Shepley leaned back, letting the cool air drain the sweat off his face. ‘Once I tried to kill someone,’ he explained tersely. ‘After they cured me I found I wanted to kill myself instead.’ He reached down to the hand-brake as they gathered speed. ‘For ten thousand dollars I can go back on probation. Here I thought there would be a freemasonry of sorts. But then you’ve been kind enough, Doctor.’

‘Don’t worry, we’ll get you a winning tape.’ He leaned forward, shielding his eyes from the stellar glare, gazing down at the little cantonment of gutted time-tombs on the shore of the lake. In all there were about a dozen pavilions, their roofs holed, the group Traxel had shown to Shepley after his arrival when he demonstrated how the vaults were robbed.

‘Shepley! Look, lad!’

‘Where? I’ve seen them before, Doctor. They’re stripped.’

The Old Man pushed him away. ‘No, you fool. Three hundred yards to the west, by the long ridge where the big dunes have moved. Can you see them now?’ He drummed a white fist on Shepley’s knee. ‘You’ve made it, lad. You won’t need to be frightened of Traxel or anyone else.’

Shepley jerked the car to a halt. As he ran ahead of the Old Man towards the escarpment he could see several of the time-tombs glowing along the sky lines, emerging briefly from the dark earth like the tents of a spectral caravan.

For ten millennia the Sea of Vergil had served as a burial ground, and the 1,500 square miles of restless sand were estimated to contain over twenty thousand tombs. All but a minute fraction had been stripped by the successive generations of tomb-robbers, and an intact spool of the 17th Dynasty could now be sold to the Psycho-History Museum at Tycho for over 3,000 dollars. For each preceding dynasty, though none older than the 12th had ever been found, there was a bonus.

There were no corpses in the time-tombs, no dusty skeletons. The cyber-architectonic ghosts which haunted them were embalmed in the metallic codes of memory tapes, three-dimensional molecular transcriptions of their living originals, stored among the dunes as a stupendous act of faith, in the hope that one day the physical re-creation of the coded personalities would be possible. After five thousand years the attempt had been reluctantly abandoned, but out of respect for the tomb-builders their pavilions were left to take their own hazard with time in the Sea of Vergil. Later the tomb-robbers had arrived, as the historians of the new epochs realized the enormous archives that lay waiting for them in this antique limbo. Despite the time-wardens, the pillaging of the tombs and the illicit traffic in dead souls continued.

‘Doctor! Come on! Look at them!’

Shepley plunged wildly up to his knees in the silver-white sand, diving from one pavilion to the next like a frantic puppy.

Smiling to himself, the Old Man climbed slowly up the melting slope, submerged to his waist as the fine crystals poured away around him, feeling for spurs of firmer rock. The cupola of the nearest tomb tilted into the sky, only the top six inches of the casements visible below the overhang. He sat for a moment on the roof, watching Shepley dive about in the darkness, then peered through the casement, brushing away the sand with his hands.

The tomb was intact. Inside he could see the votive light burning over the altar, the hexagonal nave with its inlaid gold floor and drapery, the narrow chancel at the rear which held the memory store. Low tables surrounded the chancel, carrying beaten goblets and gold bowls, token offerings intended to distract any pillager who stumbled upon the tomb.

Shepley came leaping over to him. ‘Let’s get into them, Doctor! What are we waiting for?’

The Old Man looked out over the plain below, at the cluster of stripped tombs by the edge of the lake, at the dark ribbon of the gyro-rail winding away among the hills. The thought of the fortune that lay at his fingertips left him unmoved. For so long now he had lived among the tombs that he had begun to assume something of their ambience of immortality and timelessness, and Shepley’s impatience seemed to come out of another dimension. He hated stripping the tombs. Each one robbed represented, not just the final extinction of a surviving personality, but a diminution of his own sense of eternity. Whenever a new tomb-bed emerged from the sand he felt something within himself momentarily rekindled, not hope, for he was beyond that, but a serene acceptance of the brief span of time left to him.

‘Right,’ he nodded. They began to cleave away the sand piled around the door, Shepley driving it down the slope where it spilled in a white foam over the darker basaltic chips. When the narrow portico was free the Old Man squatted by the timeseal. His fingers cleaned away the crystals embedded between the tabs, then played lightly over them.

Like dry sticks breaking, an ancient voice crackled Orion, Betelgeuse, Altair, What twice-born star shall be my heir, Doomed again to be this scion — ‘Come on, Doctor, this is a quicker way.’ Shepley put one leg up against the door and lunged against it futilely. The Old Man pushed him away. With his mouth close to the seal, he rejoined.

‘Of Altair, Betelgeuse, Orion.’

As the doors accepted this and swung back he murmured: ‘Don’t despise the old rituals. Now, let’s see.’ They paused in the cool, unbreathed air, the votive light throwing a pale ruby glow over the gold drapes parting across the chancel.

The air became curiously hazy and mottled. Within a few seconds it began to vibrate with increasing rapidity, and a succession of vivid colours rippled across the surface of what appeared to be a cone of light projected from the rear of the chancel. Soon this resolved itself into a three-dimensional image of an elderly man in a blue robe.

Although the image was transparent, the brilliant electric blue of the robe revealing the inadequacies of the projection system, the intensity of the illusion was such that Shepley almost expected the man to speak to them. He was well into his seventies, with a composed, watchful face and thin grey hair, his hands resting quietly in front of him. The edge of the desk was just visible, the proximal arc of the cone enclosing part of a silver inkstand and a small metal trophy. These details, and the spectral bookshelves and paintings which formed the backdrop of the illusion, were of infinite value to the Psycho-History institutes, providing evidence of the earlier civilizations far more reliable than the funerary urns and goblets in the anteroom.

Shepley began to move forward, the definition of the persona fading slightly. A visual relay of the memory store, it would continue to play after the code had been removed, though the induction coils would soon exhaust themselves. Then the tomb would be finally extinct.

Two feet away, the wise unblinking eyes of the long dead magnate stared at him steadily, his seamed forehead like a piece of pink transparent wax. Tentatively, Shepley reached out and plunged his hand into the cone, the myriad vibration patterns racing across his wrist. For a moment he held the dead man’s face in his hand, the edge of the desk and the silver inkstand dappling across his sleeve.

Then he stepped forward and walked straight through him into the darkness at the rear of the chancel.

Quickly, following Traxel’s instructions, he unbolted the console containing the memory store, lifting out the three heavy drums which held the tape spools. Immediately the persona began to dim, the edge of the desk and the bookshelves vanishing as the cone contracted. Narrow bands of dead air appeared across it, one, at the level of the man’s neck, decapitating him. Lower down the scanner had begun to misfire. The folded hands trembled nervously, and now and then one of his shoulders gave a slight twitch. Shepley stepped through him without looking back.
