My life was ordinary until three years ago when I was thrown out of a downtown hotel window. My name is Robbie Brownlaw, and I am a homicide detective for the city of San Diego. I am twenty-nine years old.I now have synesthesia, a neurological condition where your senses get mixed up. Sometimes when people talk to me, I see their voices as colored shapes provoked by the emotions of the speakers, not by the words themselves. I have what amounts to a primitive lie detector. After three years, I don't pay a whole lot of attention to the colors and shapes of other people's feelings, unless they don't match up with their words.When Garrett Asplundh's body is found under a San Diego bridge, Robbie Brownlaw and his partner, McKenzie Cortez, are called on to the case. After the tragic death of his child and the dissolution of his marriage, Garrett--regarded as an honest, straight-arrow officer--left the SDPD to become an ethics investigator, looking into the activities of his former colleagues. At first his death, which takes place on the eve of a reconciliation with his ex, looks like suicide, but the clues Brownlaw and Cortez find just don't add up. With pressure mounting from the police and the city's politicians, Brownlaw fights to find the truth, all the while trying to hold on to his own crumbling marriage. Was Garrett's death an "execution" or a crime of passion, a personal vendetta or the final step in an elaborate cover-up?
