“Down there,” Sienna whispered, pointing into the obscurity below them. “At the edge of the frame. It’s got to be mounted to the wall. It should hold me.”
Before Langdon could protest, Sienna was climbing down off the strut, using a series of supporting beams as a ladder. She eased herself down onto the edge of the wooden lacunar. It creaked once, but held. Then, inching along the wall, Sienna began moving in Langdon’s direction as if she were inching across the ledge of a high building. The lacunar creaked again.
Thin ice, Langdon thought. Stay near shore.
As Sienna reached the halfway point, approaching the strut on which he stood in the darkness, Langdon felt a sudden renewed hope that they might indeed get out of here in time.
Suddenly, somewhere in the darkness ahead, a door slammed and he heard fast-moving footsteps approaching along the walkway. The beam of a flashlight now appeared, sweeping the area, getting closer every second. Langdon felt his hopes sink. Someone was coming their way—moving along the main walkway and cutting off their escape route.
“Sienna, keep going,” he whispered, reacting on instinct. “Continue the entire length of the wall. There’s an exit at the far end. I’ll run interference.”
“No!” Sienna whispered urgently. “Robert, come back!”
But Langdon was already on the move, heading back along the strut toward the central spine of the garret, leaving Sienna in the darkness, inching across the sidewall, eight feet below him.
When Langdon arrived at the center of the garret, a faceless silhouette with a flashlight had just arrived on the raised viewing platform. The person halted at the low guardrail and aimed the flashlight beam down into Langdon’s eyes.
The glare was blinding, and Langdon immediately raised his arms in surrender. He could not have felt more vulnerable—balanced high above the Hall of the Five Hundred, blinded by a bright light.
Langdon waited for a gunshot or for an authoritative command, but there was only silence. After a moment the beam swung away from his face and began probing the darkness behind him, apparently looking for something … or someone else. As the beam left his eyes, Langdon could just make out the silhouette of the person now blocking his escape route. It was a woman, lean and dressed all in black. He had no doubt that beneath her baseball cap was a head of spiked hair.
Langdon’s muscles tightened instinctively as his mind flooded with images of Dr. Marconi dying on the hospital floor.
She found me. She’s here to finish the job.
Langdon flashed on an image of Greek free divers swimming deep into a tunnel, far past the point of no return, and then colliding with a stony dead end.
The assassin swung her flashlight beam back down into Langdon’s eyes.
“Mr. Langdon,” she whispered. “Where is your friend?”
Langdon felt a chill. This killer is here for both of us.
Langdon made a show of glancing away from Sienna, over his shoulder into the darkness from which they’d come. “She has nothing to do with this. You want me.”
Langdon prayed that Sienna was now making progress along the wall. If she could sneak beyond the viewing platform, she could then quietly cross back to the central boardwalk, behind the spike-haired woman, and move toward the door.
The assassin again raised her light and scanned the empty garret behind him. With the glare momentarily out of his eyes, Langdon caught a sudden glimpse of a form in the darkness behind her.
Oh God, no!
Sienna was indeed making her way across a strut in the direction of the central boardwalk, but unfortunately, she was only ten yards behind their attacker.
Sienna, no! You’re too close! She’ll hear you!
The beam returned to Langdon’s eyes again.
“Listen carefully, Professor,” the assassin whispered. “If you want to live, I suggest you trust me. My mission has been terminated. I have no reason to harm you. You and I are on the same team now, and I may know how to help you.”
Langdon was barely listening, his thoughts focused squarely on Sienna, who was now faintly visible in profile, climbing deftly up onto the walkway behind the viewing platform, entirely too close to the woman with the gun.
Run! he willed her. Get the hell out of here!
Sienna, however, to Langdon’s alarm, held her ground, crouching low in the shadows and watching in silence.
Vayentha’s eyes probed the darkness behind Langdon. Where the hell did she go? Did they separate?
Vayentha had to find a way to keep the fleeing couple out of Brüder’s hands. It’s my only hope.
“Sienna?!” Vayentha ventured in a throaty whisper. “If you can hear me, listen carefully. You do not want to be captured by the men downstairs. They will not be lenient. I know an escape route. I can help you. Trust me.”
“Trust you?” Langdon challenged, his voice suddenly loud enough that anyone nearby could hear him. “You’re a killer!”
Sienna is nearby, Vayentha realized. Langdon is talking to her … trying to warn her.
Vayentha tried again. “Sienna, the situation is complicated, but I can get you out of here. Consider your options. You’re trapped. You have no choice.”
“She has a choice,” Langdon called out loudly. “And she’s smart enough to run as far from you as possible.”
“Everything’s changed,” Vayentha insisted. “I have no reason to hurt either of you.”
“You killed Dr. Marconi! And I’m guessing you’re also the one who shot me in the head!”
Vayentha knew that the man was never going to believe she had no intention of killing him.
