Ben settled into his seat and glanced down to make sure his work-helmet was racked beside him. He reached over and flipped a bank of switches on the instrument panel. "All communications to 'on,'" he said. Clay made a checkmark on his list. "All pre-engine start check complete," Clay replied.

  "In that case, the senior trooper said, "let's give Beulah some exercise. Start engines."

  Clay's fingers danced across the array of buttons on his seat arms and flicked lightly at the throttle knobs. From deep within the engine compartment came the muted, shrill whine of the starter engines, followed a split-second later by the full-throated roar of the jets as they caught fire. Clay eased the throttles back and the engine noise softened to a muffled roar.

  Martin fingered a press-panel on the right arm of his seat.

  "Car 56 to Philly Control," Ben called.

  The speakers mounted around the cab came to life. "Go ahead Five Six."

  "Five Six fired up and ready to roll," Martin said.

  "Affirmative Five Six," came the reply. "You're clear to roll. Philly Check estimates white density 300; green, 840; blue, 400; yellow, 75."

  Both troopers made mental note of the traffic densities in their first one-hundred-mile patrol segment; an estimated three hundred vehicles for each ten miles of thruway in the white or fifty to one hundred miles an hour lane; eight hundred forty vehicles in the one hundred to one hundred fifty miles an hour green, and so on. More than sixteen thousand westbound vehicles on the thruway in the first one hundred miles; nearly five thousand of them traveling at speeds between one hundred fifty and three hundred miles an hour.

  Over the always-hot intercom throughout the big car Ben called out. "All set, Kelly?"

  "I'm making coffee," Kelly answered from the galley. "Let 'er roll."

  Martin started to kick off the brakes, then stopped. "Ooops," he exclaimed, "almost forgot." His finger touched another button and a blaring horn reverberated through the vehicle.

  In the galley, Kelly hurled herself into a corner. Her body activated a pressure plant and a pair of mummy-like plastifoam plates slid curvingly out the wall and locked her in a soft cocoon. A dozen similar safety clamps were located throughout the car at every working and relaxation station.

  In the same instance, both Ben and Clay touched another plate on their control seats. From kiosk-type columns behind each seat, pairs of body-molded crash pads snapped into place to encase both troopers in their seats, their bodies cushioned and locked into place. Only their fingers were loose beneath the spongy substance to work arm controls. The half-molds included headforms with a padded band that locked across their foreheads to hold their heads rigidly against the backs of their reinforced seats. The instant all three crew members were locked into their safety gear, the bull horn ceased.

  "All tight," Ben called out as he wiggled and tried to free himself from the cocoon. Kelly and Clay tested their harnesses.

  Satisfied that the safety cocoons were operating properly, Ben released them and the molds slid back into their recesses. The cocoons were triggered automatically in any emergency run or chase at speeds in excess of two hundred miles an hour.

  Again he kicked off the brakes, pressed down on the foot feed and Car 56—Beulah—rolled out of the Philadelphia motor pool on the start of its ten-day patrol.

  * * *

  The motor pool exit opened into a quarter-mile wide tunnel sloping gently down into the bowels of the great city. Car 56 glided down the slight incline at a steady fifty miles an hour. A mile from the mouth of the tunnel the roadway leveled off and Ben kicked Beulah up another twenty-five miles an hour. Ahead, the main tunnel ended in a series of smaller portal ways, each emblazoned with a huge illuminated number designating a continental thruway.

  Ben throttled back and began edging to the left lanes. Other patrol cars were heading down the main passageway, bound for their assigned thruways. As Ben eased down to a slow thirty, another patrol vehicle slid alongside. The two troopers in the cab waved. Clay flicked on the "car-to-car" transmit.

  The senior trooper in Car 104 looked over at Martin and Ferguson. "If it isn't the gruesome twosome," he called. "Where have you been? We thought the front office had finally caught up with you and found out that neither one of you could read or write and that they had canned you."

