And Never Let Her Go: Thomas Capano: The Deadly Seducer book by Ann Rule

From America's most celebrated true-crime writer comes the heartbreaking real-life drama of a doomed young woman hopelessly trapped in a web of sexual intrigue, political manipulation and emotional deception by her charming and successful - but ultimately deadly - lover. In the most complex and shocking book of her long career, Ann Rule delves into the motivation that drove a seemingly successful man to kill, and she explores hitherto unknown aspects of a fatal affair between a beautiful young woman who moved confidently in the heady world of the upper echelons of government and a widely admired millionaire attorney who was an immensely popular political figure. Ann Rule brilliantly traces the lives of both Ann Marie Fahey and Tommy Capano as she discloses the intimate details of their ill-fated bonding. A vulnerable, trusting woman becomes spellbound by a charming, duplicitous married man, and what begins as a seemingly unremarkable affair is slowly transformed into an obsessive, convoluted and deadly relationship.
