Midnight

puke-green variety that was produced for federal, state, and local government purchase; a pickup and van both bearing the seal of the city and the legend WATER AUTHORITY; a hulking street-sweeping machine; a large truck with wooden sides and tailgate; and four police cars, all Chevy sedans.
    The quartet of black-and-whites were what interested Sam because they were equipped with VDTs linking them to the police department's central computer. Moonlight Cove owned eight patrol cars, a large number for a sleepy coastal town, five more than other communities of similar size could afford and surely in excess of need.
    But everything about this police department was bigger and better than necessary, which was one of the things that had triggered silent alarms in the minds of the Bureau agents who'd come to investigate the deaths of Sanchez and the Bustamantes.
    Moonlight Cove had twelve full-time and three part-time officers, plus four full-time office support personnel. A lot of manpower. Furthermore, they were all receiving salaries competitive with law-enforcement pay scales in major West Coast cities, therefore excessive for a town as small as this. They had the finest uniforms, the finest office furniture, a small armory o' handguns and riot guns and tear gas, and—most astonishing of all—they were computerized to an extent that would have been the envy of the boys manning the end-of-the-world bunkers at the Strategic Air Command in Colorado.
    From his bristly nook in the fragrant evergreen hedge, Sam studied the lot for a couple of minutes to be sure no one was sitting in any of the vehicles or standing in deep shadows along the back of the building. Levolor blinds were closed at the lighted windows on the ground floor, so no one inside had a view of the parking area.
    He took a pair of soft, supple goatskin gloves from a jacket pocket and pulled them on.
    He was ready to move when he heard something in the alley behind him. A scraping noise. Back the way he'd come.
    Pressing deeper into the hedge, he turned his head to search for the source of the sound. A pale, crumpled cardboard box, twice the size of a shoebox, slid along the blacktop, propelled by the breeze that was increasingly rustling the leaves of the shrubs and trees. The carton met a garbage can, wedged against it, and fell silent.
    Streaming across the alley, flowing eastward on the breeze, the fog now looked like smoke, as if the whole town were afire. Squinting back through that churning vapor, he satisfied himself that he was alone, then turned and sprinted to the nearest of the four patrol cars in the unfenced lot.
    It was locked.
    From an inner jacket pocket, he withdrew a Police automobile lock Release Gun, which could instantly open any lock without damaging the mechanism. He cracked the car, slipped in behind the steering wheel, and closed the door as quickly and quietly as possible.
    Enough light from the sodium-vapor lamps penetrated the car for him to see what he was doing, though he was experienced enough to work virtually in the dark. He put the lock gun away and took an ignition-socket wrench from another pocket. In seconds he popped the ignition-switch cylinder from the steering column, exposing the wires.
    He hated this part. To click on the video-display mounted on the car's console, he had to start the engine; the computer was more powerful than a lap-top model and communicated with its base data center by energy-intensive microwave transmissions, drawing too much power to run off the battery. The fog would cover the exhaust fumes but not the sound of the engine. The black-and-white was parked eighty feet from the building, so no one inside was likely to hear it. But if someone stepped out of the back door for some fresh air or to take one of the off-duty cruisers out on a call, the idling engine would not escape notice. Then Sam would be in a confrontation that—given the frequency of violent death in this town—he might not survive.
    Sighing softly, lightly depressing the accelerator with his right foot, he separated the ignition wires with one gloved hand and twisted the bare contact points together. The engine turned over immediately, without any harsh grinding.
    The computer screen blinked on.
    The police department's elaborate computerization was provided free by New Wave Microtechnology because they were supposedly using Moonlight Cove as a sort of testing ground for their own systems and software. The source of the excess
