Dark Rivers of the Heart

sectors of the city embraced big expanses of barren land. At a glance they seemed to be only enormous vacant lotsbut, in fact, they were manifestations of the brooding desert, which was just biding its time. When the wind blew hard enough, the encircled desert angrily flung off its thin disguise, storming into the surrounding neighborhoods.
        Half blinded by the seething tempest of sand, with shatters of dust hissing across the windshield, Spencer prayed for more: more wind, more clouds of grit. He wanted to vanish like a ghost ship disappearing into a fog.
        He glanced at the rearview mirror. Behind him, visibility was limited to ten or fifteen feet.
        He started to accelerate but reconsidered. Already he was plunging into the dry blizzard at suicidal speed. The street was no more visible ahead than it was behind. If he encountered a stopped or slow-moving vehicle, or if he suddenly crossed an intersection against the flow of traffic, the least of his worries would be the four homicidal men in the supercharged fedwagon.
        One day, when the axis of the earth shifted just the tiniest fraction of a degree or when the jet streams of the upper troposphere suddenly deepened and accelerated for reasons mysterious, the wind and desert would no doubt conspire to tumble Vegas into ruin and bury the remains beneath billions of cubic yards of dry, white, triumphant sand.
        Maybe that moment had arrived.
        Something thumped into the back end of the Explorer, jolting Spencer.
        The rearview mirror. The Chevy. On his ass. The fedwagon receded a few feet into the swirling sand, then leaped forward again, tapping the truck, maybe trying to make him spin out, maybe just letting him know they were there.
        He was aware of Rocky looking at him, so he looked at Rocky.
        The dog seemed to be saying, Okay, now what?
        They passed the last of the undeveloped land and exploded into a silent clarity of sandless air. In the cold steely light of the pending storm, they had to abandon all hope of slipping away like Lawrence of Arabia into the swirling silicate cloaks of the desert.
        An intersection lay half a block ahead. The signal light was red.
        The flow of traffic was against him.
        He kept his foot on the accelerator, praying for a gap in the passing traffic, but at the last moment he rammed the brake pedal to the floor, to avoid colliding with a bus. The Explorer seemed to lift onto its front wheels, then rocked to a halt in a shallow drainage swale that marked the brink of the intersection.
        Rocky yelped, lost his grip on the upholstery, and slid into the leg space in front of his seat, under the dashboard.
        Belching pale-blue fumes, the bus trundled past in the nearest of the four traffic lanes.
        Rocky eeled around in the cramped leg space and grinned up at Spencer.
        "Stay there, pal. It's safer."
        Ignoring the advice, the dog scrambled onto the seat again as Spencer accelerated into traffic in the reeking wake of the bus.
        As Spencer turned right and swung around the bus, the rearview tyiirror captured the mold-green sedan bouncing across the same shallow swale in the pavement and arcing right into the street, as smoothly as if it were airborne.
        "That sonofabitch knows how to drive."
        Behind him, the Chevy appeared around the side of the city bus.
        It was coming fast.
        Spencer was less concerned about losing them than about being shot at again before he could get away.
        They would have to be crazy to open fire from a moving car, in traffic, where stray bullets could kill uninvolved motorists or pedestrians.
        This wasn't Chicago in the Roaring Twenties, wasn't Beirut or Belfist, wasn't even Los Angeles, for God's sake.
        On the other hand, they hadn't hesitated to blast away at him on the street in front of Theda Davidowitzs apartment building. Shot at him.
        No questions first. No polite reading of his constitutional rights. hell, they hadn't even made, a serious effort to confirm that he was, in fact, the person they believed him to be. They wanted him badly enough to risk killing the wrong man.
        They seemed convinced that he'd learned something of staggering importance about Valerie and that he must be terminated. In truth, he knew less about the woman's past than he knew about Rocky's.
        If they ran him down in