  "We can't read," Ben quipped back. "That's why we're still on the job. The front office would never hire anyone who would embarrass you two by being smarter than either of you. Where're you headed, Eddie?"

  "Got 154-north," the other officer said.

  "Hey," Clay called out, "I've got a real hot doll in Toronto and I'll gladly sell her phone number for a proper price."

  "Wouldn't want to hurt you, Clay," the other officer replied. "If I called her up and took her out, she'd throw rocks at you the next time you drew the run. It's all for your own good."

  "Oh, go get lost in a cloverleaf," Clay retorted.

  The other car broke the connection and with a wave, veered off to the right. The thruway entrances were just ahead. Martin aimed Beulah at the lighted orifice topped by the number 26-W. The patrol car slid into the narrower tunnel, glided along for another mile, and then turned its bow upwards. Three minutes later, they emerged from the tunnel into the red patrol lane of Continental Thruway 26-West. The late afternoon sky was a covering of gray wool and a drop or two of moisture struck the front face of the cab canopy. For a mile on either side of the police lane, streams of cars sped westward. Ben eyed the sky, the traffic and then peered at the outer hull thermometer. It read thirty-two degrees. He made a mental bet with himself that the weather bureau was off on its snow estimates by six hours. His Vermont upbringing told him it would be flurrying within the hour.

  He increased speed to a steady one hundred and the car sped silently and easily along the police lane. Across the cab, Clay peered pensively at the steady stream of cars and cargo carriers racing by in the green and blue lanes—all of them moving faster than the patrol car.

  The young officer turned in his seat and looked at his partner.

  "You know, Ben," he said gravely, "I sometimes wonder if those oldtime cowboys got as tired looking at the south end of northbound cows as I get looking at the vanishing tail pipes of cars."

  The radio came to life.

  "Philly Control to Car 56."

  Clay touched his transmit plate. "This is Five Six. Go ahead."

  "You've got a bad one at Marker 82," Control said. "A sideswipe in the white."

  "Couldn't be too bad in the white," Ben broke in, thinking of the one-hundred mile-an-hour limit in the slow lane.

  "That's not the problem," Control came back. "One of the sideswiped vehicles was flipped around and bounded into the green, and that's where the real mess is. Make it code three."

  "Five Six acknowledge," Ben said. "On the way."

  He slammed forward on the throttles. The bull horn blared and a second later, with MSO Kelly Lightfoot snugged in her dispensary cocoon and both troopers in body cushions, Car 56 lifted a foot from the roadway, and leaped forward on a turbulent pad of air. It accelerated from one hundred to two hundred fifty miles an hour.

  The great red emergency lights on the bow and stern began to blink and from the special transmitter in the hull a radio siren wail raced ahead of the car to be picked up by the emergency receptor antennas required on all vehicles.

  The working part of the patrol had begun.

  * * *

  Conversation died in the speeding car, partly because of the concentration required by the troopers, secondly because all transmissions whether intercom or radio, on a code two or three run, were taped and monitored by Control. In the center of the instrument panel, an oversized radiodometer was clicking off the mileage marks as the car passed each milestone. The milestone posts beamed a coded signal across all five lanes and as each vehicle passed the marker, the radiodometer clicked up another number.

  Car 56 had been at MM 23 when the call came. Now, at better than four m
iles a minute, Beulah whipped past MM 45 with ten minutes yet to go to reach the scene of the accident. Light flurries of wet snow bounced off the canopy, leaving thin, fast-drying trails of moisture. Although it was still a few minutes short of 1700 hours, the last of the winter afternoon light was being lost behind the heavy snow clouds overhead. Ben turned on the patrol car's dazzling headlight and to the left and right, Clay could see streaks of white lights from the traffic on the green and blue lanes on either side of the quarter-mile wide emergency lane.

