She loves keeping her readers guessing, but also appealing to their senses with charming scenes straight from East Hampton, quirky characters and mouthwatering food descriptions. When she is not writing her latest novel, Doyle is sure to be part of one of a myriad of projects, which may include co-writing with another author, doing magazine articles, interviewing celebrities, arranging events or cooking up a storm in the kitchen. As our Author of the Day, Doyle talks about why her books are so yummy, gives us some insights in the character of Antonia Bingham and reveals why East Hampton is her favorite place in the world.
