She read several more letters describing operations written out in technical detail. Faith sat silently, waiting.

Then quite suddenly Hester froze. She had read three operations for which the procedure was exactly the same. There was no diagnosis mentioned, no disease, no symptoms of pain or dysfunction at all. She went back and reread them very carefully. All three patients were women.

Then she knew what had caught her attention: they were three abortions-not because the mother's life was endangered, simply because for whatever personal reason she did not wish to bear the child. In each case Prudence had used exactly the same wording and recording of it-like a ritual.

Hesjer raced through the rest of the letters, coming closer to the present. She found seven more operations detailed in exactly the same way, word for word, and each time the patient's initials were given but not her name, and no physical description. That also was different from all other cases she had written up: in others she had described the patient in some detail, often with personal opinion added-such as: "an attractive woman" or "an overbearing man."

There was one obvious conclusion: Prudence knew of these operations, but she had not attended them herself. She had been told only sufficient to nurse them for the first few hours afterwards. She was keeping her notes for some other reason.

Blackmail! It was a cold, sick thought-but it was inescapable. This was her hold over Sir Herbert. This was why Sir Herbert had murdered her. She had tried to use her power, had tried once too hard, and he had stretched out his strong beautiful hands and put them around her neck-and tightened his hold until there was no breath in her!

Hester sat still in the small room with the light fading outside. She was suddenly completely cold, as if she had swallowed ice. No wonder he had looked dumbfounded when he had been accused of having an affair with Prudence. How ridiculously, absurdly far from the truth.

She had wanted him to help her study medicine, and had used her knowledge of his illegal operations to try to force him-and paid for it with her life.

She looked up at Faith.

Faith was watching her, her eyes intent on Hester's face.

"You know," she said simply. "What is it?"

Carefully and in detail Hester explained what she knew.

Faith sat ashen-faced, her eyes dark with horror.

"What are you going to do?" she said when Hester finished.

"Go to Oliver Rathbone and tell him," Hester answered.

"But he is defending Sir Herbert!" Faith was aghast. "He is on Sir Herbert's side. Why don't you go to Mr. Lovat-Smith?"

"With what?" Hester demanded. "This is not proof. We understand this only because we knew Prudence. Anyway, Lovat-Smith's case is closed. This isn't a new witness, or new evidence-it is only a new understanding of what the court has already heard. No, I'll go to Oliver. He may know what to do-please God!"

"He'll get away with it," Faith said desperately. "Do you-do you really think we are right?"

"Yes, I do. But I'm going to Oliver tonight. I suppose we could be mistaken-but… no-we are not. We are right" She was on her feet, scrambling to pick up her wrap, chosen during the warmth of the day and too thin for the chiller evening air.

"You can't go alone," Faith protested. "Where does he live?"

"Yes I can. This is no occasion for propriety. I must find a hansom. There is no time to lose. Thank you so much for letting me have these. I'll return them, I promise." And without waiting any longer she stuffed the letters in her rather large bag, hugged Faith Barker, and bolted out of the sitting room down the stairs and out into the cool, bustling street.

“I suppose so," Rathbone said dubiously, holding the sheaf of letters in his hand. "But medical school? A woman! Can she really have imagined that was possible?"

"Why not?" Hester said furiously. "She had all the skill and the brains, and a great deal more experience than most students when they start. In fact, than most when they finish!"

"But then…" he began, then met her eyes and stopped. Possibly he thought better of his argument, or more likely he saw the expression on her face and decided discretion was the better part of valor.

"Yes?" she demanded. "But what?"

"But did she have the intellectual stamina and the physical stomach to carry it through," he finished, looking at her warily.

"Oh I doubt that!" Her voice was scalding with sarcasm. "She was only a mere woman, after all. She managed to study on her own in the British Museum library, get out to the Crimea and survive there, on the battlefield and in the hospital. She remained and worked amid the carnage and mutilation, epidemic disease, filth, vermin, exhaustion, hunger, freezing cold, and obstructive army authority. I doubt she could manage a medical course at a university!"

"All right," he conceded. "It was a foolish thing to have said. I beg your pardon. But you are looking at it from her point of view. I am trying to see it, however mistaken they are, from that of the authorities who would-or would not-have allowed her in. And honestly, however unjust, I believe there is no chance whatsoever that they would."

"They might have," she said passionately, "if Sir Herbert had argued for her."

"We'll never know." He pursed his lips. "But it does shed a different light on it. It explains how he had no idea why she appeared to be in love with him." He frowned. "It also means he was less than honest with me. He must have known what she referred to."

"Less than honest!" she exploded, waving her hands in the air.

"Well, he should have told me he gave her some hope, however false, of being admitted to study medicine," he replied reasonably. "But perhaps he thought the jury would be less likely to believe that." He looked confused. "Which would make less of a motive for him. It is curious. I don't understand it."

"Dear God! I do!" She almost choked over the words. She wanted to shake him till his teeth rattled. "I read the rest of the letters myself-carefully. I know what they mean. I know what hold she had over him! He was performing abortions, and she had detailed notes of them- names of the patients and days, treatments-everything! He killed her, Oliver. He's guilty!"

He held out his hand, his face pale.

She pulled the letters out of her bag and gave them to him.

"It's not proof," she conceded. "If it had been, I'd have given them to Lovat-Smith. But once you know what it means, you understand it-and what must have happened. Faith Barker knows it's true. The chance to study and qualify properly is the only thing Prudence would have cared about enough to use her knowledge like that."

Without answering he read silently all the letters she had given him. It was nearly ten minutes before he looked up.

"You're right," he agreed. "It isn't proof."

"But he did it! He murdered her."

"Yes-I agree."

"What are you going to do?" she demanded furiously.

"I don't know."

"But you know he's guilty!"

"Yes… yes I do. But I am his advocate."

"But-" She stopped. There was finality in his face, and she accepted it, even though she did not understand. She nodded. "Yes-all right."

He smiled at her bleakly. "Thank you. Now I wish to think."

He called her a hansom, handed her up into it, and she rode home in wordless turmoil.

As Rathbone came into the cell Sir Herbert rose from the chair where he had been sitting. He looked calm, as if he had slept well and expected the day to bring him vindication at last. He looked at Rathbone apparently without seeing the total change in his manner.
