Lou Diamond is known for being the best field agent around in the Los Angeles Police Department's elite division, the Office of Special Services. The OSS, quite simply, gets the worst crime jobs on the planet-and Lou Diamond, at one time or another, has seen them all. An ex-tactical assault agent with Special Weapons and Tactics, Diamond has enjoyed a near one hundred percent success rate in solving any crime, anywhere.

But when lawyers suddenly end up mysteriously dying at his brother's prestigious law firm, the evidence to be found is wanting in every way. The suspects in Lou Diamond's book are all dirty in some way, but all clear of the suspicion of murder. As the body count continues to grow at the firm he is investigating, so to does Diamond's belief that the murderer at large is killing with a purpose other than personal revenge.

Things become more complicated still when he meets one of the firm's most powerful partners, the beautiful and alluring, Linda Baylor. Compelled into a bizarre, sexual relationship with Baylor, Diamond begins to have a terrible suspicion that there is a gray area between sex, trust and blood. And that at the end of the day, nothing is as it seems-and no one is who they claim to be.

Lou Diamond comes to understand that the end result of such ambiguity is death.
