial 10 years ago, one that launched Ash's career. Each of them helped put a dangerous man in prison, and now each has paid the price. Now someone plans to make Ash pay, and she’s willing to kill everyone who stands in her way.
