A malevolent expression gathered on Professor Atherton’s face. “Bugger’n’blast, son, in days gone by I’d’ve boxed your ears for saying something so bloody-minded.”

“You didn’t answer the question. Did Tracy have a brother?”

The professor’s expression darkened further. “You mean a half brother.”

Chrissie took a step toward the two men, who were now faced off like street fighters about to settle a grudge. “Adam, why are you-?”

“Don’t get all gutted up over nothing.” Her father waved away her protest. And then to Bourne: “You’re asking me if I had sexual relations with another woman and something came of it?”

“That’s right.”

“Never did,” Professor Atherton said. “I loved the girls’ mother and I’ve been faithful to her for longer than I care to remember.” He shook his head. “I think you’ve made rather a hash of this.”

Bourne was unfazed. “Tracy worked for a dangerous man. I had to ask myself why because it seemed doubtful that she would work for him willingly. Then Chrissie provided a partial answer. Tracy told this man she had a brother who was in trouble.”

At once Professor Atherton’s demeanor altered radically. All color drained out of his face; he might have fallen if Chrissie hadn’t stepped to his side to support him. With some difficulty she got him to sit down in the chair opposite Marks.

“Dad?” She knelt beside him, his clammy hand in hers. “What is this? Is there a brother I don’t know about?”

The old man kept shaking his head. “I had no idea she knew,” he mumbled as if to himself. “How the bloody hell did she find out?”

“So it’s true.” Chrissie shot Bourne a glance, then redirected her attention to her father. “Why didn’t you and Mum tell us?”

Professor Atherton sighed deeply, then passed a hand across his sweating brow. He looked at his daughter blankly, as if he didn’t recognize her, or he was expecting to see someone else.

“I don’t want to talk about it.”

“But you must.” She seemed to rise up, stiffening her spine, and she leaned in toward him as if to lend her words more weight. “You have no choice now, Dad. You have to tell me about him.”

Her father remained silent, impassive now, as if free of a fever that had gripped him.

“What’s his name?” she implored. “Can’t you tell me that much?”

Her father’s eyes would not meet hers. “He had no name.”

Chrissie sat back, as if he had slapped her across the face. “I don’t understand.”

“And why would you?” Professor Atherton said. “Your brother was born dead.”

JALAL ESSAI WAS a marked man and he knew it. As he sat on a bridge chair he’d opened up in his darkened bedroom, he considered these factors: Breaking with Severus Domna had not been an easy decision-or rather, while the decision had been easy, the actual implementation had been difficult. But then it was always difficult, Essai thought, deliberately putting oneself in harm’s way. He had not acted on his decision until he had worked out the methods of implementation, drawing up a list in his mind of all the possible paths he could take, then eliminating them one by one until he reached the one with the fewest objections, the most acceptable level of risk, and the best odds of success. This methodical approach was how he arrived at every decision: The process was the most logical. Also, it had the added benefit of calming his mind, not unlike his prayers to Allah, or contemplating a Zen koan. The empty mind fills itself with possibilities unavailable to others.

So he sat, absolutely still, within the darkness of his apartment, the blackness of his bedroom where all the blinds were drawn against nighttime’s streetlights and the passing headlights of the occasional car or truck. Night, and the threat of night. Night was to him what a cup of espresso was to others, a calm and satisfying state of reflection. He could navigate his way through darkness, even nightmares, because Allah had blessed with the light of the true believer.

It was 3 AM. He knew what was coming, which was why he had chosen not to run. A runner makes an excellent target as he leaves his own territory. He stumbles-and he dies. Essai did not intend to stumble. Instead he had prepared his bedroom for the inevitable, and he was willing-content even-to remain in place until the enemy showed his face.

He heard the sound first. A tiny scratching, as if of mice, from the living room, in the direction of the front door. The sound very quickly ceased, but he knew the enemy must have picked the lock on his door, because someone was in the apartment. Still, he did not move. There was no reason to move. He cast his gaze on the bed, where a lump under the covers revealed to his enemy’s eyes the presence of a sleeping body.

The quality of the darkness changed, deepening, becoming thicker, dense with the pulse of another human being. Essai’s focus narrowed even more. His enemy, now in the kill zone, bent over the bed.

Essai felt the motion as a stirring of the air as his enemy drew out a dagger and plunged it into the figure sleeping in the bed. At once the plastic skin punctured, spraying the would-be killer with a geyser of battery acid with which Essai had filled the inflatable sex toy.

His enemy reacted in predictable fashion by falling backward, limbs pinwheeling. On the floor he tried and failed to wipe the acid off his face, neck, and chest. This action only served to smear the acid over more of his face, neck, and chest. He gasped, but because the acid was eating his lips and tongue he could not get out any words or even a scream. A nightmare scenario for him, Essai thought, as he rose from the chair at last.

Kneeling over the enemy-the man Severus Domna had sent to kill him for his disloyalty-he smiled the smile of the just, the righteous in Allah’s beneficent eyes, and putting a forefinger against his lips he whispered, “Shhhhh,” so low that only he and his enemy could hear.

Then he took up the assassin’s dagger and picked his way to the doorway into the hall. Pressing himself against the wall, he waited, emptying his mind of expectation. Into this divine emptiness came the most probable route the second man would take. He knew there was a second man, just as he knew his assassin would not use a pistol to kill him, because these were the two major methods of operation Severus Domna employed: stealth and backup. Methods he himself had used in going after Jason Bourne and the ring.

A diagonal shadow falling across the width of the hall bore out his thesis. Now he knew where the second assassin was, or rather had been, because he was on the move. His compatriot had had enough time to effect the kill, and now he was closing the gap between them to determine if anything was amiss.

Something certainly was amiss, a fact confirmed to him as the dagger, thrown with great accuracy by Essai, penetrated his chest between two ribs and pierced his heart. He fell heavily, like a wildebeest taken down by a lion. Essai approached him, knelt, and determined there was no pulse, no life left. Then he returned to his bedroom, where the first assassin was writhing on the floor with ever-more-uncoordinated movements.

Snapping on a lamp, he studied the man’s face. He did not recognize him, but then he didn’t expect to. Severus Domna would not have sent anyone he could identify on sight. Squatting down beside the man, he said, “My friend, I pity you. I pity you because I have chosen not to end your life and therefore your suffering. Instead, I will leave you as you are.”

Pulling out a cell phone burner, he dialed a local number.

“Yes?” Benjamin El-Arian said.

“Delivery for you to pick up,” Essai said.

“You must be mistaken. I didn’t order anything.”

Essai put the cell to the assassin’s mouth, and he made sounds like a cow in distress.
