La Clave Da Vinci

Patricia Da Vinci's career is on a high when she is asked to be a guest speaker at the prestigious Seattle Homicide Conference. Her presentation involves the recent case of the prostitute serial killer Charlie Josephs, who himself was found murdered. Her re-examination of the case leads to the discovery of several discrepancies and uncovers some new clues in Joseph's death, clues that seem to implicate the police. Sioux, who is now a police informant for Kosmo, implicates Danny in the drug trade and Kosmo is forced to examine her feelings for him.
