comes.”
    “Okay,” Donny replied, but the connection had already been cut.
     

THE DS-TWO MINE, NEVADA
     
    T he floor of the box canyon was in shadow long before sunset, making it easier for Mercer to pretend it was almost dawn rather than a few minutes until dusk. Just one of the tricks he used when working a graveyard shift. The other mental games he played weren’t doing much to alleviate the tension cramping his shoulders, the nagging pain in his lower back or the gritty, red rims around his eyes. He hadn’t spent as much time at the mine as the others, yet he’d pushed himself so hard he felt the deep exhaustion infecting them all. The work pace had been brutal and he hadn’t yet recovered from Canada.
    In the command trailer he stooped over the seismograph, his attention focused on the steady line of ink trailing across the revolving drum of paper. The stylus remained motionless but wouldn’t for long. Although it meant reporting to work an hour before his shift, he’d gotten in the habit of watching the results of Donny Randall’s blasts.
    Red Harding stepped into the trailer where they kept the seismograph and several other pieces of scientific equipment. He placed a cup of coffee at Mercer’s elbow. Mercer acknowledged with a nod. Observing the seismograph had become a “morning” ritual for both men.
    “Still haven’t figured it out, huh?” Red sipped from the Pepsi that gave him his jolt of caffeine.
    Outside, the men of Donny’s team made their way past the trailer on their way toward their rooms for showers, dinner in the mess, and bed. The schedule left most too tired to bother with the satellite television, pool table or other amenities in the rec hall.
    “Not yet,” Mercer said absently. The big clock on the wall showed that a minute remained before Donny would fire the charges his men had just planted.
    Harding scratched his sunburned bald spot. “He has a different technique is all.”
    Mercer had noticed the anomaly over the course of the ten days he’d been on-site. Both work shifts removed similar amounts of rock with each blast, although Donny used slightly more explosives. What tickled the back of Mercer’s mind was that the seismograph readings indicated Donny’s shots were slightly smaller than Mercer’s. Somehow Randall managed to reduce the amount of seismic shock from the charges he laid, creating less stress in the surrounding strata, something miners strove for. Mercer had watched him working but had found nothing to indicate how he was doing it.
    It was ego driving him to find the answer, he knew. He didn’t want to admit the possibility that Randall the Handle was the better blaster.
    “And if you average out our teams,” Red added, “we have cleared six feet more tunnel than he has. He ain’t better than us. He’s just overpacking his holes after he places his ’splosives. That accounts for the damping effect.”
    “You’re probably right,” Mercer replied, not wholly satisfied with the answer but unable to find another.
    The earth and the stylus jumped at the same instant. The bump at the soles of their feet was much less dramatic than what happened on the seismograph. The steel needle traced a jagged line on the paper like an EKG recording a heart attack. A moment later the shock waves dissipated and the machine flat-lined as if the patient had died. On an adjoining computer Mercer brought up comparison patterns from previous blasts. Like before, Donny’s shot showed a two percent decrease in shock waves from what Mercer’s team managed. The six additional feet that his men had excavated wasn’t enough to make up that difference.
    Mercer’s mouth turned down at the corners.
    The trailer door crashed open. Randall loomed at the entrance, his face and clothes covered in dirt. Pomade and dust turned his hair into a shiny helmet that clung to his skull. The dye he used to keep his hair unnaturally black bled down his forehead in gray streaks of sweat.
