[Cadillac Jack, a] rambling drifter of a man—an antiques spotter who travels the country searching for collectible treasures and who acts as a middleman between seller and dealer—can't quite find the key to his own life. What Jack does find is himself in love with two women, and he's unable or unwilling to choose between them. While the plot often seems to be going nowhere at half-speed, McMurtry injects some marvelously comic poignancy into Jack's purposeless meanderings and creates a number of memorable characters in the bargain. A natural for fans of the author's wistful brand of soul-searching.
