To solve Rhode Island's budget crisis, the state's colorful governor, Attila the Nun, wants to legalize sports gambling; but her plan has unexpected consequences. Organized crime, professional sports leagues, and others who have a lot to lose—or gain—if gambling is made legal flood the state with money to buy the votes of state legislators.

Liam Mulligan, investigative reporter for The Providence Dispatch, wants to investigate, but his bottom-feeding corporate bosses at the dying newspaper have no interest in serious reporting. So Mulligan goes rogue, digging into the story on his own time. When a powerful state legislator turns up dead, an out-of-state bag man gets shot, and his cash-stuffed briefcase goes missing, Mulligan finds himself the target of shadowy forces who seek to derail his investigation by destroying his career, his reputation, and perhaps even his life.
Bruce DeSilva's A Scourge of Vipers is at once a suspenseful crime story and a serious exploration of the hypocrisy surrounding sports gambling and the corrupting influence of big money on politics.
