Aldo Cassidy is a cautious man. He has a pleasant family, drives a safe, expensive car and wears luxurious clothes. But his soothing existence is upended when he meets Shamus and Helen - a dazzling, bohemian couple who are everything he is not. As he is drawn into their reckless and unpredictable orbit, all that Cassidy thought he understood about his orderly life begins to unravel. Told with le Carre's lacerating wit and penetrating observation, The Naive and Sentimental Lover is an acerbic satire of middle-class hypocrisies.
