" We’re used to the film versions of psychopaths. The clearly crazies. But most psychopaths are clever. They have to be. They know how to mimic human behavior. How to pretend to care, while not actually feeling anything except perhaps rage and an overwhelming and near-perpetual sense of entitlement. That they’ve been wronged. They get what they want mostly through manipulation. "

― Louise Penny , Glass Houses (Chief Inspector Armand Gamache, #13)
