It takes a while until Hauser recognizes the MO of Webb Porter, who drowns women in their bathtubs at home and auditions as violinist. He suffered from tinnitus since his mother tried to drown him as a young child. Dr. Lucy turned the frightened mental wreck into a self-confident musician. Dr. Milton Beauregard tells Hauser how Webb may save Lucy’s life if caught in time, Doc and Madsen help track him down.
