Maitland speculated shrewdly that preparations were now in band for a final retreat of the COE inner core-government and service chiefs, with a few people such as Marshall -to some secret bastion where survival could be assured for a good deal longer. He had tried to report his discovery at Marshall 's Park Lane house, but the senior officers at the depot were too busy to listen to him, and anyway had no authority outside the unit. Besides, Hardoon, with his army of construction workers and fleets of equipment, might well be working for the government.
When he finally slung his suitcase up into one of the half-tracked personnel carriers and climbed in after it, there were only a dozen men left in the depot.
The troop carrier was shunted up against one of the Centurions, the two jibs locked together. Both vehicles were loaded with concrete slabs three feet long and 18 inches thick, canted to exaggerate the original slope of the armor plate and provide the minimum wind resistance.
Maitland settled himself among the kitbags and suitcases and peered out through the narrow glass window, an inch-high slit just behind his head. Only two others were with him; an RAF flight sergeant and a young signals corporal.
After a long wait the engines roared out and they edged forward up the exit ramp. As they neared the end of the ramp the horizontal door was retracted and the 180 mph airstream moving across the flat parade ground lifted the carrier out like an enormous hand, slewing it around under a hail of fist-sized stones. The driver gunned the engine and pulled them back on course, and with the Centurion pulling ahead they moved toward the gateway and then through into Green Park. Maitland looked out at the darkened slopes. Stumps of trees stuck up through the turfless soil, littered with stones, gravel and miscellaneous debris that piled up against the embankment walls like refuse in an abandoned municipal dump.
They stopped just past Hyde Park Corner in the entrance to Knightsbridge. Maitland pressed his face to the window slit, looked out at the dim outlines of the office blocks and apartment buildings in the darkness. All of them were shaking perceptibly, heavy tremors jolting the roadway under the carrier. The roofs had been stripped away and Maitland could see the sky through the open top-floor windows. Many of the upper floors had fallen in. All the small shops and boutiques had been completely gutted, their plate glass smashed, interiors cleaned out to the last hatpin and hair curler.
Swinging to the right of the roadway, on the way dislodging the shell of a Jaguar that had trapped itself in a shopfront and now skittered off ahead of them, they avoided the debris piled across their path and pressed on toward the Brompton Road. As they passed Lowndes Square Maitland craned to look up at his apartment house, counting the floors to his own apartment. The building was still intact, but all its lights were out. As they moved on he wondered what had happened to Susan.
Harrod's department store lay in ruins, brownstone facing tiles lying thickly across the roadway, the wind picking like a thousand vultures at the tangle of girders and masonry, detaching fragments of furniture and tattered drapery and carrying them away in its fleeting clasp.
Shaking his head ruefully, Maitland left the window and searched for his cigarettes. He was taking out the pack when the half-track braked sharply. For a moment it hesitated and then began to tip backward and rolled slowly down a shallow incline that had opened in the roadway under the rear section of the vehicle.
Above the din of the wind Maitland could hear the driver shouting into his radio. He felt the Centurion throw its engine into a lower gear, trying to pull them out of the subsidence. The weight of the carrier had apparently caved in a shallow sewer traversing the road. Tilting at a ten-degree angle, the carrier's tracks raced and skated. Gradually it slid helplessly down the incline, pulling the Centurion after it. Finally it rooted itself immovably. The driver raced his engine, flogging the gears like a maniac, while the Centurion jerked and thrust helplessly. Then both engines stopped, and for a few minutes the drivers bellowed into their microphones.
Through the window Maitland could see the sides of a six-footdeep ditch. Behind was the ragged edge of the asphalt roadway, ahead the massive outline of the tank, its rear track wheels still on the road.
The driver opened his communicating door and came swarming aft, furious with what had happened, waving his arms and shouting: "Off, off, off! Don't sit here like a lot of helpless sheep."
The flight sergeant bridled, wondering whether to pull his rank on the corporal, then thought better of it.
"What do we do now, mate?" he asked.
The driver kicked the suitcases out of the way, shouted scornfully, "Walk, what else? I'm bloody well not going to carry you back!"
He unlocked the rear doors, pushed them open. The Centurion switched on its rear lights, flooding the interior of the carrier. To the left on the pavement above, Maitland could see the gray humped back of a pedestrian tunnel. Part of it had collapsed into the ditch, affording a convenient access point. The driver pointed to it.
"Take that back to Knightsbridge Underground," he barked at them. "Follow the Piccadilly Line to Hammersmith and you'll be picked up there. Got it?"
Maitland hesitated, then began to crawl along the bottom of the ditch toward the aperture in the tunnel. The wind drove overhead like an express train, sucking at the low-pressure space in the road, and he clung to the damp soil like a limpet. Reaching the tunnel, he pulled himself in, then helped the others who came after him.
When they were all inside they saw the Centurion roar into life and move sharply away from the ditch, its lights flashing, then swing round and drive off down the street.
The tunnel had originally been six feet high, but the wind pres… sure and the successive shells of reinforcing materials added during the past week had lowered the ceiling to little more than five feet off the ground. Here and there, at 50-yard intervals, a storm lantern cast a fitful glow over the dripping bags.
Crouching down, they moved forward, Maitland in the lead. it was only half a mile back to Knightsbridge, and luckily the tunnel was unbreached at any other point. A few people lay about in makeshift sleeping bags by the storm lights-claustrophobes, Maitland assumed, who were more terrified of their basements and the Underground than of the wind, and who preferred the surface tunnels with their long corridors and spaced lights. Tripping over abandoned clothing and cooking utensils, they reached the station in five minutes. The entranceway had been heavily fortified with reinforced concrete by the army. Two armed policemen in black wind suits checked their passes, then directed them to the signals unit set up in the ticket booth.
After the deserted, darkened streets, the station was a blaze of lights, packed with thousands of people huddled about on the upper level with their bundles of luggage, walling off crude cubicles with blankets and raincoats, cooking over primus stoves, queuing endlessly at the latrines. Sleeping figures and parcels of luggage crowded the floor. They picked their way over the outstretched limbs, trying not to disturb the fretfully sleeping children and older people, till they located the two signalers operating the radio transmitter.
