FBI Agent Alex Cross is on vacation with his family in Disneyland when he gets a call from the Director. A well-known actress was shot outside her home in Beverly Hills. Shortly afterward, an editor for the Los Angeles Times receives an e-mail describing the murder in vivid details. Alex quickly learns that this is not an isolated incident. The killer, known as Mary Smith, has done this before and plans to kill again.
Right from the beginning, this case is like nothing Alex has ever been confronted with before. Is this the plan of an obsessed fan or a spurned actor, or is it part of something much more frightening? Now members of Hollywood's A-list fear they're next on Mary's list, and the case grows by blockbuster proportions as the LAPD and FBI scramble to find a pattern before Mary can send one more chilling update.
