“Yes,” Hester replied. “It happens to many if they have been abandoned, put out of a job and have no reference to character-”

“Yes,” he cut her off. “Did this cause you to take any action, Mrs. Monk?”

“Yes.” She knew the judge’s tolerance would not last a great deal longer. “I was able to learn exactly where this brothel was, and by means of questioning, who the partner was who practiced the usury. I never learned exactly who carried out the beatings or the knifing.” She did not know if he wanted this part or not, but she added. “It does not continue any longer. We were able to put the brothel out of business and turn the house into better premises for the Coldbath refuge.”

He smiled very slightly. “Indeed. What happened to the usurer?”

“He was killed.” Did he want to know it was Baltimore? She stared at him, and could not tell.

“But his record of the debts?” he asked.

“We destroyed it.”

“Did you then know he was killed?”

“Yes… he was a client as well as the usurer. He took his own tastes too far, and one of the women, who was new to the trade, was so revolted by what he asked of her that she lashed out at him, and he fell backwards out of the window onto the pavement beneath, to his death.”

There was a rumble of profound emotion from the courtroom. Someone even cheered.

“Order!” the judge said loudly. “I will have order! I understand your outrage-indeed, I share it-but I will have respect for the law! Sir Oliver, this story is fearful, but I still see no connection to the death of Katrina Harcus, and Mr. Dalgarno’s guilt or innocence in the matter.”

Rathbone swiveled to face Hester again. “Mrs. Monk, among those records did you find those of the young woman, Kitty, who came to you with cuts and bruises on the night Nolan Baltimore’s body was discovered in Leather Lane, near Coldbath Square?”

“Yes.”

“Was she among the once-respectable young women who had been reduced to selling her body for a particularly repulsive type of abuse in order to pay the ever-mounting debt of such high rates of usury that she could never be free of it?”

“Yes.”

“Could you describe her for the court, Mrs. Monk? What did she look like?”

Now she understood. It was so terrible she felt sick. The room swam around her as if she were at sea, the silence was a roar like waves. She heard Rathbone’s voice only distantly.

“Mrs. Monk? Are you all right?”

She clung onto the rails, gripping them hard so the physical pain would bring her back to the moment.

“Mrs. Monk!”

“She was…” She gulped and licked her dry lips. “She was fairly tall, very handsome. She had dark hair and golden brown eyes… very beautiful. She gave me the name of Kitty… and the records said Kitty Hillyer…”

Rathbone turned very slowly to face the judge. “My lord, I believe we now know where Katrina Harcus obtained the money to dress as well as was necessary for a handsome but penniless young woman, born illegitimate, left destitute when her father died and his promised legacy did not come. She traveled south to London to try and make a fortunate marriage. However, within the space of two months her mother died, her fiancé rejected her for a richer bride, and her debts became so urgent she was drawn into the most repellent form of prostitution to satisfy the usurer, her father’s colleague, a man she had known as a child and to whom she had turned for help in a strange city, and who had so betrayed her. Perhaps because of who he was, his demands revolted her so intensely that she fought him off, to his death.”

The judge commanded silence in the growing swell of fury within the room, but it was several long seconds before he received it, so intense was the wave of emotion in the room. He nodded to Rathbone to continue.

“And that very night when she was taken by two other prostitutes to Coldbath Square to have her own injuries treated,” Rathbone resumed, facing the jury now, “who should be the nurse who helped her, but the wife of the man who was, in her mind, the author of her grief, all the injustices against her from childhood? She heard the name of Mrs. Monk, and the description both of Monk’s appearance and his nature, and his new occupation. I believe from that moment on she began to plan a terrible revenge.”

A hideous, unbelievable thought danced at the edge of Hester’s mind.

Fowler stood up, but did not know what to say. No one was listening to him anyway.

Hester could think only of Monk. Dalgarno, the jury, even Rathbone, melted from her vision. Monk was sitting motionless, his eyes wide and hollow, his skin bleached of every vestige of color. Margaret had moved closer to him, but she had no idea what to do to offer any word or gesture.

“Katrina Harcus had nothing left,” Rathbone said quietly, but in the now total silence every word was clear. “Her mother was dead, the man she loved had deserted her, and she had no hope of ever winning him back because there was, only too obviously, nothing to win. He was incapable of love or even of honor. She was in debt beyond her means ever to repay, and she had sold her body to a particularly degraded form of prostitution from which she may well have felt she would never again be clean. And now she was also guilty of a man’s death. She was wise enough in the ways of the world to know that society would see it as murder, regardless of the provocation she endured, or that she may not have intended him to die. It would be only a matter of time before the police found her, and she would live in fear of it for the rest of her life.”

He spread his hands. “The one thing left for her was revenge. And fate handed her the perfect opportunity for that when she found Mrs. Monk in Coldbath Square. She knew all about the original fraud in Liverpool for which her father, Arrol Dundas, was convicted. She created the impression of another fraud almost exactly like it, knowing that Monk would not be able to resist the temptation to investigate it. The likelihood of his recognizing her was remote. She had been a child of eight when he had last seen her, if indeed he saw her at all.”

He looked from the judge to the jury. “She took good care that they met in public, where they would be observed by impartial witnesses. She may have made certain Monk would be there at her house in Cuthbert Street that night. We can call Mr. Monk to the stand to testify of that, if necessary.” He drew in a deep breath and faced the judge again. “That, my lord, is the purpose of Mr. Garstang’s so very exact testimony. He saw her face as she fell. Inspector Runcorn described her on the ground, on her side… not her back. No one saw two distinct figures, and the cloak was left on the roof, my lord, because she was not thrown or pushed off-she jumped!”

He was momentarily prevented from continuing by the uproar of amazement, disbelief and horror that engulfed the room. But it faded quickly as the terrible truth sank into understanding, and then belief.

When he resumed, his voice fell into utter silence.

“My lord, Michael Dalgarno is innocent of murder, because there was no murder… at least not of Katrina Harcus when she went off the roof of her house and plunged to her death. As for the night she killed Nolan Baltimore, we shall-”

He was prevented from saying whatever he had intended by Livia, now lurching to her feet, her face gray.

“That’s not true!” she screamed. “That’s a wicked thing to say! It’s a lie!” Her voice choked in a sob. “An evil… terrible thing to say! My father…” She lashed her arms left and right as if fighting her way through some physical obstacle. “My father would never have done anything like that! It’s… it’s filthy! It’s disgusting! I saw those women-they were…” The tears were streaming down her face. “They were broken, bleeding… whoever did that was monstrous!”

Rathbone looked wretched. He struggled for something, anything, to say to ease her grief, but there was nothing left.
