Even a midlife crisis doesn''t stop PI Sharon McCone from getting involved in the case of the ''Diplo Bomber'', a terrorist who has maimed or killed half a dozen foreign diplomats. San Francisco homicide cop Adah Joslyn enlists McCone''s help when the bomber warns that his next target will be the San Francisco-based consulate of Azad, an oil-rich Arab emirate. But it''s not until McCone meets the engaging nine-year-old granddaughter of the Azad consul that she gets hooked. The case is as puzzling and frustrating as any she''s worked on, taking her from San Francisco''s seamy underworld to the sparkling beauty of a remote Caribbean island. And just when McCone thinks she''s finally figured out who the bomber is, even she''s surprised by one final, macabre twist.
