Inferno: (Robert Langdon Book 4)

way.
    As Langdon looked on, his peripheral vision suddenly picked up movement to his left—an ominous black form rising out of the water in front of Brüder. Langdon wheeled and stared into the looming darkness, half expecting to see some kind of leviathan rearing up from beneath the surface.
    Brüder had stopped short, apparently having seen it, too.
    In the far corner, a wavering black shape rose some thirty feet up the wall. The ghostly silhouette looked nearly identical to that of the plague doctor who’d appeared in Zobrist’s video.
    It’s a shadow , Langdon realized, exhaling. Brüder’s shadow.
    The shadow had been cast as Brüder moved past a submerged spotlight in the lagoon, exactly, it seemed, as Zobrist’s shadow had done in the video.
    “This is the spot,” Langdon called out to Brüder. “You’re close.”
    Brüder nodded and continued inching his way out into the lagoon. Langdon moved along the railing, staying even with him. As the agent moved farther and farther away, Langdon stole another quick glance toward the orchestra to make sure Brüder had not been noticed.
    Nothing.
    As Langdon again returned his gaze to the lagoon, a glint of reflected light caught his eye on the boardwalk at his feet.
    He looked down and saw a tiny puddle of red liquid.
    Blood.
    Strangely, Langdon was standing in it.
    Am I bleeding?
    Langdon felt no pain, and yet he frantically began searching himself for some injury or possible reaction to an unseen toxin in the air. He checked his nose for a possible bleed, his fingernails, his ears.
    Baffled as to where the blood had come from, Langdon glanced around, confirming that he was indeed alone on the deserted walkway.
    Langdon looked down at the puddle again, and this time he noticed a tiny rivulet flowing along the boardwalk and collecting in the low spot at his feet. The red liquid, it seemed, was coming from somewhere up ahead and trickling down an incline in the boardwalk.
    Someone is injured up there , Langdon sensed. He glanced quickly out at Brüder, who was nearing the center of the lagoon.
    Langdon strode quickly up the boardwalk, following the rivulet. As he advanced toward the dead end, the rivulet became wider, flowing freely. What in the world? At this point it turned into a small stream. He broke into a jog, following the flowing liquid all the way to the wall, where the boardwalk suddenly ended.
    Dead end.
    In the murky darkness, he found a large pool, which was glistening red, as if someone had just been slaughtered here.
    In that instant, as Langdon watched the red liquid dripping off the boardwalk into the cistern, he realized that his original assessment was mistaken.
    It’s not blood.
    The red lights of the vast space, combined with the red hue of the boardwalk, had created an illusion, giving these clear droplets a reddish-black tint.
    It’s just water.
    Instead of bringing a sense of relief, the revelation infused him with blunt fear. He stared down at the puddle of water, now seeing splashes on the banister … and footprints.
    Someone climbed out of the water here.
    Langdon spun to call out to Brüder, but he was too far away and the music had progressed into a fortissimo of brass and timpani. It was deafening. Langdon suddenly felt a presence beside him.
    I’m not alone out here.
    In slow motion, Langdon turned toward the wall where the boardwalk dead-ended. Ten feet away, shrouded in dark shadows, he was able to discern a rounded form, like a large stone cloaked in black cloth, dripping in a pool of water. The form was motionless.
    And then it moved.
    The form elongated, its featureless head rotating upward from its bowed position.
    A person huddled in a black burka , Langdon realized.
    The traditional Islamic body covering left no skin showing, but as the veiled head turned toward Langdon, two dark eyes materialized, staring out through the narrow slit of the burka’s face covering, locking intently on Langdon.
    In an instant, he knew.
    Sienna Brooks exploded from her hiding place. She accelerated to a sprint in a single stride, plowing into Langdon and driving him to the ground as she raced off down the boardwalk.

CHAPTER 93
    OUT IN THE lagoon, Agent Brüder had stopped in his tracks. The halogen beam of his Tovatec penlight had just picked up the sharp glint of metal up ahead on the submerged cistern floor.
    Barely breathing, Brüder took a delicate step closer, cautious not to create any turbulence in the water. Through the glassy
