Slovenian sleuth Milan Jacovich (Full Cleveland, Pepper Pike), in an attempt to wrest an old pal's son from drugs, again must call on a Cleveland don for help and, at the same time, avoid the ``Jamaican Connection,'' a bloodthirsty island gang that uses school kids as dope-runners. In the midst of saving Paulie, Milan uncovers crack houses owned by rich car-dealer/would-be power-maven Waco Morgan and his mistress, the dumb but luscious Barrie Tremont. Several lethal and near-lethal hits later, Milan concludes that Waco, the Jamaicans, and the don's boys are not the brains behind the drug-racket--and then, in a grisly confrontation in a warehouse storing the Thriller, an old Euclid beach roller-coaster ride, he eliminates (at least temporarily) Cleveland's drug-kingpin. The divorced, middle-aged Milan's best scenes are with his two sons, the most clichÇd with young Mary, his disenchanted lover. And if he seems a shade too written-to-formula, his food is still as mouthwatering as anything Lawrence Sanders has come up with.
