Suddenly he paused. A small cabinet of sandal wood, concealed behind the jutting stone, had caught his eye. It was painted to resemble the rock and the untrained eye would not linger upon it. A small keyhole was revealed, but the key had been taken away.
Tristan stood irresolute, with straining eyes and listening ear. Not a sound was audible. Even the piping of the night wind in the rock fissures seemed to have died to silence. With quick resolution he inserted one of the sharp-edged flints and gave a wrench.
When the top receded he could not repress an outcry. A chill coursed coldly through his veins. His breath came and went in sobs, as from one half drowned.
He only glanced at what was before him for the fraction of a second. But he knew what had made the very soul within him shudder and his bones grind, as if in mortal agony.
It was as though Hell itself had opened the gates. He staggered back in a paroxysm of horror.—
With a grim, set face Tristan closed the top of the cabinet and replaced it on the rocky ledge. Thus he stood, his face buried in his hands. Could the All-seeing God permit such an outrage and let the perpetrators live?
But there was no time for reflection. At any moment one of the muffled phantoms might return, and indeed he thought he heard steps approaching through one of the rock galleries. He crouched in breathless, agonized suspense, for it did not suffer him longer in these caverns of crime and death.
He dimly remembered the direction in which the nocturnal company had departed and, after some research, he discovered a narrow corridor that seemed to slope upward through the gloom. His lantern having been broken to atoms, the taper held out little promise of life beyond a brief space of time during which he must find the entrance of the cavern, if he did not wish to meet a fate even worse than death in the event of discovery.
Grimly resolved Tristan raised the flickering taper and entered the gallery on his left. The Stygian gloom almost extinguished the feeble light, though he noted every object he passed, every turn in the tortuous ascent.
After some time which seemed eternity he at last perceived a dim glow at the extremity of the gallery, and soon found himself before the outer cavity of the stone wall, in a region of the city that seemed miles removed from the place where he had entered.
