Bill Pronzini. Jackpot (1990) 213 pp.
Publisher’s description: “Why would a successful, good-looking young man, who had just won two hundred thousand dollars at a Lake Tahoe casino, kill himself? That’s the question Nameless asks himself when he finds a friend’s brother dead—an apparent suicide. Was more than luck involved in his windfall? Or was his good fortune reason enough for murder? The investigation takes Nameless inside the seamy and dangerous world of high-stakes gambling and mob-run casinos—and into the middle of a complex scam that has left at least one man in his grave, with others, including Nameless, odds-on favorites to follow.”
Setting: San Francisco; Lake Tahoe
