Private Investigator Derek Strange and his partner, Terry Quinn, are running a detective business in the seedy underbelly of Washington, DC when they are approached by a young man asking them to find his girlfriend who has gone missing. And so Strange and Quinn find her. Just another day? Not quite. In the grimy underworld inhabited by Strange, nothing is that simple. For Strange and Quinns efforts have led to a young mother being brutally murdered -- a devastating discovery that causes them both to question the morality by which they live. And yet at the same time they need to continue the search for another missing girl, a teenage runaway who shows up in a porn video. And who hasnt been seen since. Step by step, Strange and his partner are drawn into the darkness, confronting gunrunners, crime lords, drug dealers, and ordinary people caught up in the ruthless violence of the business.
