In the world of casino gaming, larcenous souls tip the scales of fortune in their favor. Casinos don't stop players from cashing in if the win is honest. But if the rules in the game are bent, casinos counter the results. James "Jimmie Quick" Silver knows life on both sides of the fence. He was a dealer, a player, a winner, a loser and a fugitive run to earth. Now he's a high-tech-gadget toting servant for the house. He finds folks who scam the casino. They cheat or steal; they skip town on a bloated marker. But they leave clues for Jimmie and Dolly to find. When she isn't helping track down scum, Dolly dances in a North Las Vegas dive. Jimmie tracks the casino's current trio of bent blackjack players from Las Vegas to Palm Springs. When the suspects are traced to Puerto Rico, Jimmie and Dolly catch a plane to the Caribbean for a quick trip through the islands, ending up in Santo Domingo for the breathtaking finale.
