There was not a sound, save the echo of his own footsteps, as Tristan wound his way through the narrow streets, high cliffs of ancient houses on either side, down which the white disk of the moon penetrated but a yard or two. At the foot of the Palatine Hill, cutting into the moonlight, the Colosseum rose before him, gaunt, vast, sinister, a silhouette of enormous blackness, pierced as with innumerable empty eyes flooded by greenish, ghostly moonlight. Necromancers and folk practising the occult arts dwelled in ancient houses built with the honey-colored Travertine, stolen from the Hill of the Cæsars. It was said that strange sounds echoed from the arena at night; that the voices of those who had died for the faith in the olden days could be heard screaming in agony at certain periods of the moon. Gigantic masses of gaunt masonry rose around him as, with fleet steps, he traversed the deserted thoroughfares. In the greenish moonlight he could discern the tumbled ruins of arches and temples scattered about the dark waste. His gaze also encountered the frowning masonry of more recent buildings. The castellated palace of one of the Frescobaldi had been reared right across that ancient site, including in its massive bulk more than one monument of imperial days. As he approached the region of the Arch of the Seven Candles, as the Arch of Titus with its carving of the Jewish Candelabrum borne in triumph was then called, Tristan walked more warily. The reputed dangers of the Campo Vaccino knocking at the gates of his memory, he loosened the sword in his scabbard. He had, by this time, arrived at the end of the street, that curves towards the Arch of Titus, which commands the avenue of lone holm-oaks, leading towards the Appian Way. Suddenly a man emerged from the shadows. He was armed with sword and buckler, his body was covered with hauberk of mail and he wore the conical steel casque in vogue since Norman arms served as the military model. Roger and Tristan confronted each other, the former's face tense, drawn, white; the latter with calm eyes in which there was the light of a great regret. An expression not easy to read lay in Laval's eyes, eyes that scanned Tristan from under half-shut lids. "So you have come?" the stranger said brutally, after a brief and painful pause. "I have never broken my word," Tristan replied. "Well spoken! I shall be plain and brief, if you will own the truth." "I have nothing to conceal, my lord." Roger's eyes gleamed with yet livelier malice. "Where is the Lady Hellayne? Where is my wife?" "As God lives, I know not. Yet--I would give my life, to know." "Indeed! You may be given that chance. You are frank at least--" "I may have wronged you in heart, my lord,--but never in deed--" Tristan replied. "What I have seen, I have seen," the other snarled viciously. "Perchance this silent devotion accounts also for many other things." "I do not understand, my lord."
