Drawing Dead — Rick Gadziola

An ex-cop gambles with his life in Las Vegas in this “fast-moving” mystery (Booklist).
 
Jake Morgan, who left the Boston police force and wound up in Vegas thanks to his taste for games of chance, finds himself hitting it off with a beautiful high roller in her sumptuous suite. Then an assassin enters and breaks the lady's bliss by popping two lead pills into her forehead.
 
Before Morgan knows it, he's not only being grilled over the murder, he's also targeted by a femme fatale and caught in the crossfire between two groups of dirty cops. Now he's not sure who he can trust, in this action-packed crime thriller.
