loose bricks.
    Looking around, Smithback found himself in a long, narrow tunnel. Water and steam pipes ran overhead like thick gray veins. The ceiling was low, but not so low that a man as tall as Smithback couldn’t stand upright. Evening light filtered in through ceiling grates spaced at hundred yard intervals.
    The reporter followed the stooped, low figure, moving ahead of him in the dim light. Once in a while the rumble of a nearby train would fill the dank space; Smithback could feel the sound more in his bones than his ears.
    They began walking northward along what seemed to be an endless tunnel. After ten or fifteen minutes, Smithback began to feel a nagging worry. “Excuse me,” he said, “but why the long walk?”
    “Mephisto keeps the nearest entrances to our community secret.”
    Smithback nodded, making a wide detour around the swollen body of a dead dog. It wasn’t surprising these tunnel dwellers were a little paranoid, but this was getting ridiculous. They’d walked far enough north to be under Central Park.
    Soon, the tunnel began to curve gently to the right. Smithback could make out a series of steel doors set into the thick concrete wall. Overhead a large pipe ran, water dripping from its padded covering. A sign on the padding read DANGER: CONTAINS ASBESTOS FIBERS. AVOID CREATING DUST. CANCER AND LUNG DISEASE HAZARD. Stopping and digging one hand into his rags, Tail Gunner extracted a key and placed it in the lock of the closest door.
    “How’d you get that key?” Smithback asked.
    “We have many skills in our community,” the man replied, pulling open the door and ushering the journalist through.
    As the door shut behind Smithback, the blackness of night rushed forward to meet him. Realizing how much he’d instinctively relied on the dim light that had filtered down from the grates, Smithback had a sudden feeling of panic.
    “Don’t you have a flashlight?” he stammered.
    There was a scratching sound, then the flaring of a wooden match. In the flickering illumination, Smithback saw a series of cement steps leading downward as far as the matchlight penetrated.
    Tail Gunner snapped his wrist and the match went out.
    “Satisfied?” came the dull, monotonic voice.
    “No,” Smithback replied quickly. “Light another.”
    “When it is necessary.”
    Smithback felt his way down the staircase, his hands spread on the cool slick walls for balance. They descended for what seemed an eternity. Suddenly, another match flared, and Smithback saw that the stairs ended in an enormous railroad tunnel, its silver tracks gleaming dully in the orange light.
    “Where are we now?” Smithback asked.
    “Track 100,” the man said. “Two levels down.”
    “Are we there yet?”
    The match flickered out, and darkness descended again.
    “Follow me,” came the voice. “When I say stop, you stop. Immediately.”
    They ventured onto the tracks. Smithback found himself fighting down panic once again as he stumbled over the iron rails.
    “Stop,” came the voice. Smithback halted as another match flared. “See that?” Tail Gunner said, pointing to a gleaming bar of metal with a bright yellow line painted next to it. “That’s a third rail. It’s electrified. Don’t step on it.”
    The match died out. Smithback heard the man take a few steps in the close, humid darkness.
    “Light another!” he cried.
    A match flared. Smithback took a broad step over the third rail.
    “Are there any more of those?” he asked, pointing to the rail.
    “Yes,” the little man said. “I’ll show you.”
    “Jesus,” said Smithback as the match died. “What happens if you step on one?”
    “The current explodes your body, blows off your arms, legs, and head,” the disembodied voice said. There was a pause. “It’s always better not to step on it.”
    A match flared again, illuminating another yellow-painted rail. Smithback stepped gingerly over it, then watched as Tail Gunner pointed to a small hole in the far wall
