“Proving it,” he said coolly. “But I will go to see your father tomorrow and ask how hard he wishes me to press the issue. He has until Monday morning to decide. As it is now, I think we have a good chance of reasonable doubt. I could call him to testify, and he can swear his innocence, but that will allow Winchester the opportunity to cross-question him. He may prefer not to do that. It is his choice, not yours or mine.” He put a finality into his voice, closing the subject from any further discussion. He sounded cold, and he knew it, but he felt cold inside, as if a door had been shut, and he did not know how to open it again.

IN THE MORNING HE went to see Arthur Ballinger in Newgate Prison. He had to wait some little time before at last Ballinger was brought to see him. In the gray light he looked tired, and for the first time Rathbone was acutely aware of how afraid he was. Pity twisted inside Rathbone for Margaret, and he wished he had been gentler with her, but he did not know now how to retrace his steps.

“Oliver!” Ballinger said sharply. “Why are you here? I thought it was going well?”

“It is,” Rathbone replied. Why did this man make him feel so uncomfortable? He had spoken to scores of clients in circumstances like these, both the guilty and the innocent. He cleared his throat. “I need to know if you wish to testify yourself or not. You don’t need to make up your mind until Monday morning, but you must give it very serious consideration.”

“Why wouldn’t I?”

“Because it will give Winchester the opportunity to cross-question you, and I can’t protect you from anything he says, nor can I foresee what it might be. Don’t underestimate him. As it is, I believe we have a very good chance of a verdict of not guilty, because there is more than reasonable doubt.”

“Doubt?” Ballinger said unhappily. “Reasonable doubt is the same as saying they believe I am guilty but they can’t prove it. I need ‘not guilty,’ Oliver, with certainty.” He took a breath. “I need them to believe that someone else killed that wretched creature.”

“They will say ‘not guilty,’ ” Rathbone assured him. “And you cannot be charged again. It is finished.”
