Jackson Bryant, the millionaire plaintiff lawyer who turned to pro bono work in Dead Peasants, is caught up in the collision of money and politics when he receives a call from his old army buddy Walt Frazier. Walt needs his assistance in evaluating security for Texas Governor Rob Lardner at a Halloween costume fundraiser thrown by one of the nation's richest Republican billionaires at his mansion in Fort Worth.

Miriam Van Zandt is the best marksman among The Alamo Defenders, an anti-government militia group in West Texas. She attends the fundraiser dressed as a cat burglar--wounds the governor and murders the host's brother, another Republican billionaire. She is shot in the leg but manages to escape.



Jack is appointed special prosecutor and must call on the Texas DPS SWAT team to track Van Zandt and attack The Alamo Defenders' compound in a lonely part of West Texas. Van Zandt's father, founder of the Defenders, is killed in the attack and Miriam is left in a coma. The authorities declare victory and close the case-but Jack knows better. The person behind the Halloween massacre has yet to be caught. When Walt and the protective detail are sued by the fundraiser host and the widow of the dead man, Jack follows the dark money of political contributions from the Cayman Islands to Washington to Eastern Europe, New York and New Orleans to track the real killer and absolve his friend and the Protective Detail of responsibility for the massacre.

Dark Money is a thriller, a mystery and an expose of the corruption of money in politics caused by the Supreme Court's decision in Citizens United.
