Just beyond the entrance the interior widened out and heightened until it was like the inside of a great cathedral or a giant tomb of antiquity. Both Czerda and his son switched on their torches, the powerful beams of which failed to penetrate the farthest reaches of this awesome man-made cave, and man-made it unquestionably was, for clearly visible on the towering side-walls were the thousands of vertical and horizontal scores where long-dead generations of Provençals had sawn away huge blocks of the limestone for building purposes.
The floor of this entrance cavern – for, vast though it was, it was no more than that – was pitted with rectangular holes, some of them large enough to hold a motor car, others wide and deep enough to bury a house. Scattered in a few odd corners were mounds of rounded limestone rock but, for the most part, the floor looked as if it had been swept only that day. To the right and left of the entrance cavern led off two other huge openings, the darkness lying beyond them total, impenetrable. A doom-laden place, implacable in its hostility, forebodng, menacing, redolent of death. But Czerda and his son seemed unaware of any of this, quite unmoved: they turned and walked confidently towards the entrance to the right-hand chamber.
Deep inside the heart of this vast warren, a slight figure, a barely distinguishable blur in the pale wash of moonlight filtering down through a crack in the cavern roof, stood with his back to a limestone wall, fingers splayed and pressed hard against the clammy rock behind him in the classically frozen position of the fugitive at bay. A youth, no more than twenty, he was clad in dark trousers and a white shirt. Around his neck he wore a silver crucifix on a slender silver chain. The crucifix rose and fell, rose and fell with metronomic regularity as the air rasped in and out of his throat and his heaving lungs tried vainly to satisfy the demands of a body that couldn’t obtain oxygen quickly enough. White teeth showed in what could have been a smile but was no smile, although frozen lips drawn back in the rictus of terror can look like one. The nostrils were distended, the dark eyes wide and staring, his face as masked in sweat as if it had been smeared with glycerine. It was the face of a boy with two demons riding on his shoulders: almost at the end of his physical resources, the knowledge of the inevitability of death had triggered off the unreasoning and irrecoverable panic that pushes a man over the edge of the abyss into the mindless depths of madness.
Momentarily, the fugitive’s breathing stopped entirely as he caught sight of two dancing pools of light on the floor of the cavern. The wavering beams, steadily strengthening, came from the left-hand entrance. For a moment the young gypsy stood as one petrified, but if reason had deserted him the instinct for survival was still operating independently, for with a harsh sobbing sound he pushed himself off the wall and ran towards the right-hand entrance to the cavern, canvas-soled shoes silent on the rocky floor. He rounded the corner, then slowed down suddenly, reached out groping hands in front of him as he waited for his eyes to become accustomed to the deeper darkness, then moved on slowly into the next cavern, his painfully gasping breathing echoing back in eerie whispers from the unseen walls around him.
Czerda and his son, their torch beams, as they advanced, ceaselessly probing through an arc of 180 degrees, strode off confidently through the archway linking the entrance cavern to the one just vacated by the fugitive. At a gesture from Czerda, both men stopped and deliberately searched out the furthermost recesses of the cavern: it was quite empty. Czerda nodded, almost as if in satisfaction, and gave a peculiar, low-pitched two-tone whistle.
In his hiding-place, which was no hiding-place at all, the gypsy appeared to shrink. His terrified eyes stared in the direction of his imagined source of the whistle. Almost at once, he heard an identical whistle, but one which emanated from another part of this subterranean labyrinth. Automatically, his eyes lined up to search out the source of this fresh menace, then he twisted his head to the right as he heard a third whistle, exactly the same in timbre and volume as the previous two. His staring eyes tried desperately to locate this third danger, but there was nothing to be seen but the all-encompassing darkness and no sound at all to break the brooding silence except the far-off keening of the gypsy violins, a far-off reminder of another safer and saner world that served only to intensify the sinister stillness inside that vaulted place of horror.
For a few moments he stood, fear-crazed now and wholly irresolute, then, within the space of as many seconds, the three double whistles came again, but this time they were all closer, much closer, and when he again saw the faint wash of light emanating from the two torches he had seen earlier, he turned and ran blindly in the only direction which seemed to afford a momentary respite, careless or oblivious of the fact that he might run into a limestone wall at any-moment. Reason should have told him this but he was now bereft of reason: it was but instinct again, the age-old one that told him that a man does not die before he has to.
He had taken no more than half-a-dozen steps when a powerful torch snapped on less than ten yards ahead of him. The fugitive stopped abruptly, staggering but not falling, lowered the forearm that he had flung up in automatic reflex to protect his eyes and stared for the first time, with narrowed eyes, in a barely conscious attempt to identify the extent and immediacy of this fresh danger confronting him, but all his shrinking eyes could make out was the vaguely discernible bulk of the shapeless figure of the man behind the torch. Then slowly, very slowly, the man’s other hand came forward until it was brightly lit by the beam of the torch: the hand held an evilly curved knife that glittered brilliantly in the torch-light. Knife and torch began to move slowly forward.
The fugitive whirled around, took two steps, then stopped as abruptly as he had before. Two other torches, knives again showing in their powerful beams, were scarcely further away than the man behind him. What was so terrifying, so nerve-destroying, about the measured advances of all three was the unhurriedly remorseless certainty.
‘Come now, Alexandre,’ Czerda said pleasantly. ‘We’re all old friends, aren’t we? Don’t you want to see us any more?’
Alexandre sobbed and flung himself to his right in the direction where the light from the three torches showed the entrance to yet another cavern. Panting as a deer does just before the hounds drag it down, he half-tumbled, half-ran through the entrance. None of his three pursuers made any attempt to cut him off or run after him: they merely followed, again walking with that same purposeful lack of haste.
Inside this third cavern, Alexandre stopped and looked wildly around. A small cavern this time, small enough to let him see that all the walls here were solid, hostilely and uncompromisingly solid, without as much as the tiniest aperture to offer any hope of furtherflight. The only exit was by the way he had come in and this was the end of the road.
Then the realization gradually penetrated his mind, numbed though it was, that there was something different about this particular cavern. His pursuers with their torches were not yet in sight, so how was it that he could see so well? Not clearly, there wasn’t enough light for that, but well enough in contrast with the Stygian darkness of the cavern he had just left behind.
Almost at his feet there lay a huge pile of rock and rubble, clearly the result of some massive fall or cave-in in the past. Instinctively, Alexandre glanced upwards. The rubble, piled at an angle of about forty degrees from the horizontal, didn’t seem to have a summit. It just stretched on and on and Alexandre’s gradually lifting eyes could see that it stretched upwards for a vertical height of at least sixty feet before it ended. And where it ended it had to end – for there, at the very top, was a circular patch of star-studded sky. That was where the light came from, he dimly realized, from some roof collapse of long ago.
His body was already beyond exhaustion but now some primeval drive had taken over and the body was no longer its own master, in much the same way as his mind had
