In "Cadillac Jack, " Larry McMurtry -- Pulitzer Prize-winning author of Lonesome Dove -- proves his unique talent for conjuring up the real, often eccentric people who inhabit the American heartland and for capturing the peculiarly American search for new frontiers and adventure. "Cadillac Jack" is a rodeo-cowboy-turned-antique-scout whose nomadic, womanizing life -- centered on his classic pearl-colored Cadillac -- rambles between the Texas flatlands of flea markets and small-time auctions and Washington, D.C.'s political-social life of parties, hustlers, vixens, and spies. Along the way he meets a cast of indelibly etched characters: among them, the strikingly beautiful, social-climbing Cindy Sanders; Boog Miller, the tackily-dressing millionaire good ole boy who patronizes Jack's business and who has more political muscle than a litter of lobbyists; Khaki Descartes, the pushy, brain-picking, Washington woman reporter; Freddy Fu, an undercover CIA agent working out of a greasy barbecue joint called The Cover-Up; and Jean Arber, the mother of two and a fledgling antique-store owner who can't quite figure out if she'll marry Jack or not. Wild, touching, and hilariously funny, "Cadillac Jack" is Larry McMurtry's raucous social satire of sex, politics, and love in the fast lane, peopled with Americans only he could render.
