Carol Starkey is a bomb squad veteran now doing time as a Detective-2 with LAPD's Criminal Conspiracy Section. Three years have passed since the detonation that killed Carol's partner and lover, but she is still severely scarred both mentally and physically. She can't bear to look in the mirror, and she hasn't been with another man since David Boudreaux left her bed that last morning he went to work. She gets through the day with the help of Tagamet and alcohol.
When a bomb call takes the life of another colleague, Carol begins to investigate a series of explosions that seem to be designed to exterminate bomb technicians. She soon realizes that she's "the one that got away." With the help of an FBI agent whom she loathes professionally for interfering with her job but finds attractive anyway, Carol must track down one of the most frighteningly brilliant killers of the modern age.
