Without warning, a boy in the middle of a city intersection sends Detective Oscar Mariani's car careening into a busy sidewalk. The scene is bedlam as every person becomes visited by something no one else can see. We are all haunted. Usually, the apparition is someone known: a lost relative, a lover, an enemy. But not always. For Oscar Mariani, the only secret that matters is the unknown ghost who now shares his every waking moment . . . and why. The worldwide aftershock of what becomes known as "Gray Wednesday" is immediate and catastrophic, leaving governments barely functioning and economies devastated . . . but some things don't change. When Detective Mariani discovers the grisly remains of an anonymous murder victim in the city sewage system, his investigation will pit him against a corrupt police department and a murky cabal conspiring for power in the new world order.
