Silent Witness

by Mary Germano

A chilling novel that tells of a terrifying killer and the final target of his deadly scheme. Katherine Hansen has been with the computer company too long to stand by and watch it bow to sabotage. And as unexplained power failures, sinister phone calls, and other bizarre threats mount, it becomes clear that she is the last major obstacle in a campaign of terror.
