“ There had been an all-night conference at the Butler home, and Mr. Butler, in a frenzy at finding himself a dupe, had called the butler from bed and forcibly ejected Fleming and Schwartz from the house. Ellen Butler had been horrified, sickened by what she regarded as the vulgarity of the occurrence. But her loyalty to her husband never wavered.
Butler was one honest man against a complete organization of unscrupulous ones. ”

“ She tried to get away, to run, even to scream—then she fainted. It was gray dawn when she recovered her senses and got back to the hotel room she had taken under an assumed name.
By night she was quieter. She read the news of Fleming's death in the papers, and she gloated over it. But there was more to be done; she was only beginning. She meant to ruin Schwartz, to kill his credit, to fell him with the club of public disfavor. Wardrop had told her that her husband's letters were with other papers at the Monmouth Avenue house, where he could not get them. ”

“ Normally a shrinking, nervous woman, she became cold, passionless, deliberate in her revenge. To disgrace Schwartz and Fleming was her original intention. But she could not get the papers.
She resorted to hounding Fleming, meaning to drive him to suicide. And she chose a method that had more nearly driven him to madness. Wherever he turned he found the figures eleven twenty-two C. Sometimes just the number, without the letter. It had been Henry Butler's cell number during his imprisonment, and if they were graven on his wife's soul, they burned themselves in lines of fire on Fleming's brain. ”
