Charter boat Captain Dusky MacMorgan is hired by the CIA to thwart an assassination attempt on an island near Boca Grande, Florida. Along the way he falls for a waitress named Marina, enrolls in a week-long fat farm on St. Caribe island, becomes the enemy of a Mediterranean instructor named Matrah, befriends fat farm client and movie star Sonya, and befriends German instructor Heinrich. Dusky finds himself the hunted as well as the hunter when the assassin leaves him a note. This is the last of 6 Dusky MacMorgan novels Randy Wayne White wrote before he started writing the Doc Ford series.
