Seattle police detective Lou Boldt and police psychologist Daphne Matthews return in No Witnesses to confront the most challenging case of their careers. People are dying throughout Seattle ― victims of a madman who is placing poisoned food in neighborhood supermarkets. But the criminal is intelligent: he writes the police chilling extortion letters ― faxed directly from a laptop computer over public telephone lines ― and retrieves his ransom electronically, through automatic teller machines in hundreds of locations around the city. And while he is a murderer, his crimes take place miles and often days away from his innocent victims' demise. How can you stop a criminal when there is no crime scene to study ― and no witnesses? Daphne knows that no killings take place in a vacuum: there must be psychological motivations that she should be able to determine if she digs deep enough.
