In his acclaimed #1 bestseller Dark Towers, David Enrich presented the never-before-told saga of how Deutsche Bank became the global face of financial recklessness and criminality. Now Enrich turns his eye towards the world of “Big Law” and the nearly unchecked influence these firms wield to shield the wealthy and powerful—and bury their secrets. To tell this story, Enrich focuses on Jones Day, one of the world’s largest law firms. Jones Day’s narrative arc—founded in Cleveland in 1893, it became the first law firm to expand nationally and is now a global juggernaut with deep ties to corporate interests and conservative politics—is a powerful encapsulation of the changes that have swept the legal industry in recent decades.

Since 2016, Jones Day has been in the spotlight for representing Donald Trump and his campaigns (and now his PACs)—and for the fleet of Jones Day attorneys who joined his administration, including White House Counsel Don McGahn. Jones Day helped Trump fend off the Mueller investigation; challenged Obamacare; defended Trump’s Muslim ban and border policies; and handled Trump’s judicial nominations. Jones Day even laid some of the legal groundwork for Trump to challenge the legitimacy of the 2020 election.

But the Trump work is but one chapter in the firm’s checkered history. Jones Day, like many of its peers, have become highly effective enablers of the business world’s worst misbehavior. The firm has for decades represented Big Tobacco in its fight to avoid liability for its products. Jones Day worked tirelessly for the Catholic Church as it tried to minimize its sexual-abuse scandals. And for Purdue Pharma, the maker of OxyContin, as it sought to protect its right to make and market its dangerously addictive drug. And for Fox News as it waged war against employees who were the victims of sexual harassment and retaliation. And for Russian oligarchs as their companies sought to expand internationally.
