amazon.com says "A brutal madman sprays bullets into a crowd of children leaving a San Francisco church. Miraculously-or was it intentionally?-only one person dies. Then an elderly black woman is hung. Police homicide inspector Lindsay Boxer senses a connection and together with medical examiner Claire, assistant D. A. Jill, and Chronicle reporter Cindy, finds a link that sends a chill through the entire nation. This killer's motives are unspeakable."
