In the distance somewhere an engine growled. A moment later, from a different quarter, a woman’s voice cried out faintly. Bridgman moved to the rail, over the intervening roof-tops saw two figures silhouetted against the sky on the elevator head of an apartment block, then heard Louise Woodward call out again. She was pointing up at the sky with both hands, her long hair blown about her face, Travis trying to restrain her. Bridgman realized that she had misconstrued Merril’s descent, assuming that the fallen astronaut was her husband. He climbed on to the edge of the balcony, watching the pathetic tableau on the distant roof.

Again, somewhere among the dunes, an engine moaned. Before Bridgman could turn around, a brilliant blade of light cleft the sky in the south-west. Like a speeding comet, an immense train of vaporizing particles stretching behind it to the horizon, it soared towards them, the downward curve of its pathway clearly visible. Detached from the rest of the capsules, which were now disappearing among the stars along the eastern horizon, it was little more than a few miles off the ground.

Bridgman watched it approach, apparently on a collision course with the hotel. The expanding corona of white light, like a gigantic signal flare, illuminated the roof-tops, etching the letters of the neon signs over the submerged motels on the outskirts of the town. He ran for the doorway, as he raced down the stairs saw the glow of the descending capsule fill the sombre streets like a hundred moons. When he reached his room, sheltered by the massive weight of the hotel, he watched the dunes in front of the hotel light up like a stage set. Three hundred yards away the low camouflaged hull of the wardens’ beach-car was revealed poised on a crest, its feeble spotlight drowned by the glare.

With a deep metallic sigh, the burning catafalque of the dead astronaut soared overhead, a cascade of vaporizing metal pouring from its hull, filling the sky with incandescent light. Reflected below it, like an expressway illuminated by an aircraft’s spotlights, a long lane of light several hundred yards in width raced out into the desert towards the sea. As Bridgman shielded his eyes, it suddenly erupted in a tremendous explosion of detonating sand. A huge curtain of white dust lifted into the air and fell slowly to the ground. The sounds of the impact rolled against the hotel, mounting in a sustained crescendo that drummed against the windows. A series of smaller explosions flared up like opalescent fountains. All over the desert fires flickered briefly where fragments of the capsule had been scattered. Then the noise subsided, and an immense glistening pall of phosphorescing gas hung in the air like a silver veil, particles within it beading and winking.

Two hundred yards away across the sand was the running figure of Louise Woodward, Travis twenty paces behind her. Bridgman watched them dart in and out of the dunes, then abruptly felt the cold spotlight of the beach-car hit his face and flood the room behind him. The vehicle was moving straight towards him, two of the wardens, nets and lassos in hand, riding the outboard.

Quickly Bridgman straddled the balcony, jumped down into the sand and raced towards the crest of the first dune. He crouched and ran on through the darkness as the beam probed the air. Above, the glistening pall was slowly fading, the particles of vaporized metal sifting towards the dark Martian sand. In the distance the last echoes of the impact were still reverberating among the hotels of the beach colonies farther down the coast.

Five minutes later he caught up with Louise Woodward and Travis. The capsule’s impact had flattened a number of the dunes, forming a shallow basin some quarter of a mile in diameter, and the surrounding slopes were scattered with the still glowing particles, sparkling like fading eyes. The beach-car growled somewhere four or five hundred yards behind him, and Bridgman broke off into an exhausted walk. He stopped beside Travis, who was kneeling on the ground, breath pumping into his lungs. Fifty yards away Louise Woodward was running up and down, distraughtly gazing at the fragments of smouldering metal. For a moment the spotlight of the approaching beach-car illuminated her, and she ran away among the dunes. Bridgman caught a glimpse of the inconsolable anguish in her face.

Travis was still on his knees. He had picked up a piece of the oxidized metal and was pressing it together in his hands.

‘Travis, for God’s sake tell her! This was Merril’s capsule, there’s no doubt about it! Woodward’s still up there.’

Travis looked up at him silently, his eyes searching Bridgman’s face. A spasm of pain tore his mouth, and Bridgman realized that the barb of steel he clasped reverently in his hands was still glowing with heat.

‘Travis!’ He tried to pull the man’s hands apart, the pungent stench of burning flesh gusting into his face, but Travis wrenched away from him. ‘Leave her alone, Bridgman! Go back with the wardens!’

Bridgman retreated from the approaching beach-car. Only thirty yards away, its spotlight filled the basin. Louise Woodward was still searching the dunes. Travis held his ground as the wardens jumped down from the car and advanced towards him with their nets, his bloodied hands raised at his sides, the steel barb flashing like a dagger. At the head of the wardens, the only one unmasked was a trim, neat-featured man with an intent, serious face. Bridgman guessed that this was Major Webster, and that the wardens had known of the impending impact and hoped to capture them, and Louise in particular, before it occurred.

Bridgman stumbled back towards the dunes at the edge of the basin. As he neared the crest he trapped his foot in a semicircular plate of metal, sat down and freed his heel. Unmistakably it was part of a control panel, the circular instrument housings still intact.

Overhead the pall of glistening vapour had moved off to the north-east, and the reflected light was directly over the rusting gantries of the former launching site at Cape Canaveral. For a few fleeting seconds the gantries seemed to be enveloped in a sheen of silver, transfigured by the vaporized body of the dead astronaut, diffusing over them in a farewell gesture, his final return to the site from which he had set off to his death a century earlier. Then the gantries sank again into their craggy shadows, and the pall moved off like an immense wraith towards the sea, barely distinguishable from the star glow.

Down below Travis was sitting on the ground surrounded by the wardens. He scuttled about on his hands like a frantic crab, scooping handfuls of the virus-laden sand at them. Holding tight to their masks, the wardens manoeuvred around him, their nets and lassos at the ready. Another group moved slowly towards Bridgman.

Bridgman picked up a handful of the dark Martian sand beside the instrument panel, felt the soft glowing crystals warm his palm. In his mind he could still see the silver-sheathed gantries of the launching site across the bay, by a curious illusion almost identical with the Martian city he had designed years earlier. He watched the pall disappear over the sea, then looked around at the other remnants of Merril’s capsule scattered over the slopes. High in the western night, between Pegasus and Cygnus, shone the distant disc of the planet Mars, which for both himself and the dead astronaut had served for so long as a symbol of unattained ambition. The wind stirred softly through the sand, cooling this replica of the planet which lay passively around him, and at last he understood why he had come to the beach and been unable to leave it.

Twenty yards away Travis was being dragged off like a wild dog, his thrashing body pinioned in the centre of a web of lassos. Louise Woodward had run away among the dunes towards the sea, following the vanished gas cloud.
