Hundreds of feet below Manhattan, a treacherous tunnel maze is inhabited by the sandhogs, teams of workers who are rebuilding New York City's deteriorating water supply system. Their dark and dangerous world turns deadly when a catastrophic explosion rips through Water Tunnel #3, sending shock waves that are felt throughout the city and inside the courtroom where Alexandra Cooper is dead-set on nailing young businessman Brendan Quillian for the murder of his wealthy wife. The blast sends Alex's case in a shattering new direction -- and pulls her and detectives Mike Chapman and Mercer Wallace underground to dig up ancient rivalries and homicidal secrets that may pull Alex in too deep.... Brimming with Linda Fairstein's trademark blend of brilliant detective work, cutting edge forensics, and electrifying legal drama, Bad Blood melds two distinctive and riveting New York domains with seamless authenticity and nerve-jangling suspense.
