Diamondback 06: Made in Spades

After a casual dalliance with a young woman in New Mexico, Dex Yancey discovers that her family—the Espinoza clan—have lost their wealth and are too proud to accept handouts. They are being besieged by a rowdy group of badmen employed by Englishman Sir David Manchester, who wants to develop his own cattle ranch on Espinoza land.
 
Seeing that Dex is friendly with the Espinozas, Manchester hires him to persuade the family to sell their homestead. But Dex has a better idea, one that will ensure the land remains with the Espinozas, and one that will cost Manchester his fortune.
 
Smooth as a snake, and twice as slippery, Dex Yancey is the con man’s con man. Whether the game is cards, dice, or gambling with your life, Dex is ready to play against the odds—and win. Ladies love him. Gamblers hate him. But nobody puts one over on Dex.
