The Seven of Diamonds — Max Brand

TIRREL RODE INTO LOS CAVALLOS FLUSH WITH A POKER WIN--AND TARGETED FOR DEATH!

Wearing another man's clothes and flashing a diamond-studded stickpin, Tirrel didn't know he'd been set up. The man he'd bested in cards had stolen the diamonds from Brander, a dangerous outlaw. Brander had killed one man for the diamonds, and a hidden horde of cash and jewels. Now he was gunning for Tirrell--in a showdown that would shatter the town with the roar of bullets and a fight to the bloody end!
