When she arrives at the famed Barbizon Hotel in 1952, Darby McLaughlin is everything her hall mates aren't: plain, self-conscious, homesick and convinced she doesn't belong. Yet when she befriends Esme, a Barbizon maid, she's introduced to an entirely new, colourful yet seedy side of New York City. Over half a century later, journalist Rose Lewin hears rumours of Darby's involvement in a deadly skirmish with a hotel maid. A perfect distraction from her own imploding personal life, Rose becomes obsessed with finding the truth about what really happened at the hotel.
