After the water supplies of three residential areas are poisoned, a mass-casualty investigation begins under the assumption that the attack may be terrorism. Psychologist David Joseph instead suspects that the killings are the work of an individual whose private obsessions and deteriorating mental state have produced a different kind of threat.

David works with law-enforcement agencies to reconstruct the offender’s motives and anticipate the next attack. With no obvious limit to the possible targets, the case becomes a race to turn psychological clues into a practical identification before the killer can contaminate another community.
