LAPD Detective Margaret Nolan is struggling to move forward after the death of her brother in Afghanistan and taking a life in the line of duty. Her stoic parents offer little support – they refuse to address anything difficult, and she’s afraid their relationship is eroding beyond the point of recovery. The days off are the hardest, because they give Margaret time to think. A moment of weakness leads to cocktails with a colleague—an attraction she knows could be dangerous —at the luxurious Hotel Bel-Air bar. A stroll through the grounds leads to a grim discovery beneath the surface of Swan Lake: the body of a successful attorney who made his fortune in international trade. It initially appears to be death by misadventure, but the case is anything but straightforward. As a series of shocking revelations emerge, Nolan finds herself confronting a sinister cabal that just might destroy her and everyone she loves.
