He smiled at Rathbone and called his first witness, Sergeant Michael Robb.
Rathbone watched as Robb climbed the short staircase to the witness stand and faced the court. He looked unhappy and extraordinarily young. He must have been in his mid-twenties, but he had the scrubbed and brushed look of a child sent off to Sunday school and who would far rather be almost anywhere else.
Tobias sauntered out into the middle of the open space of the floor with the jury on one side, the witness ahead of him, and the judge to his right, high up against the wall in his magnificent seat, surrounded by panels of softly gleaming wood and padded red velvet.
"Sergeant Robb," Tobias began politely, "this whole case is very distressing. No decent man likes to imagine two women, especially when one is young and agreeable to look upon and the other is entrusted with the care of the sick"—he lifted his hand very slightly towards the dock—"would be capable of conspiring together to commit cold-blooded murder for gain. Fortunately, it is not your task, nor mine either, to determine if this is indeed what happened." He turned with a graceful gesture to face the jury and gave a little bow in their direction. "It is the awful duty of these twelve good men and true, and I do not envy them. Justice is a mighty weight. It takes a strong man, a brave man, an honest man, to bear it."
Rathbone was tempted to interrupt this piece of blatant flattery, but he knew Tobias would be only too happy if he did. He remained in his seat, nodding very slightly as if he agreed.
Tobias turned back to Robb. "All we need from you is a simple, exact account of the facts you know. May we begin with the discovery of the body of James Treadwell?"
Robb stood to attention. Rathbone wondered if it was as apparent to the jury as it was to him how much Robb disliked his task. Would they imagine it was repugnance for the crime, or would they know, as he did, that it was a deeper knowledge of complex tragedy, right and wrong so inextricably mixed he could not single out one thread?
How did people judge? On instinct? Intelligence? Previous knowledge and experience? Emotion? How was evidence interpreted? How often he had seen two people describe a single chain of events and draw utterly different conclusions from it.
Robb began by talking with bare, almost schoolboy simplicity of having been called out to see the dead body of a man who had apparently died of a blow to the head.
"So you decided immediately that he was the victim of murder?" Tobias said with surprise and evident satisfaction. He barely glanced at Rathbone, as if he half expected to be interrupted and took it as a sign of Rathbone’s foreknowledge of defeat that he was not.
Robb breathed in deeply. "From the kind of marks on his clothes, sir, I didn’t think he’d fallen off a coach or carriage, or been struck by one that maybe didn’t see him in the dark."
"Very perceptive of you. You judged the matter of great seriousness right from the outset?"
"Death is always serious," Robb answered.
"Of course. But murder has a gravity that accident does not. It is a dark and dreadful thing, a violation of our deepest moral order. Accident is tragic, but it is mischance. Murder is evil!"
Robb’s face was pink. "With respect, sir, I thought you said you and I were not here to judge, just to establish the facts. If you don’t mind, sir, I’d prefer to stick to that."
There was a murmur around the court.
Rathbone allowed himself to smile; indeed, he could not help it.
Tobias controlled his temper with grace, but it cost him an effort. Rathbone could see it in the angle of his shoulders and the pull of the cloth in his expensive coat.
"I stand corrected," he conceded. "By all means, let us have the bare facts. Will you describe this dead man that you found. Was he young or old? In good health or ill? Let us see him through your eyes, Sergeant Robb. Let us feel as you did when you stood on the pavement and stared down at this man, so lately alive and full of hopes and dreams, and so violently torn from them." He spread his arms wide in invitation. "Take us with you."
Robb stared at him glumly. Never once did he lift his glance towards the two women sitting white-faced and motionless in the dock. Nor did he look beyond Tobias and Rathbone to search the audience for other faces familiar to him: Monk or Hester.
"He was fairly ordinary. It was difficult to tell his height lying down. He had straight hair, strong hands, callused as if he’d held reins often enough."
"Any signs of a fight?" Tobias cut in. "Any bruises or cuts as if he had tried to defend himself?"
"I saw none. Just the grazes on his hands—from crawling."
"I shall naturally ask the surgeon also, but thank you for your observation. Exactly where was this poor man, Sergeant?"
"On the pathway between number five and number six on Green Man Hill, near Hampstead Heath."
"And which way was he facing?"
"Towards number five."
"And is that where he was killed?"
"I don’t think so. He looked to have crawled some distance. His trouser knees were all torn and muddy, and his elbows in places."
"How far? Can you tell?"
"No. At least two or three hundred yards, maybe more."
"I see. What did you do then, Sergeant?"
Step by step, Tobias drew from Robb the account of finding the carriage and the horses, and presuming they were connected with the dead man. Then he led him through Monk’s arrival, seeking someone answering the dead man’s description.
"How very interesting!" Tobias said with triumph. "Presumably, you took this Mr. Monk to look at your corpse?"
"Yes sir."
"And did he identify him?"
"No sir. He couldn’t say. But he fetched two gentlemen from Bayswater who said he was James Treadwell, who had been their coachman."
"And the names of these gentlemen?"
"Major Harry Stourbridge and his son, Mr. Lucius Stourbridge."
There was a rustle of movement in the court as people’s attention was caught. Several straightened in their seats. "The same Lucius Stourbridge who is the son of Mrs. Verona Stourbridge and who was engaged to marry Mrs. Miriam Gardiner?"
More movement in the gallery. Two women craned forward to stare at the dock.
"Yes sir," Robb answered.
"And when was Treadwell last seen alive, and by whom?"
Reluctantly, Robb told of Miriam’s flight from the garden party, Monk’s duplicity on the matter, and how first Monk had tracked down Miriam, and then how Robb had himself. There was nothing Rathbone could do to stop him.
"Most interesting," Tobias said sagely. "And did Mrs. Gardiner give you a satisfactory account of her flight from Bayswater and any reason for this most strange behavior?"
"No sir."
"Did she tell you who had killed Treadwell? I assume you did ask her?"
"I did, and no, she did not give me any answer, except to say she did not do it."
"And did you believe her?"
Rathbone half rose to his feet.
The judge glanced at him.
Tobias smiled. "Perhaps that could be better phrased. Sergeant Robb, did you subsequently arrest Mrs. Gardiner for the murder of James Treadwell?"
"Yes, I did."
Tobias raised his eyebrows. "But you have not charged her with it!"
Robb’s face was tight and miserable. "She’s charged with conspiracy..."
"That you should be sad about such a fearful tragedy is very proper, Sergeant," Tobias observed, staring at him. "But you seem more than that, you seem reluctant, as if you do this against your will. Why is that, Sergeant Robb?"
Rathbone’s mind raced. Should he object that this was irrelevant, personal? He had intended to use Robb’s high opinion of Cleo, his knowledge of her motives, as his only weapon in mitigation. Now Tobias had stolen it. He could hardly object now and then raise it himself later. Even if he did so obliquely, Tobias himself would then object.
