A woman lies dead in an Antwerp apartment; nearby, a suicide bomber detonates his device at a fashion show. In Ireland, Detective Emer Berry of the Criminal Assets Bureau finds rough diamonds in a raid on a small-time drug dealer, along with the deed to that luxury Antwerp flat. When she heads to Belgium to investigate, Emer is confronted by Chief Inspector Christian de Jong of the anti-terrorism squad. Reluctantly banding together, they begin to untangle an international conspiracy involving drugs, terrorism, and corrupt corporate and political leaders. Caught up in this web of greed is the dead woman's employer, heiress Bibi Melnick, and the Brannigans, a wealthy Irish business dynasty. Drawn into a battle of wits with the family, Emer, Christian, and the CAB team must follow the money to stop another terrorist attack before it's too late.
