Charles McCarry is considered by many to be the master of world-class spy fiction, garnering praise from peers and critics alike for his riveting novels. Christopher Buckley wrote that McCarry "is not only one of the best writers in America but one of the most important. He dazzles, from epigraph to epilogue," and the Los Angeles Times hailed his work as "first rate, in the tradition of the best espionage fiction, John Buchan to Eric Ambler and John le Carré." In this magnificent new novel, which the Washington Post named a Best Book of the Year, McCarry returns to the world of his legendary character Paul Christopher—who has mysteriously disappeared. Led by Christopher’s cousin Horace, a group of his retired colleagues—the "Old Boys" from the Outfit—embark on a thrilling worldwide search for the master spy and an ancient scroll that may reveal an unspeakably dangerous truth.
