Millions of people climb the grand marble staircase to visit the Metropolitan Museum of Art every year. But only a select few enjoy unrestricted access to its every nook and cranny. They're the guards who roam unobtrusively in dark blue suits, keeping a watchful eye on the two-million-square-foot treasure house. Caught up in his glamorous fledgling career at the New Torker, Patrick Bringley never thought he'd be one of them. Then his older brother was diagnosed with terminal cancer and he found himself needing to escape the mundane clamor of daily life. So he quit the New Torker and sought solace in the most beautiful place he knew. To his surprise and the reader's delight, this temporary refuge becomes Bringley's home away from home for a decade. We follow him as he guards delicate treasures from Egypt and Rome, strolls the labyrinths beneath the galleries, wears out nine pairs of company shoes, and marvels at the beautiful works in his care. Bringley enters the museum as a ghost, silent and almost invisible, but soon finds his voice and his tribe: the artworks and their creators and the gracious, ebullient subculture of museum guards-a gorgeous mosaic of artists, musicians, blue-collar stalwarts, immigrants, cutups, and dreamers. As his bonds with his colleagues and the art grow, he comes to understand how fortunate he is to be walled off in this little world, and how much it resembles the best aspects of the larger world to which he gradually, gratefully returns.
