Nightside 03 - Nightingales Lament

special process, behind this sealed door. A scientific marvel, if I do say so myself."
    I glared suddenly at the steel door. "If you're about to tell me you've got a nuclear pile in there . . ."
    "No, no . . ."
    "Or a contained singularity . . ."
    "Nothing so crude, John. My process is perfectly safe, with no noxious by-products. Though I'm afraid I can't show it to you. Some things have to remain secret."
    And then he broke off, and we both looked round sharply as we heard something. A harsh juddering began in one of the machines at the far end of the hall, and black smoke billowed suddenly from a vent, before an alarm shrilled loudly and the machine shut itself down. Vincent shrank back against the steel door.
    "He's here! The saboteur . . . he's never got this far before. He must have been following us all this time . . . Are you armed, John?"
    "I don't use guns," I said. "I've never felt the need."
    "Normally I don't, either, but ever since this shit began happening, I've felt a lot more secure knowing I've got a little something to even out the odds." Vincent produced a gleaming silver gun from inside his jacket. It looked sleek and deadly and very futuristic. Vincent hefted it proudly. "It's a laser. Amplified light to fight the forces of darkness. Another of my inventions. I always meant to do more with it, but the power plant took over my life. I can't see anyone, John. Can you see anyone?"
    A machine a little further down the hall exploded suddenly. More black smoke, and the hum of the other machines rose significantly, as though they were having to work harder. A third machine blew apart like a grenade, throwing sharp-edged steel shrapnel almost the length of the hall. Some of the overhead lights flickered and went out. There were shadows everywhere now, deep and dark. Some of the other machines began making unpleasant, threatening noises. And still there was no sign of the saboteur anywhere.
    Vincent's face was pale and sweaty, and his hand trembled as he swept his laser gun back and forth, searching for a target. "Come on, come on," he said hoarsely. "You're on my territory now. I'm ready for you."
    Something pale flashed briefly at the corner of my eye. I snapped around, but it was already gone. It appeared again, just a glimpse of white in the shadows between two machines. It flashed back and forth, appearing and disappearing in the blink of an eye, darting up and down the length of the hall. Glimmers of shimmering white as fleeting as moonlight, but I thought I was beginning to make out an impression of a pale, haunted face. It moved in the shadows, never venturing out into the light. But it was gradually drawing nearer. Heading for us, or perhaps for the steel door behind us and the secret vulnerable heart of Prometheus Inc.
    My first thought was that it had to be a ghost of some kind, maybe a poltergeist. Which would explain why the CCTV cameras hadn't been able to see anything. Ghosts could operate in science- or magic-dominated areas, provided their motivation was strong enough. In which case, Vincent needed a priest or an exorcist, not a private eye. I suggested as much to Vincent, and he shrugged angrily.
    "I had my people do a full background check on this location before we began construction; and they didn't turn up anything. The whole area was supposed to be entirely free from magical or paranormal influences. That's why I built here. I'm the Mechanic, I build things. It's a talent, just like your talent for finding things, John. I don't know about ghosts. You're the expert on these matters. What do we do?"
    "Depends what the ghost wants," I said.
    "It wants to destroy me! I would have thought that was obvious. What was that?"
    The white figure was flashing in and out of the shadows, on every side at once, drawing steadily closer all the time. Shimmering white, ragged round the edges, with long, reaching arms and a dark malevolent glare in an indistinct face. It gestured abruptly, and suddenly all the shrapnel scattered across the floor rose and hammered us like a metallic hailstorm. I put my arms over my head and did my best to shield Vincent with my body. The rain of objects ended as suddenly as it began, and we looked up to see something pale and dangerous squatting on one of the machines, tearing it apart with unnatural strength. Vincent howled with rage and fired his laser, but the figure was gone long before the light beam could reach it. I glared about me, my back pressed hard against
