Bad Blood finds Assistant DA Alexandra Cooper deeply involved in a complicated, high-profile homicide case. Defendant Brendan Quillian, a prominent young businessman, is charged with the brutal strangulation of his beautiful young wife, Amanda. His conviction is not a certainty: Quillian was conveniently out of town on the day of the killing, and he has hired a formidable defense attorney who seems one step ahead of Cooper as the trial opens. But with the help of detectives Mike Chapman and Mercer Wallace, she is confident she can prove Quillian paid a hit man to commit the crime. Halfway through the trial, a major catastrophe alters the course of Alex's case. A cataclysmic ex-plosion rips through New York City's Water Tunnel #3, a spectacular feat of modern engineering that will be completed years in the future. Carved through bedrock six hundred feet underground, the tunnel will replace a vital artery in the city's rapidly deteriorating water supply system. Was the blast caused by terrorism? Political retribution? Or was it merely an accident? Cooper is quickly drawn into the trag-edy when she discovers a strange connection linking Brendan Quillian to the tunnel workers killed in the explosion.
