Undercurrents — Ridley Pearson

Police Sgt. Lou Boldt heads a special task force within Seattle's homicide bureau. His job: find and stop the Cross Killer, a twisted, perverse serial murderer who has eluded police for six months and paralyzed the city. But when a body washes up on the shore of Puget Sound, Boldt thinks the killer has finally made a mistake. This body shows some of the work of the Cross Killer -- but a job badly botched. Did this woman die while trying to escape? Did she knowingly jump in the water to preserve a clue? And is she now desperately trying to tell Boldt something? With the help of the alluring Daphne Matthews, a police psychologist, Boldt must piece together the complex puzzle.
