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.
