It has been three months since the case involving Alistair Anderson. And in these three months, a mysterious organisation has been massacring law enforcement officers in several countries. However, Ava Bailey only finds out about this when she discovers that Alistair is linked to that organisation. She suspects that the organisation may be doing that to exact its revenge on her for killing Alistair, and her suspicions are confirmed when she is roped into the Evanescence Intelligence Service to become a spy to take down the organisation before it rains destruction down on Evanescence. Her mission seems easy enough - get into the organisation's Evanescence-based stronghold, kill the leader of the organisation, and get out alive. However, as Ava goes along with it, she discovers more about herself than she has ever had before, and most of the things are so horrible that she starts asking herself: Am I evil?

Ava Bailey has never been a great detective, causing her to fall victim to a colleagues taunts. She is the detective with the least number of cases solved, and because of that, everybody is wary of assigning her cases to work on. Finally, the sergeant closest to Ava has a case for her, but on that very same day she gets the case, the police commissioner himself shows up in her office, threatening to take away her badge if she does not solve the case. Surrounded by people who look down on her, with only two people - her best friend and the sergeant - to support her, Ava dives into the case, unaware that it is linked to something far bigger than she can ever fathom. And with every turn, the case gets even more dangerous...
