Twenty-one years ago, when I first heard Mia Farrow had accused me of child molestation, I found the idea so ludicrous I didn't give it a second thought. We were involved in a terribly acrimonious breakup, with great enmity between us and a custody battle slowly gathering energy. The self-serving transparency of her malevolence seemed so obvious I didn't even hire a lawyer to defend myself. It was my show business attorney who told me she was bringing the accusation to the police and I would need a criminal lawyer.
