Quote from : All the President's Men Book

Woodward said that he had told no one the name of Deep Throat. Mrs. Graham paused. 'Tell me,' she said. Woodward froze. He said he would give her the name if she wanted. He was praying she wouldn't press it. Mrs. Graham laughed, touched his arm and said she was only kidding, she didn't really want to carry that burden around with her. Woodward took a bite of his eggs, which were cold. -- Carl Bernstein, Bob Woodward