  The radio filled them in on the movement of other patrol emergency vehicles being routed to the accident site. Car 82, also assigned to NAT 26-West, was more than one hundred fifty miles ahead of Beulah. Pittsburgh Control ordered Eight Two to hold fast to cover anything else that might come up while Five Six was handling the current crisis. Eastbound Car 119 was ordered to cut across to the scene to assist Beulah's crew, and another eastbound patrol vehicle was held in place to cover for One One Nine.

  At mile marker 80, yellow caution lights were flashing on all westbound lanes, triggered by Philadelphia Control the instant the word of the crash had been received. Traffic was slowing down and piling up despite the half-mile wide lanes.

  "Philly Control this is Car 56."

  "Go ahead Five Six."

  "It's piling up in the green and white," Ben said. "Let's divert to blue on slowdown and seal the yellow."

  "Philly Control acknowledged," came the reply.

  The flashing amber caution lights on all lanes switched to red. As Ben began de-acceleration, diagonal red flashing barriers rose out of the roadway on the green and white lanes at the 85 mile marker and lane crossing. This channeled all traffic from both lanes to the left and into the blue lane where the flashing reds now prohibited speeds in excess of fifty miles an hour around the emergency situation. At the same time, all crossovers on the ultra high yellow lane were sealed by barriers to prevent changing of lanes into the over-congested area.

  As Car 56's speed dropped back below the two hundred mile an hour mark the cocoon automatically slid open. Freed from her safety restraints, Kelly jumped for the rear entrance of the dispensary and cleared the racking clamps from the six auto-litters. That done, she opened another locker and reached for the mobile first-aid kit. She slid it to the door entrance on its retractable casters. She slipped on her work helmet with the built-in transmitter and then sat down on the seat by the rear door to wait until the car stopped.

  Car 56 was now less than two miles from the scene of the crash and traffic in the green lane to the left was at a standstill. A half mile farther westward, lights were still moving slowly along the white lane. Ahead, the troopers could see a faint wisp of smoke rising from the heaviest congregation of headlights. Both officers had their work helmets on and Clay had left his seat and descended to the side door, ready to jump out the minute the car stopped.

  Martin saw a clear area in the green lane and swung the car over the dividing curbing. The big tracks floated the patrol car over the two-foot high, rounded abutment that divided each speed lane. Snow was falling faster as the headlight picked out a tangled mass of wreckage smoldering a hundred feet inside the median separating the green and white lanes. A crumpled body lay on the pavement twenty feet from the biggest clump of smashed metal, and other fragments of vehicles were strung out down the roadway for fifty feet. There was no movement.

  NorCon thruway laws were strict and none were more rigidly enforced than the regulation that no one other than a member of the patrol set foot outside of their vehicle while on any thruway traffic lane. This meant not giving any assistance whatsoever to accident victims. The ruling had been called inhuman, monstrous, unthinkable, and lawmakers in the three nations of the compact had forced NorCon to revoke the rule in the early days of the thruways. After speeding cars and cargo carriers had cut down twice as many do-gooders on foot at accident scenes than the accidents themselves caused, the law was reinstated. The lives of the many were more vital than the lives of a few.

  Martin halted the patrol vehicle a few feet from the wreckage and Beulah was still rocking gently on her tracks by the time both Patrol Trooper Clay Ferguson and MSO Kelly Lightfoot hit the pavement on the run.

  In the cab, Martin called in on the radio. "Car 56 is on scene. Release blue at Marker 95 and resume speeds all lanes at Marker 95 in—" he paused and looked back at the halted traffic piled up before the lane had been closed "—seven minutes." He jumped for the steps and sprinted out of the patrol car in the wake of Ferguson and Kelly.

  The team's surgeon was kneeling beside the inert body on the road. After an ear to the chest, Kelly opened her field kit bag and slapped an electrode to the victim's temple. The needle on the encephalic meter in the lid of the kit never flickered. Kelly shut the bag and hurried with it over to the mass of wreckage. A thin column of black, oily smoke rose from somewhere near the bottom of the heap. It was almost impossible to identify at a glance whether the mangled metal was the remains of one or more cars. Only the absence of track equipment made it certain that they even had been passenger vehicles.

