Innocent in Death by J.D. Robb

The phenomenal series set in a future New York City returns as NYPSD Lt. Eve Dallas hunts for the killer of a seemingly ordinary history teacher-and uncovers some extraordinary surprises. Craig Foster's death devastated his young wife, who'd sent him to work that day with a lovingly packed lunch. It shocked his colleagues at the private school, too, and as for the ten-year-old girls who found him in his classroom in a pool of bodily fluids-they may have been traumatized for life.
