Home invasion - the kind of call every homicide cop dreads. Cincinnati detective Sonora Blair is called to a small house at the end of a cul-de-sac, and finds the brutal decimation of an average American family - deeply in dept. A high-profile search brings two ex-convicts, both murdered in prison within twenty-four hours of their apprehension. Evidence points to a third man at the murder scene - a man called the Angel, a man who runs a collection agency that can turn a debt into you worst possible nightmare.
