Gypsy Hearts — Robert Eversz

"Richard Milhous "Nix" Miller, prodigal son of a California used-car dealer, is a small-time con man and a master at deluding himself and others. Posing as a Hollywood scriptwriter so that he can more easily pick the purses of the women he meets in Prague's cafes and nightclubs, he lives a fairly uneventful life until smitten by a cool, mysterious Danish beauty named Monika. Possibly a princess, possibly part Gypsy, Monika is clearly more than Nix's match as a con artist. After he eliminates her boorish lover, Nix joins her in an escalating series of cons that spin quickly and frighteningly out of control. Cinematic in both style and tone, the novel seems like a cross between an elaborately plotted comedy and film noir." from Library Journal
