Millions of people climb the grand marble staircase into New York's Metropolitan Museum of Art every year. But only a select few have unrestricted access to every nook and cranny. They're the guards in dark blue suits, keeping careful watch over this vast treasure house. Caught up in the early days of a glamorous journalism career, Patrick Bringley never thought he'd be one of them. Then his brother was diagnosed with fatal cancer and he needed to escape the mundane clamour of daily life. So he quit, and sought solace in the most beautiful place he knew. To his surprise, this temporary refuge becomes his home away from home for a decade. We follow him as he guards delicate treasures from Egypt to Rome, strolls the labyrinths beneath the galleries, and discovers how restorative art can be.
