Frankenstein

opposite hers, twenty feet beyond her range of vision.
    She could try to stay to the middle of the dock and hope to glimpse a moving figure along either railing. But the thick fog was disorienting, and she had nothing to guide her on a straight course.
    Anyway, almost certainly, Chang had hurried away from shore along this particular dock because he had arrived—and intended to depart—by boat. He wouldn’t double back any more than he would climb a railing and leap into the drink.
    Deep in the murk, Carson halted, held her breath, listened. At first she heard nothing, then only the chortle and chuckle of gentle waves rolling through the pilings on which the dock rested.
    No doubt Michael approached behind her, but quietly, no longer at a run. She glanced back but saw no man-shape or shadow in the whiteout.
    She released her pent-up breath and moved forward cautiously.After perhaps twenty feet, she stopped again and still heard nothing but the seemingly amused waters of the placid bay.
    The air smelled of brine and seaweed and creosote, and the fog was cool in her mouth when she inhaled.
    Farther along the dock, when she paused a third time, she heard a faint thump, a stealthy creak. Initially, the sounds seemed to come from under the timber flooring.
    A clink of metal on metal turned her attention to the right side of the dock. She cleaved the fog, reached the railing, and followed it bayward until she found where it turned to serve a gangway.
    The descending planking was wet and slippery, not just from the fog but from fungus or lichen that had colonized the wood of the long-unused ramp. Her hands were moist, as well, and the pistol slick with condensation.
    If she fell or merely skidded, Chang might be waiting for the noise. If he chanced a fog-blind fusillade, luck was as likely to be on his side as on hers. Of all the bullets in the barrage, one might leave Scout motherless.
    Cautiously, Carson reached the bottom of the gangway and stepped onto the flat wood of the slip. A motor yacht did not so much appear in the fog as materialize from it, as though it were a ghost boat that haunted the bay.
    Engines silent, with no running lights or cabin lights aglow, the double-deck vessel had an enclosed helm station above the main-deck cabins. Carson was nearer the bow, and the stern vanished in the fog, but based on the proportions of what she could see, the craft must measure about sixty feet, big enough to be a coastal cruiser that could trade the bay for the open sea.
    No mooring line secured the yacht to the cleat in the planking. As Carson moved toward the stern, she thought the vessel appeared to be adrift in the slip. Chang had evidently untied before boarding and must even now be ascending to the helm station, perhaps by a ladder on the port side.
    The boarding gate in the starboard deck railing stood open. He had most likely been hesitant to close it behind him and make another metal-on-metal sound that would reveal his location in the shrouding murk.
    During the moment of boarding, Carson was especially vulnerable, with a one-hand grip on her pistol, left hand on the cold stainless-steel railing, body in motion and off balance. She swung aboard silently, however, and without incident.
    The narrow starboard deck led forward past a few portholes but only as far as a door. The elevated foredeck lacked gunwales.
    Carson moved quietly aft to the spacious stern deck.
    Even in the purling mist, she could discern two doors in the after bulkhead. She supposed that one must lead to a lounge and other quarters, while the second probably opened on a companionway that led down to the galley and staterooms.
    Chang would not have gone below or forward from here. He would have wanted to get quickly to the helm and must already be up there, at the controls.
    Between the bulkhead doors, a steep slope of stairs led up to the open deck behind the helm station. Embedded low-voltage LEDs, probably controlled by a light sensor that activated them at darkfall, defined the edge of each step.
    Standing at the foot of the stairs, she could see nothing above except dense, slowly eddying fog.
    Expecting to hear the engines turn over at any second, Carson decided to go up fast, without using the handrail, gun in both hands, leaning forward from the waist for balance.
    Before she could put a foot on the first tread, she felt the muzzle of a gun against the nape of her neck, and an involuntary vulgarity hissed between her clenched
