A patron loved David Baldacci’s The Collectors. Here’s a synopsis from Amazon:
“People are dropping dead in Washington, D.C. First the Speaker of the House falls victim to a hitman in a carefully orchestrated murder in front of dozens of the city’s power elite. Next, the director of the Library of Congress’s Rare Books Room dies in a book vault, but no one knows how. Caleb Shaw, Camel Club member, nearly falls victim, too. Across the country, a gifted con woman assembles an A-list team to pull off one of the most audacious scams ever, against one of the most dangerous men in the world. When the worlds of Washington and the elite con collide head-on, the Camel Club finds itself teamed with a person they don’t really trust but whose skill helps them unravel a secret that threatens to bring America to its knees.”
