When FBI agent John O Hara first meets Nora Sinclair, she seems perfect. She has the career. The charisma. The tantalising sex appeal. The whole extraordinary package - Nora doesn t attract men, she enthrals them. She s worked hard for this life and she will never give it up. But why is the FBI so interested in Miss Sinclair? Mysterious things keep happening to the men in her life. And when Agent O Hara looks more closely he sees something dangerous in Nora - something that lures him at the same time as it fills him with fear. And the more time he spends with her the less he knows whether he is pursuing justice or his own fatal obsession.
