In the latest pulse-pounding thriller from Edgar and Barry Award finalist Mike Lawson, beloved Washington, DC, “troubleshooter” Joe DeMarco finds himself assigned an impossible case: help take down the president of the United States.

Brandon Cartwright was a rich guy worth a couple billion bucks—inherited, of course—meaning he hadn’t worked a day in his life. But he sure knew how to party, and the people he rubbed shoulders with were all sorts of rich and famous: politicians and movie stars and British royalty and Russian oligarchs. So when Brendan Cartwright is executed in his own home, the cops quickly conclude that he was most likely killed by one or more of the rich, powerful people he partied with.

But when John Mahoney, the former Speaker of the House, emerges from a clandestine meeting with the head of the National Archives, he learns there’s evidence suggesting that the President of the United States was somehow involved with Cartwright’s death. Mahoney needs someone who can investigate from the shadows—enter Joe DeMarco, Mahoney’s fixer.

DeMarco is no stranger to hunting down some of the very worst people Washington, DC, has to offer. In fact, he’s made a career of it. But as evidence continues to point towards the president, DeMarco is faced with an impossible situation: investigating a man who is quite literally untouchable.
