It's Christmas week when Sabrina Post knocks on the door of the Vanderbilt Suite at the Plaza Hotel in New York City, ready to accept the ghostwriting position for the memoir of Grayson Prescott, a famous art dealer. What promises to be a perfect week is complicated when Sabrina meets Ian Westing, a handsome British visitor, at the hotel bar. When Ian assumes Sabrina is another wealthy guest at the hotel, she doesn't correct him -- a decision she doesn't regret after learning that Ian is a member of the British aristocracy. But things are not what they seem.