  Clay was carefully climbing up the side of the piled up wrecks to a window that gaped near the top.

  "Work fast, kid," Martin called up. "Something's burning down there and this whole thing may go up. I'll get this traffic moving."

  He turned to face the halted mass of cars and cargo carriers east of the wreck. He flipped a switch that cut his helmet transmitter into the remote standard vehicular radio circuit aboard the patrol car.

  "Attention, please, all cars in green lane. All cars in the left line move out now, the next line fall in behind. You are directed to clear the area immediately. Maintain fifty miles an hour for the next mile. You may resume desired speeds and change lanes at mile Marker 95. I repeat, all cars in green lane . . ." he went over the instructions once more, relayed through Beulah's transmitter to the standard receivers on all cars. He was still talking as the traffic began to move.

  By the time he turned back to help his teammates, cars were moving in a steady stream past the huge, red-flashing bulk of the patrol car.

  Both Clay and Kelly were lying flat across the smashed, upturned side of the uppermost car in the pile. Kelly had her field bag open on the ground and she was reaching down through the smashed window.

  "What is it, Clay?" Martin called.

  The younger officer looked down over his shoulder. "We've got a woman alive down here but she's wedged in tight. She's hurt pretty badly and Kelly's trying to slip a hypo into her now. Get the arm out, Ben."

  Martin ran back to the patrol car and flipped up a panel on the hull. He pulled back on one of the several levers recessed into the hull and the big wrecking crane swung smoothly out of its cradle and over the wreckage. The end of the crane arm was directly over Ferguson. "Lemme have the spreaders," Clay called. The arm dipped and from either side of the tip, a pair of flanges shot out like tusks on an elephant. "Put 'er in neutral," Clay directed. Martin pressed another lever and the crane now could be moved in any direction by fingertip pulls at its extremity. Ferguson carefully guided the crane with its projecting tusks into the smashed orifice of the car window. "O.K., Ben, spread it."

  The crane locked into position and the entire arm split open in a "V" from its base. Martin pressed steadily on the two levers controlling each side of the divided arm and the tusks dug into the sides of the smashed window. There was a steady screeching of tearing and ripping metal as the crane tore window and frame apart. "Hold it," Ferguson yelled and then eased himself into the widened hole.

  "Ben," Kelly called from her perch atop the wreckage, "litter."

  Martin raced to the rear of the patrol car where the sloping ramp stood open to the lighted dispensary. He snatched at one of the autolitters and triggered its tiny drive motor. A homing beacon in his helmet guided the litter as it rolled down the ramp, turned by itself and rolled across the pavement a foot behind him. It stopped when he stopped and Ben touched another switch, cu
tting the homing beacon.

  Clay's head appeared out of the hole. "Get it up here, Ben. I can get her out. And I think there's another one alive still further down."

  Martin raised the crane and its ripper bars retracted. The split arms spewed a pair of cables terminating in magnalocks. The cables dangled over the ends of the autolitter, caught the lift plates on the litter and a second later, the cart was swinging beside the smashed window as Clay and Kelly eased the torn body of a woman out of the wreckage and onto the litter. As Ben brought the litter back to the pavement, the column of smoke had thickened. He disconnected the cables and homed the stretcher back to the patrol car. The hospital cart with its unconscious victim rolled smoothly back to the car, up the ramp and into the dispensary to the surgical table.

  Martin climbed up the wreckage beside Kelly. Inside the twisted interior of the car, the thick smoke all but obscured the bent back of the younger trooper and his powerful handlight barely penetrated the gloom. Blood was smeared over almost every surface and the stink of leaking jet fuel was virtually overpowering. From the depths of the nightmarish scene came a tortured scream. Kelly reached into a coverall pocket and produced another sedation hypo. She squirmed around and started to slip down into the wreckage with Ferguson. Martin grabbed her arm. "No, Kelly, this thing's ready to blow. Come on, Clay, get out of there. Now!"
